Abstract published with permission. Background: Needle decompression of the chest is indicated for patients in a critical condition with rapid deterioration who have a life-threatening tension pneumothorax. Aim: To reassure UK prehospital care providers that needle decompression of the chest is not commonly required in chest trauma patients, and most can be safely managed without it. Methods: Case studies as part of a major trauma network continuous review process have revealed instances of needle decompression in the absence of tension pneumothorax. Images are presented where needle decompression was attempted in the absence of tension pneumothorax. Context: Expert opinion from our networks multidisciplinary trauma team discuss the occurrence of tension pneumothorax in self-ventilating patients, and the idea that tension pneumothorax is rare in the UK civilian trauma population is acknowledged. Other causes of chest hypoventilation are discussed ...

Tension pneumoperitoneum is a potentially lethal complication of many procedures, including endoscopic ultrasound guided aspiration. We report the case of a 57-year-old male with pancreatic pseudo-cysts who developed tension pneumoperitoneum and circulatory collapse after endoscopic ultrasound. Initial treatment was successful with needle decompression. Emergency surgery revealed two perforations in the stomach which were manually sutured. The patient had an uneventful recovery and was discharged home on the seventh postoperative day. Tension pneumoperitoneum is a life-threatening complication and ...

Study patients: 11 consecutive adults with a diagnosis of pneumoperitoneum by CT. Control patients: 11 consecutive adults with severe acute abdominal pain with a diagnosis other than pneumoperitoneum by CT. US examination has been performed with a convex and a linear probe using the following scans: epigastrium, right and left hypocondrium, umbelical area and right hypocondrium. All exams were recorded in a video of 5 seconds and each videos reviewed by 2 radiologists and 2 senior physicians blinded to other imaging studies. The reviewers fulfilled a standardized form signing for each scan either presence or absence of pneumoperitonem signs (enhancement of the peritoneum stripe with ring-down artifacts or comet tails starting from peritoneum). If one of the signs of pneumopeitoneum was present in at least one scan, the patient was considered to have a US diagnosis of pneumoperitoneum. The reviewers also evaluated abdomen radiography for the presence/absence of pneumoperitoneum. CT was ...

OBJECTIVE To find out the duration of postoperative pneumoperitoneum and the factors that are responsible for its persistence. DESIGN Prospective open (non-random) study. SETTING County hospital, Denmark. SUBJECTS 32 patients over 18 years of age undergoing abdominal operations during a 6 month period. INTERVENTIONS Abdominal radiographs with the patient in the left lateral position were taken at fixed time intervals until no free air could be seen. MAIN OUTCOME MEASURES The amount of free air and the time postoperatively by which it had disappeared. RESULTS In 20 [corrected] patients the air had disappeared within 48 hours and only one patient (3%) had free air for more than five days postoperatively. High body mass index and a small initial amount of free air were associated with the shortest period of postoperative pneumoperitoneum. CONCLUSION Postoperative pneumoperitoneum disappeared within two days in most patients. Heavier patients and patients with small volumes of free air

On the third re-laparotomy, the silo was removed and the decision was made to definitively close his abdomen. Fascial suture was not possible because the central section remained with an insurmountable gap of 6 cm. We performed the posterior part of the components separation technique (CST) described by Ramirez et al. [4]. Longitudinal incisions of the two posterior rectal sheaths parallel and near his linea alba were made. We bluntly separated these sheaths from his rectus muscles, paying attention not to disturb the neurovascular bundles at the lateral rectal borders. This led to a good mobilization of the two rectal myofascial complexes (RMFCs), allowing apposition under acceptable tension. We used the Kloppel interrupted suture technique, and placed four Smead-Jones internal retention sutures. Our patient made an uneventful recovery, with the wound healing by primary intention.. The sample of the peritoneal exudate for culture and sensitivity taken during the initial operation did not grow ...

