PURPOSE: To compare the rate and unit of allogeneic blood transfusion in one-stage bilateral total hip arthroplasty (THA) in patients with and without autologous blood reinfusion. METHODS: Records of a consecutive series of 43 men and 33 women aged 25 to 83 (mean, 55) years who underwent one-stage sequential bilateral THA by a single surgeon were reviewed. Their risks of cardiopulmonary complications were minimal. At least 4 weeks prior to surgery, 38 of the patients donated 2 units of autologous blood in 2 stages (one to 2 weeks apart). The remaining 38 patients did not donate blood owing to personal preferences or logistical reasons. All pre-donated autologous blood was transfused back to the patients in the recovery room. Estimated blood loss volume, blood salvaged volume, and complications were recorded, as were pre- and post-operative haemoglobin levels. The 2 groups were compared with respect to the rate and unit of allogeneic blood transfusion. RESULTS: The mean estimated blood loss was 939 (SD, 448; range, 200-2500) ml. The mean volume of blood salvaged was 302 (SD, 196; range, 0-850) ml, representing a collection rate of 32%. In patients with and without autologous blood reinfusion, 16 (42%) and 33 (87%) patients received allogeneic blood transfusion of 0.9 and 2.4 units, respectively (p<0.0001). Four patients developed major cardiopulmonary complications. None had deep venous thrombosis or pulmonary embolism. No complications resulted from blood transfusion. The 2 groups were not significantly different in complication rate (13% vs. 18%, p=0.54) and discharge haemoglobin levels. CONCLUSION: Autologous blood reinfusion was effective in reducing the rate and unit of allogeneic blood transfusion in patients undergoing one-stage bilateral THA. (+info)Operative blood salvage, also known as intraoperative blood recovery or cell salvage, is a medical procedure that involves the collection, washing, and reinfusion of a patient's own blood during surgery. The blood is collected from the surgical site using a suction device and then processed to remove any debris, clots, and free hemoglobin. The resulting red blood cells are then washed and suspended in a sterile solution before being returned to the patient through a transfusion.
This technique is commonly used during surgeries where significant blood loss is expected, such as orthopedic, cardiovascular, and major cancer surgeries. It offers several advantages over allogeneic (donor) blood transfusions, including reduced exposure to potential transfusion reactions, decreased risk of infectious disease transmission, and lower costs. However, it may not be appropriate for all patients or surgical procedures, and its use should be carefully considered based on the individual patient's medical history and condition.
Autologous blood transfusion is a medical procedure in which a patient receives their own blood that has been collected and stored prior to surgery or a medical treatment that may cause significant blood loss. The blood is drawn from the patient, typically in the days or weeks leading up to the scheduled procedure, and then stored until it is needed during or after the surgery.
The primary advantage of autologous blood transfusion is that it eliminates the risk of transfusion reactions, infectious disease transmission, and immunomodulation associated with allogeneic (donor) blood transfusions. However, not all patients are candidates for this type of transfusion due to various factors such as medical conditions, low hemoglobin levels, or insufficient time to collect and store the blood before the procedure.
Autologous blood transfusion can be performed using several methods, including preoperative blood donation, acute normovolemic hemodilution, intraoperative cell salvage, and postoperative blood collection. The choice of method depends on various factors, such as the patient's medical condition, the type and extent of surgery, and the availability of resources.
In summary, autologous blood transfusion is a safe and effective way to reduce the need for allogeneic blood transfusions during or after surgical procedures, but it may not be suitable for all patients.
Surgical blood loss is the amount of blood that is lost during a surgical procedure. It can occur through various routes such as incisions, punctures or during the removal of organs or tissues. The amount of blood loss can vary widely depending on the type and complexity of the surgery being performed.
Surgical blood loss can be classified into three categories:
1. Insensible losses: These are small amounts of blood that are lost through the skin, respiratory tract, or gastrointestinal tract during surgery. They are not usually significant enough to cause any clinical effects.
2. Visible losses: These are larger amounts of blood that can be seen and measured directly during surgery. They may require transfusion or other interventions to prevent hypovolemia (low blood volume) and its complications.
3. Hidden losses: These are internal bleeding that cannot be easily seen or measured during surgery. They can occur in the abdominal cavity, retroperitoneal space, or other areas of the body. They may require further exploration or imaging studies to diagnose and manage.
