Abstract

Background: Elective Gynecologic surgery involves many techniques and often necessitates blood transfusion. Blood preparation and blood use therefore vary according to type of operation. Objective: To study the crossmatch to transfusion ratio C:T ratio in patients undergoing elective gynecological surgery at Vachira Phuket Hospital and analysis factors associated with perioperative blood transfusion.

Materials and Methods: The retrospectively reviewed anesthetic records of 400 gynecologic surgeries from October 2021 to September 2023. Data collection included unit of PRC preparation and transfusion, comorbid conditions, preoperative hemoglobin level, diagnosis, type of surgery, operative time, intraoperative blood loss, Analysis with crossmatch to transfusion ratio (C:T ratio), transfusion probability (%T) and transfusion index (Ti), Chi-square, t-test, Odds ratio, 95% CI and multivariate logistic regression, p-value < 0.05 was considered

Results: A total of 400 patients were included, 105 patients received transfusions. Total cross matching PRC 900 Units, Transfused PRC 215 units. The C: T ratio was 4.2 The %T and Ti were 24.3 and 0.5, respectively. Total Laparoscopic Hysterectomy, Laparoscopic staging, and Laparoscopic Surgery had C:T ratio values ​​of 12.5, 11, and 9.5, respectively. Associated factor of perioperative blood transfusion were ASA classification (Adjusted OR = 0.21, 95% CI = 0.07-0.65), Intraoperative hypotension (Adjusted OR = 0.34, 95% CI=0.17-0.70), type of surgery (Adjusted OR = 0.25, 95% CI= 0.14-0.44).

Conclusion: At Vachira Phuket Hospital, elective gynecologic surgeries showed a high C:T ratio, low blood utilization, and low transfusion index. Laparoscopic gynecologic procedures had the highest C:T ratio and the lowest transfusion index among all types, routine crossmatch blood reservation is deemed unnecessary for these procedures.