A recent JAMA article out of USC+LAC Medical Center investigated an alternative site for needle decompression in tension pneumothorax from the standard 2nd intercostal space (ICS) at the mid-clavicular line. Using CT scans in 680 trauma patients, they compared the 2nd ICS MCL to the 5th ICS at the anterior axillary line (AAL) using a…

This master thesis study uses seismic modeling to better understand the seismic response of the free gas that accumulates beneath hydrate-bearing sediments. To this end, I developed 12 different geological models ranging from very simple geometries to anticline structures. Within these models, I varied the distribution of free gas in the layers beneath the BSR. Sediment properties were taken from velocity profiles of the Storegga gas hydrate system and the density approximately estimated from a computed Gassmann diagram. Norsar 2D, Norsar 3D and Seisrox modeling programs were used to generate PSDM seismic images. Higher frequencies, large incident angle and long horizontal sampling distances has resulted in the generation of BSR as termination of enhanced reflection. The termination of the enhanced reflections coincided with anticlinal and dipping BSR in this study. The presence of intercalation of gas free and hydrate bearing layers above the dipping BSR and gas free and gas bearing sediments ...

All patients were immediately treated with broad-spectrum antibiotics and underwent subsequent surgical exploration. Patients A and C had a pneumoperitoneum, indicating free gas trapped within the peritoneal cavity but outside the lumen of the bowel. Patient B had a pneumomediastinum due to mediastinitis. Afterwards, they were admitted to the ICU for postoperative care. Patients A and B both went into severe septic shock. Against all odds, patient C recovered without any clinical sequelae. A complete summary of differential diagnoses regarding free gas can be found in table 1. Up to 49% of cases of a pneumoperitoneum may not be detected using conventional radiography. Therefore, it is recommended to make a CT scan, which can correctly identify the site of perforation in 86% of the cases.2 After taking microbiological cultures, broad-spectrum antibiotics should be started immediately if sepsis is suspected. However, there may also be causes of free gas for which antibiotics are not the direct ...

Objectives: In patients with gastric cancer, peritoneal dissemination is the most common metastasis. To predict future peritoneal recurrences, peritoneal lavage cytology is performed during operation. But even cytology-negative patients sometimes develop peritoneal recurrences. Thus an additional method to detect intraperitoneal free gastric cancer cells is necessary. We have developed a genetically engineered adenovirus, TelomeScan, which replicates and expresses GFP only in telomerase-activated cancer cells. Here we detected intraperitoneal free gastric cancer cells using TelomeScan, and investigated the correlation between the number of GFP-positive cells and patient prognosis.. Methods: Peritoneal wash was obtained from 69 gastric cancer patients during operation. The cells in the wash were infected with TelomeScan for 24 hours. Finally, GFP-positive cells were counted under a fluorescence microscope. In some GFP-positive cases immunofluorescence assay was added. Clinicopathological data ...

We have conducted a trial investigating the role of an increased dose of inhaled steroids within the context of an asthma action plan. In our study a double dose of inhaled beclomethasone had no beneficial effect on an asthma exacerbation compared with placebo, and this is evidence against using such an approach in asthma management. This finding has several implications, but these should be applied with due consideration to the limitations of this study.. The first criticism directed at many studies resulting in a negative outcome is that they lacked the power to detect an effect. Before commencing our study, we were unable to find any good data on which to perform power calculations and estimate sample size requirements and so we performed retrospective power calculations. Using the baseline PEFR data we can say that a sample of 28 children gave us an 80% chance of detecting a difference of 0.55 SD (5% of baseline PEFR) at the 5% level of significance. The 18 pairs of exacerbations available ...

In the above cases, we used the ultrasound to observe three abnormal air patterns that should alert the clinician to an intra-abdominal pathology, namely intraperitoneal air (case#2), portal venous gas (case#1), and intramural air (case#1).. Intraperitoneal air can be seen using the liver as an acoustic window. Indeed, the liver offers a unique echogenic window. Although the hepatic flexure of the colon can sometimes be found interposed, there is generally no bowel that creates artifact in the right upper quadrant. Free air will accumulate anteriorly in the supine position and create an air artifact interfering with the normal liver texture (Fig. 1). It is of importance not to press deeply with the ultrasound probe as this can shift small amount of free air away from the US field. This phenomenon of air interposition should be considered abnormal and is similar to the lung point shadow that occurs in a pneumothorax where ultrasound reveals loss of normal lung sliding [10]. We propose the term ...