Surgical blood loss can lead to several complications such as hypovolemia, anemia, coagulopathy (disorders of blood clotting), and organ dysfunction. Therefore, it is essential to monitor and manage surgical blood loss effectively to ensure optimal patient outcomes.
Intraoperative care refers to the medical care and interventions provided to a patient during a surgical procedure. This care is typically administered by a team of healthcare professionals, including anesthesiologists, surgeons, nurses, and other specialists as needed. The goal of intraoperative care is to maintain the patient's physiological stability throughout the surgery, minimize complications, and ensure the best possible outcome.
Intraoperative care may include:
1. Anesthesia management: Administering and monitoring anesthetic drugs to keep the patient unconscious and free from pain during the surgery.
2. Monitoring vital signs: Continuously tracking the patient's heart rate, blood pressure, oxygen saturation, body temperature, and other key physiological parameters to ensure they remain within normal ranges.
3. Fluid and blood product administration: Maintaining adequate intravascular volume and oxygen-carrying capacity through the infusion of fluids and blood products as needed.
4. Intraoperative imaging: Utilizing real-time imaging techniques, such as X-ray, ultrasound, or CT scans, to guide the surgical procedure and ensure accurate placement of implants or other devices.
5. Neuromonitoring: Using electrophysiological methods to monitor the functional integrity of nerves and neural structures during surgery, particularly in procedures involving the brain, spine, or peripheral nerves.
6. Intraoperative medication management: Administering various medications as needed for pain control, infection prophylaxis, or the treatment of medical conditions that may arise during the surgery.
7. Temperature management: Regulating the patient's body temperature to prevent hypothermia or hyperthermia, which can have adverse effects on surgical outcomes and overall patient health.
8. Communication and coordination: Ensuring effective communication among the members of the surgical team to optimize patient care and safety.
Salvage therapy, in the context of medical oncology, refers to the use of treatments that are typically considered less desirable or more aggressive, often due to greater side effects or lower efficacy, when standard treatment options have failed. These therapies are used to attempt to salvage a response or delay disease progression in patients with refractory or relapsed cancers.
In other words, salvage therapy is a last-resort treatment approach for patients who have not responded to first-line or subsequent lines of therapy. It may involve the use of different drug combinations, higher doses of chemotherapy, immunotherapy, targeted therapy, or radiation therapy. The goal of salvage therapy is to extend survival, improve quality of life, or achieve disease stabilization in patients with limited treatment options.
Intraoperative complications refer to any unforeseen problems or events that occur during the course of a surgical procedure, once it has begun and before it is completed. These complications can range from minor issues, such as bleeding or an adverse reaction to anesthesia, to major complications that can significantly impact the patient's health and prognosis.
Examples of intraoperative complications include:
1. Bleeding (hemorrhage) - This can occur due to various reasons such as injury to blood vessels or organs during surgery.
2. Infection - Surgical site infections can develop if the surgical area becomes contaminated during the procedure.
3. Anesthesia-related complications - These include adverse reactions to anesthesia, difficulty maintaining the patient's airway, or cardiovascular instability.
4. Organ injury - Accidental damage to surrounding organs can occur during surgery, leading to potential long-term consequences.
5. Equipment failure - Malfunctioning surgical equipment can lead to complications and compromise the safety of the procedure.
6. Allergic reactions - Patients may have allergies to certain medications or materials used during surgery, causing an adverse reaction.
7. Prolonged operative time - Complications may arise if a surgical procedure takes longer than expected, leading to increased risk of infection and other issues.
Intraoperative complications require prompt identification and management by the surgical team to minimize their impact on the patient's health and recovery.
Postoperative complications refer to any unfavorable condition or event that occurs during the recovery period after a surgical procedure. These complications can vary in severity and may include, but are not limited to:
1. Infection: This can occur at the site of the incision or inside the body, such as pneumonia or urinary tract infection.
2. Bleeding: Excessive bleeding (hemorrhage) can lead to a drop in blood pressure and may require further surgical intervention.
3. Blood clots: These can form in the deep veins of the legs (deep vein thrombosis) and can potentially travel to the lungs (pulmonary embolism).
