intraop estimated blood loss estimation vs change in hematocrit

BACKGROUND: Previous studies have reported that laparoscopic distal pancreatectomy (LDP) has an advantage in reducing blood loss over open distal pancreatectomy (ODP). This study was performed to investigate whether blood loss is truly reduced in LDP. METHODS: A total of 113 patients undergoing DP from 2014 to 2022 were classified into Open and LDP groups and compared by statistical analysis. Estimated blood loss (EBL) was calculated from the perioperative changes in the hematocrit, hemoglobin, or red blood cell volume, and actual blood loss (ABL) was taken from the operative record...

OBJECTIVES: The association between ibuprofen use and severity of post-tonsillectomy hemorrhage (PTH) remains unclear. We aimed to compare PTH severity in patients who did or did not receive ibuprofen. METHODS: A retrospective cohort study of pediatric patients requiring operative control of PTH at a tertiary children's hospital between 2015 and 2019 was performed. PTH severity was assessed using pre-tonsillectomy and post-hemorrhage hemoglobin and hematocrit values, estimated intraoperative blood loss, estimated hemorrhage flow rate, and need for transfusion...

The study aimed at comparing the safety outcomes between conventional bicoronal and direct method in device removal after cranial distraction in the treatment of craniosynostosis. This was a retrospective cohort study of patients treated with distraction osteogenesis to expand intracranial volume in the anteroposterior direction. Preoperative patient demographics, distraction protocols, and perioperative outcomes (operative time, estimated blood loss, intraoperative fluid volume, lowest hematocrit during surgery, transfusion, hospital stay, drain, postoperative complication) were collected and analyzed with the independent samples t-test...

BACKGROUND: Tranexamic acid (TXA) is a medication that has been shown to decrease blood loss and risk of blood transfusion in total knee and total hip arthroplasty. The purpose of this study was to evaluate the use of TXA in patients undergoing total ankle arthroplasty (TAA). We hypothesized there would be less blood loss and wound complications in patients receiving TXA. METHODS: A retrospective review of 2 patient cohorts operated on by 2 surgeons was performed from 2010 to 2018...

OBJECTIVE: Assess the efficacy and safety of carbetocin, versus oxytocin in the prevention of postpartum hemorrhage in hypertensive women. STUDY DESIGN: A randomized clinical trial. SETTING: Obstetrics and Gynecology Department of Suez Canal University Hospital. PATIENTS: One hundred and sixty hypertensive pregnant women who underwent CS. INTERVENTIONS: Patients were randomized to receive either 10 IU oxytocin or 100 μg carbetocin...

Objective: To compare the effectiveness of perioperative vaginal misoprostol with intraoperative pericervical hemostatic tourniquet in reducing blood loss during abdominal myomectomy. Material and Methods: A randomized controlled trial involving women with uterine leiomyoma who underwent abdominal myomectomy was conducted at a tertiary facility in Nigeria. Participants were recruited after they gave informed consent and randomized into group I (single dose 400 μg vaginal misoprostol one-hour before surgery) and group II (intraoperative pericervical hemostatic tourniquet)...

BACKGROUND: Patient-specific instruments (PSIs) were developed to improve mechanical axis alignment for patients undergoing total knee arthroplasty (TKA) as neutral alignment (180°) is a predictor of long-term success. This study examines alignment accuracy and functional outcomes of PSI as compared with standard instruments (SIs). METHODS: We retrospectively reviewed a consecutive series of TKA procedures using PSI. A total of 85 PSI procedures were identified, and these were compared with a matched cohort of 85 TKAs using SI...

BACKGROUND: Less intraoperative blood loss is frequently reported as an advantage of laparoscopic hepatectomy (LH) over open hepatectomy (OH). However, the small work space during laparoscopic surgery could lead to insufficient blood suction from the abdominal cavity, with possible underestimation of intraoperative blood loss. This study compared estimated blood loss (E-BL) with intraoperatively counted blood loss (IC-BL) in patients undergoing LH. METHODS: This study included 110 consecutive patients undergoing partial hepatectomy for solitary liver tumors (59 had OH and 51 had LH)...