The complications specific to laparoscopy are generally related to its inherent technical challenges and the physiologic effects of pneumoperitoneum. Reduced visualization and dexterous limitations may increase the risk of organ injury that may go seen, or unseen. Pneumoperitoneum with carbon dioxide to a standard pressure between 10 to 15 mmHg can predisopose to hypercarbia, reduced cardiac output, pneumothorax, or air embolus.. Postoperatively, retained carbon dioxide may serve as a diaphragmatic irritant, and referral of pain to the ipsilateral shoulder can be severe, but rarely lasting beyond 36 hours. Port site infections occur on a rare basis and can usually be treated expectantly. Hernias do occur at port sites, and are more common with ports greater than 5 mm in size, or where manipulation, replacement, or frequent torqueing on the port is common.. ...

Laparoscopic liver surgery has evolved over the last 2 decades. Advancements in surgical technology, surgical technique, and postoperative care have aided in lifting barriers to laparoscopic liver resections (LLR). LLR might decrease morbidity and hospitalisation stay compared to open approach, and importantly in liver surgery, may decrease postoperative costal pain. However, in hepatic surgery as in all abdominal procedures, laparoscopic approach is a mean but not a goal. The possibility of LLR should neither modify indications for surgery nor the type of resection. Physiologic modifications induced by CO2 pneumoperitoneum should be known by the surgical and anaesthetic team involved in LLR. Pneumoperitoneum decreases cardiac output, ...

M2.OR.4757) A 69-year-old male presents to the emergency department after a car crash. The patient is unconscious and his shirt is covered in blood. The patient has severe JVD and seems to be struggling to breathe. His temperature is 99.5°F (37.5°C), pulse is 160/min, blood pressure is 90/50 mmHg, respirations are 18/min, and oxygen saturation is 93% on room air. Large needle decompression is performed, and IV fluids are started. A pelvic binder is placed and a full trauma assessment is started. The patients physical exam is notable for multiple bruises and erythema over the ventral chest, arms, and pelvis. The patient has a type and screen sent off and a radiograph of the pelvis is ordered and is in Figure A. A radiograph of the chest is performed and is notable for multiple broken ribs. A FAST exam is ordered and returns negative for any signs of abdominal bleeding or cardiac tamponade. During this time, IV fluids are continued and a chest tube is placed. There is no drainage of blood from ...

Theres a saying in paramedicine: trauma is trauma. Basically that just means that it is what it is. Unlike a complex medical emergency with co-morbid factors on a patient with chronic conditions who takes ten medications, treatment for trauma is actually pretty simple. If it bleeds, plug it. If its floppy, splint it. Then go find a trauma surgeon quickly. Yet the real nuance to effective trauma care is staying ahead of injuries by anticipating problems before they happen and caring for the injuries that you cant see..

19 A recently published systematic review based on 11 studies, evaluating the severity of STP found a significant reduction associated to low-pressure pneumoperitoneum and also mentioned that the reduction was mostly evident during the first 24 hours of surgery.11,16-20. Another effective way of assessing pain is through the analgesic requirements of the patient. Reduced analgesic requirements not only signify improved patient wellbeing but also indicate a reduction of workload on the nursing staff. In our study the difference in the number of times the analgesic had to be administered between the two groups was statistically significant with the requirement being low in the LPLC group. Reduction in analgesic demand has also been confirmed by the Cochrane review by Gurusamy in 2009. 12 Our findings were also in concordance with those of Yasir et al who concluded their study with the remarks that the analgesic requirement is reduced significantly in LPLC and thus recuperates the quality of life ...