4. Wound dehiscence: This is when the surgical wound opens up, which can lead to infection and further complications.
5. Pulmonary issues: These include atelectasis (collapsed lung), pneumonia, or respiratory failure.
6. Cardiovascular problems: These include abnormal heart rhythms (arrhythmias), heart attack, or stroke.
7. Renal failure: This can occur due to various reasons such as dehydration, blood loss, or the use of certain medications.
8. Pain management issues: Inadequate pain control can lead to increased stress, anxiety, and decreased mobility.
9. Nausea and vomiting: These can be caused by anesthesia, opioid pain medication, or other factors.
10. Delirium: This is a state of confusion and disorientation that can occur in the elderly or those with certain medical conditions.
Prompt identification and management of these complications are crucial to ensure the best possible outcome for the patient.
Laparoscopy is a surgical procedure that involves the insertion of a laparoscope, which is a thin tube with a light and camera attached to it, through small incisions in the abdomen. This allows the surgeon to view the internal organs without making large incisions. It's commonly used to diagnose and treat various conditions such as endometriosis, ovarian cysts, infertility, and appendicitis. The advantages of laparoscopy over traditional open surgery include smaller incisions, less pain, shorter hospital stays, and quicker recovery times.
A blood transfusion is a medical procedure in which blood or its components are transferred from one individual (donor) to another (recipient) through a vein. The donated blood can be fresh whole blood, packed red blood cells, platelets, plasma, or cryoprecipitate, depending on the recipient's needs. Blood transfusions are performed to replace lost blood due to severe bleeding, treat anemia, support patients undergoing major surgeries, or manage various medical conditions such as hemophilia, thalassemia, and leukemia. The donated blood must be carefully cross-matched with the recipient's blood type to minimize the risk of transfusion reactions.
"Length of Stay" (LOS) is a term commonly used in healthcare to refer to the amount of time a patient spends receiving care in a hospital, clinic, or other healthcare facility. It is typically measured in hours, days, or weeks and can be used as a metric for various purposes such as resource planning, quality assessment, and reimbursement. The length of stay can vary depending on the type of illness or injury, the severity of the condition, the patient's response to treatment, and other factors. It is an important consideration in healthcare management and can have significant implications for both patients and providers.
Limb salvage is a medical term used to describe the surgical procedures and treatments aimed at preserving and restoring the functionality of a severely injured or diseased limb, rather than amputating it. The goal of limb salvage is to improve the patient's quality of life by maintaining their mobility, independence, and overall well-being.
Limb salvage may involve various surgical techniques such as vascular reconstruction, bone realignment, muscle flap coverage, and external fixation. These procedures aim to restore blood flow, stabilize bones, cover exposed tissues, and prevent infection. Additionally, adjuvant therapies like hyperbaric oxygen treatment, physical therapy, and pain management may be employed to support the healing process and improve functional outcomes.
Limb salvage is typically considered when a limb is threatened by conditions such as severe trauma, tumors, infections, or peripheral arterial disease. The decision to pursue limb salvage over amputation depends on factors like the patient's overall health, age, and personal preferences, as well as the extent of the injury or disease, potential for recovery, and likelihood of successful rehabilitation.
Treatment outcome is a term used to describe the result or effect of medical treatment on a patient's health status. It can be measured in various ways, such as through symptoms improvement, disease remission, reduced disability, improved quality of life, or survival rates. The treatment outcome helps healthcare providers evaluate the effectiveness of a particular treatment plan and make informed decisions about future care. It is also used in clinical research to compare the efficacy of different treatments and improve patient care.
Retrospective studies, also known as retrospective research or looking back studies, are a type of observational study that examines data from the past to draw conclusions about possible causal relationships between risk factors and outcomes. In these studies, researchers analyze existing records, medical charts, or previously collected data to test a hypothesis or answer a specific research question.
Retrospective studies can be useful for generating hypotheses and identifying trends, but they have limitations compared to prospective studies, which follow participants forward in time from exposure to outcome. Retrospective studies are subject to biases such as recall bias, selection bias, and information bias, which can affect the validity of the results. Therefore, retrospective studies should be interpreted with caution and used primarily to generate hypotheses for further testing in prospective studies.
