intraop estimated blood loss estimation vs change in hematocrit

Yoshito Tomimaru, Kozo Noguchi, Shunji Morita, Hiroshi Imamura, Takashi Iwazawa, Keizo Dono
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...