We describe a rare case of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing pyogenic liver abscess in a 59-year-old man. The patient was diagnosed as having a hollow viscus perforation based on a sudden onset of acute abdominal pain along with radiological evidence of bilateral subphrenic feee air (pneumoperitoneum), and underwent an emergency laparotomy. Contrary to expectations, the surgery revealed no perforations of the hollow viscus, but instead a ruptured liver abscess at the dome of the right hepatic lobe was identified associated with suppurative peritonitis. To the best of our knowledge, such a case of spontaneous pneumoperitoneum secondary to the rupture of a gas-containing liver abscess is extremely rare ...

Historical teaching instructs providers to place a needle in the second ICS at the mid-clavicular line (2ICS MCL) for tension pneumothorax. Free Open Access Medical Education (FOAM) sources such as Emergency Medicine Ireland have preached the more lateral approach for years; yet this teaching has not spread widely (outside of military circles where there seems to be better adoption). Change is difficult, particularly when it involves re-educating thousands of providers and it seems like this is the primary driver behind the 2ICS MCL remaining as the typical site for needle decompression.. However, several potential problems exist with the mid-clavicular approach that warrant consideration for assuming 4/5ICS AAL as the primary initial placement for needle decompression. ...

The prognostic significance of free cancer cells detected in peritoneal fluid at the time of rectal surgery remains unclear. A substantial number of patients will develop metastatic disease even with successful local treatment. This prospective non-randomized study investigated the prognostic value of intraperitoneal free cancer cells harvested in peritoneal lavage after surgery for rectal cancer. Mutational hotspots in mitochondrial DNA were examined as potential molecular signatures to detect circulating intraperitoneal free cancer cells when present in primary tumor and in lavage. Point mutations in mitochondrial DNA amplifications were determined in primary tumors and corresponding exfoliated intraperitoneal free cancer cells in lavage from 191 patients with locally advanced rectal cancer scheduled for radical treatment. Mitochondrial DNA target sequences were amplified by polymerase chain reaction and base substitutions were detected by denaturant, cycling temperature capillary electrophoresis.

Compressed air can cause serious damage to internal organs. The stomach is an organ that is rarely perforated due to its elasticity. However, intestines are weaker and thinner compared to the stomach. A 40-year-old male came to the emergency room with severe abdominal pain due to dyspnea. The patient experienced abdominal pain right after his coworker shot compressed air into the patients pants. The patient suffered from a rigid abdomen, and bed-side ultrasonography was carried out as soon as possible. Pneumoperitoneum was diagnosed by portable X-ray. After computed tomography, emergency paracentesis was carried out for decompression. After emergency paracentesis, the patients symptoms and vital signs were stabilized. After the procedure, the patient had an emergency laparotomy. ...

Results: The mean P(a-Et)CO2 gradient was 5.67 ± 1.36 mmHg 10 mins after induction of anesthesia in supine position (T1a). Ten minutes after LDP P(a-Et)CO2 gradient was 7.38 ± 1.45 mmHg (T1b) and this was significantly higher than T1a. After creation of pneumoperitoneum P(a-Et)CO2 values at 30, 60, 120 mins were significantly higher than the supine and LDP values. The P(a-Et)CO2 value 10 mins after release of pneumoperitoneum and 10 mins after making the patient supine were significantly higher than the T1a value. The highest value of P(a-Et)CO2 gradient was at 30 mins after creation of pneumoperitoneum (T30) i.e., 9.99 ± 1.70 mmHg. Pearson correlation coefficient showed that the degree of correlation varied considerably during surgery due to inter individual variability (R2 T1a vs. T60 was 0.61 vs 0.17).