BACKGROUND: The association between preoperative aspirin use and postoperative acute kidney injury (AKI) in cardiovascular surgery is unclear. We sought to evaluate the effect of preoperative aspirin use on postoperative AKI in cardiac surgery. METHODS: A total of 770 patients who underwent cardiovascular surgery under cardiopulmonary bypass were reviewed. Perioperative clinical parameters including preoperative aspirin administration were retrieved. We matched 108 patients who took preoperative aspirin continuously with patients who stopped aspirin more than 7 days or did not take aspirin for the month before surgery...

INTRODUCTION: Endoscopic sinus surgery is a common procedure performed by otolaryngologists. This study evaluated the efficacy of intravenous (IV) tranexamic acid (TA) on hemorrhage in patients undergoing elective endoscopic sinus surgery (ESS). MATERIALS AND METHODS: The present study was performed in 170 patients scheduled for ESS surgery under general anesthesia in order to examine the effects of IV TA on providing a bloodless surgical field and to evaluate the amount of bleeding...

INTRODUCTION: The traditional assessment of blood loss during laparoscopic radical prostatectomy (LRP) is based on the blood volume collected intraoperatively in the suction device bottles. While this method is not perfect, analysis of changes in blood cell count (BCC) resulting from LRP is advisable. MATERIAL AND METHODS: 71 men were submitted to LRP due to prostate cancer in our institution over an 18-month time period. From this group, we isolated 60 men with clinically minimal intraoperative blood loss (<200 ml) and included them into the study...

BACKGROUND: Conventional laparoscopic nephrectomy (LN) is the gold standard approach for nephrectomy. An advance in minimally invasive nephrectomy is laparoendoscopic single-site nephrectomy (LESS-N). OBJECTIVE: To compare 5-yr experience and outcomes of LESS-N to LN. DESIGN, SETTING, AND PARTICIPANTS: Retrospective, case-control, single-surgeon series of 47 LESS-N cases matched in a 1:2 fashion by age, indication, and tumor size to 94 LN controls...

OBJECTIVE: Blunt vs sharp expansion of the uterine incision at cesarean delivery has been investigated as a technique primarily to reduce intraoperative blood loss. The objective of this systematic review was to compare the effects of either intervention on maternal outcomes. STUDY DESIGN: A systematic review with metaanalyses that used the DerSimonian and Laird random effects model was performed. The Cochrane Central Register of Controlled Trials (The Cochrane Library 2012, Issue 4), MEDLINE (1948-Apr 2012), EMBASE (1947-Apr 2012), and the reference lists/citation history of articles were searched...

PURPOSE: Radical retropubic prostatectomy (RRP) has been associated with significant blood loss and/or transfusion requirement. While still a concern, routine autologous blood donation has not been standard at our institution for more than a decade. We assessed recent blood loss and transfusion requirements in contemporary patients undergoing RRP and examined the possible predictive impact of preoperative variables. MATERIALS AND METHODS: A retrospective review of 436 consecutive patients who underwent RRP between July 1999 and December 2001 was performed with the primary purpose of analyzing estimated blood loss (EBL) and blood transfusion requirements as well as possible preoperative risk factors, including clinical demographic characteristics, body mass index (BMI), defined as weight in kg/height in m, comorbidities, American Society of Anesthesiologists classification and Charlson index score...

The purpose of this study was to assess the accuracy of estimated blood loss (EBL) as a reliable predictor of actual blood loss during orthopedic procedures. Between 1999 and 2002, 198 orthopedic cases were reviewed. A retrospective review compiled preoperative and postoperative demographic and laboratory data from the surgical patients. Estimated blood loss data was collected from the perioperative and anesthesia reports. Statistical analysis of EBL vs. change in hemoglobin yielded a correlation coefficient of 0...

OBJECTIVE: The mechanism for the initiation of human labor remains unknown and is under extensive investigation. Myometrium from patients in labor and not in labor is the ideal tissue to study structural, cellular, and molecular changes that occur during parturition. This study was designed to determine whether myometrial sampling at the time of cesarean delivery increases maternal morbidity. STUDY DESIGN: This is a prospective cohort study including 118 study and 236 control patients...

STUDY DESIGN: One hundred five patients with adolescent idiopathic scoliosis who underwent posterior spinal instrumentation and fusion with predeposited autologous blood, with or without intraoperative autologous transfusion, were reviewed. OBJECTIVE: To determine the benefit/nonbenefit of intraoperative autologous transfusion in diminishing the need for homologous blood and influencing post-operative hematocrit values in healthy adolescents undergoing spinal fusion for scoliosis...