Gastrointestinal tract perforations can occur for various causes such as peptic ulcer, inflammatory disease, blunt or penetrating trauma, iatrogenic factors, foreign body or a neoplasm that require an early recognition and, often, a surgical treatment. Ultrasonography could be useful as an initial diagnostic test to determine, in various cases the presence and, sometimes, the cause of the pneumoperitoneum. The main sonographic sign of perforation is free intraperitoneal air, resulting in an increased echogenicity of a peritoneal stripe associated with multiple reflection artifacts and characteristic comet-tail appearance. It is best detected using linear probes in the right upper quadrant between the anterior abdominal wall, in the prehepatic space. Direct sign of perforation may be detectable, particularly if they are associated with other sonographic abnormalities, called indirect signs, like thickened bowel loop and air bubbles in ascitic fluid or in a localized fluid collection, bowel or gallbladder

Local and systemic effects of pneumoperitoneum were evaluated. Treated mice were randomly assigned to a control group, an open cecectomy group, or a laparoscopic-simulated cecectomy group. When a tumor inoculum was injected into the peritoneal cavity, the frequency of tumors was not significantly different for mice in the laparoscopic-simulated and open cecectomy groups (60% vs 62%, respectively). There was no significant difference in survival time between the laparoscopic-simulated and open cecectomy groups, with median survivals of 24 days versus 22 days, ...

Laparoscopic alternatives to conventional surgical procedures confer many advantages to patients including reduced postoperative pain, shortened convalescence and, perhaps, improved disease-related outcomes. The diminished degree of immune dysfunction apparent with these techniques may underpin these beneficial aspects. However, minimal access is accompanied by various ancillary anesthetic and mechanical associations (including the induction of a carbon dioxide pneumoperitoneum), which must be considered in addition to reduced tissue trauma when attempting to correlate cause with effect. Furthermore, the opportunity to establish causation between the immunomodulatory aspects of laparoscopy and subsequent clinical outcome by prospective, randomized study is difficult because of the rapid incorporation of minimal access techniques into clinical practice. Therefore, experimental in vitro and in vivo studies must be used to complement the limitations of clinical studies in this area. Although the ...

By providing stable pneumoperitoneum, constant smoke evacuation, and valve-free access to the abdominal cavity, the AirSeal System has been demonstrated to reduce procedural time, resulting in increased operating efficiency.1. 1 George AK, Wimhofer R, Viola KV, Pernegger M, Costamoling W, Kavoussi LR, Loidl W. World J Urol. 2015 Mar 1.. * Constant smoke evacuation is only available in AirSeal and Smoke Evacuation modes.. ...

BACKGROUND: Portal triad clamping (PTC) may be required during laparoscopic liver resection to limit blood loss. The aim of this study was to test in a swine model the hypothesis that during laparoscopic PTC, increased intraperitoneal pressure may alter hepatic vein reverse circulation, inducing a more severe hepatic ischemia compared with PTC performed in laparotomy. METHODS: Fifteen pigs were randomized into three groups: laparoscopy (1 h of pneumoperitoneum at 15 mmHg and 3 h of surveillance), open PTC (1 h PTC through laparotomy and 3 h of reperfusion), and laparoscopic PTC (1 h PTC with 15 mmHg pneumoperitoneum and 3 h of reperfusion). PTC was performed under mesenteric decompression using a veno-venous splenofemoral ...

Intraperitoneal rectal injuries will cause. peritonitis, sepsis and even death if not detected early. Intraperitoneal free air (IFA) is usually diagnosed by an erect Chest X-ray [2]. If the erect chest X-ray was normal, then an abdominal CT scan is recommended. Point-of-care ultrasound has been recently used to detect IFA [3, 4]. Hereby, we report an unusual case of trans-anal rectal injury in which point-of-care ultrasound was of a great help for an early diagnosis. Case presentation A 45-year-old male presented to the Emergency Department complaining of lower abdominal pain and dysuria of two days https://www.selleckchem.com/products/ON-01910.html duration. His blood pressure was 120/80 mmHg, his pulse was 107 beat per minute and his temperature Mocetinostat supplier was 36.8°C.

TY - CHAP. T1 - Nonsurgical abdominal pain in the elderly. AU - Tyler, Katren R. AU - Kennedy, Maura. PY - 2016/5/31. Y1 - 2016/5/31. N2 - This chapter presents a case study of 71-year-old woman who presented to the emergency department (ED) with abdominal pain. The differential for abdominal pain in the elderly is broad as it may be the presenting symptom for illnesses involving intraperitoneal, and extraperitoneal structures. The chapter focuses on nonsurgical causes of acute abdominal pain in the elderly. The history and physical examination remains the cornerstone of the clinical evaluation, but can be challenging in the older patient with comorbidities. An electrocardiogram should be obtained in any older adult presenting with upper abdominal pain or vague, nonlocalizing abdominal pain. Diagnostic imaging studies are driven by the clinicians clinical assessment and differential diagnosis; however, the history and physical examination of the older patient with abdominal pain is often less ...

Riglers sign is a radiological sign of free intraperitoneal air, generally from a perforated viscus. It is the appearance of air on both sides of the bowel wall due to a large quantity of free air in the abdomen. It is important to be aware of the non-surgical causes of this appearance, one of which we describe here.. An 87-year-old man whose only medical history was of a long-standing, seemingly asymptomatic, diaphagramatic hernia (figure 1, preoperative film), underwent a total hip replacement with ...

We believe that there is substantial evidence to suggest that the patients presentation to the OSH was due to COVID-19. The chest X-ray on admission to the OSH as well as serial chest X-rays and a CT scan from the OSH demonstrated bilateral airspace opacities consistent with multifocal pneumonia and were compatible with COVID-19 presentation.27 The patient required high ventilator settings consistent with severe ARDS, which is a known complication of COVID-19. In addition, extensive culture, antigen and PCR testing was negative, which suggests an unusual causative agent for the patients severe pulmonary condition. Furthermore, there is a recent report of a patient on maintenance immunosuppression that had viral shedding of COVID-19 for 65 days, which supports our assumption that the patient had contracted COVID-19 prior to admission to the OSH.28 If our hypothesis is true, this case occurred before the first recorded case in Michigan. This implication is feasible as there was very limited ...

The injection of air into body cavities or tissues is a method that has been used for diagnostic purposes (e.g., perirenal insufflation, Rubins test, etc.) and also for therapy (e.g., pneumoperitoneum, pneumothorax, etc.). Though these technics have been considered to have real value, each has been fraught with the risk of serious or even fatal accidents from air embolism.1, 2, 3 Some accidents have been reported in the literature, but we have learned about a host of others only through personal communication. The frequency with which air embolism has been observed has varied with different procedures, but has been highest, ...

TY - JOUR. T1 - Cardiopulmonary responses to intravenous infusion of soluble and relatively insoluble gases. AU - Roberts, M. W.. AU - Mathiesen, K. A.. AU - Ho, H. S.. AU - Wolfe, Bruce. PY - 1997/4. Y1 - 1997/4. N2 - Background: Carbon dioxide is the current gas of choice for pneumoperitoneum, but hemodynamic and acid-base effects secondary to its systemic absorption have been reported. Various studies have suggested inert gases as alternatives. Methods: We studied the cardiopulmonary responses to intravenous infusion of carbon dioxide, nitrous oxide, argon, helium, and nitrogen in anesthetized swine. The gas was infused into the femoral vein at a rate of 0.1 ml · kg-1 · min-1 for 30 min. The changes in end-tidal CO2, mean arterial pressure, hemodynamics, and arterial blood gases were compared to baseline values. Results: No animals died during infusion of the soluble gases (CO2 and N2O). Three of the five pigs infused with nitrogen died suddenly at 20 and 30 min of infusion. The animals in ...

The amount of CH4 that could theoretically be released in the future is enormous. The volume of gas hydrates that underlie the Arctic Ocean seabed is estimated to be 2,000 Gt of CH4 (Makogon et al., 2007). About 85% of the Arctic Ocean sedimentary basins occur within the continental shelf; therefore, within the ESAS alone, which comprises ~30% of the area of the Arctic shelf, hydrate deposits could contain ~500 Gt of CH4. An additional two-thirds of that amount (~300 Gt) is stored in the form of free gas (Ginsburg and Soloviev, 1994). Because submarine permafrost is identical to on-land permafrost, the carbon pool held within submarine permafrost can be estimated to include not less than 500 Gt of carbon within a 25-m-thick permafrost body (Zimov et al., 2006). Thus the total amount of carbon preserved within the Arctic continental shelf could total ~1300 Gt of carbon, of which 800 Gt is previously formed CH4 ready to be suddenly released when appropriate pathways develop (Shakhova and ...

In the hay day of 35mm film, the Astronomy magazines used to have ads for gear and materials that hyper-sensitized films for astrophotography. Years ago, I ran across a reference to this technique being used with the glass plates used for serious scientific work at an observatory. Typically, these treatments involved soaking the emulsion in an oxygen free gas (dont remember what gas) at some moderate pressure and a temperature somewhat above room temp. Do any of these techniques have

The petrol engine then uses a tank full of gasoline, a fossil liquid, to propel the car by exploding small drops of it. It is apparently the small explosions that you hear and feel when the engine is running.. The petrol engine consists of literally hundreds of moving parts that must have tolerance of hundredths of a millimeter to function. We begun to understand why it is car repair shops that sell the cars - they might hope for something to break in the car that they can mend?. We asked if the constant sound of the engine -that frankly disturbed us from being able to listen to the radio- could be turned off. But it couldnt. Very distracting.. The seller looked very puzzled at us and explained that it is not possible to refuel gasoline cars at home, and there are no free gas stations. We tried to explain our questions, in case he had misunderstood, but he insisted that you can not. Apparently youhave to several times a month drive to the gas station to recharge your petrol car at extortionate ...

C. Michael Dunham, MD, Amy E. Hutchinson, MD, Michael S. Kavic, MD INTRODUCTION The use of carbon dioxide (CD) pneumoperitoneum (CDP) in the vast majority of general surgery, gynecological, and urological cases is safe. It is readily available and cost effective. CD gas is rapidly absorbed in blood and peritoneum, colorless, does not support combustion, and generally has few systemic side effects in healthy patients. Specifically, CD is relatively benign because most of the gas in the blood is bound to terminal amino groups of hemoglobin or converted to bicarbonate. Although a small portion of CD exists as a gas in the blood, pulmonary exhalation is generally effective. The majority of CD combines with water in red blood cells to form carbonic acid that subsequently dissociates into hydrogen and bicarbonate. The hydrogen ion combines with hemoglobin, and bicarbonate diffuses into the plasma. Functionally, there is an extensive buffering capacity of blood and tissue for CD, and there is rapid secretion

A 50-year-old patient was admitted to the hospital and submitted to a videolaparascopic surgery for cholecystectomy. Anaesthesia and intubation were performed with no problems. Right after the pneumoperitoneum induction, the low VT alarm of the ventilator was activated. The VT was reduced from 500ml to 300ml. The patient was on pressure controlled ventilation mode (PCV) with an inspiratory time of 1.0s.. The ventilator curves correspondents to this episode are shown below.. ...

The individualized goal-directed therapy (IGDT), with focus on level of venous return, will be implemented in two steps in the intervention group. First, preoperative optimizing of venous return will be performed 45 minutes before surgery in a preoperative room with TTE. Second, after induction of anaesthesia perioperative fluid therapy will be guided by utilizing the FloTrac-device.. Preoperative rehydration with 6 ml colloid fluids (Volulyte™, Fresenius Kabi Ab, Sweden) /kg estimated ideal body weight (IBW) will be administrated if low level of venous return is detected by TTE. After a colloid bolus the second TTE is performed to check the level of venous return. If remaining hypovolemia is found additional colloids 3ml/ kg IBW will be given.. In OR, before pneumoperitoneum, prophylactic i.v. antibiotics will be administrated in total 550ml crystalloids (NaCl 0.9%, Fresenius Kabi Ab, Sweden) to all patients. Infusion of buffered glucose solution (25mg/ml, Fresenius Kabi Ab, Sweden) at rate ...
