Postoperative anaemia is associated with increased postoperative morbidity. The optimal timing for postoperative packed cell volume (PCV) assessment remains unclear and varies across surgical units.
This study compared PCV values on postoperative days 1 and 2 to determine their relationship with the expected postoperative PCV.
A cross-sectional study was conducted among patients who had elective gynaecological surgeries at a tertiary Hospital in Southern Nigeria. PCV was measured preoperatively and at 24 and 48 hours postoperatively. Data on intraoperative blood loss, type of surgery, and anaesthesia were recorded.
The mean PCV on postoperative day 1 was 30.87 ± 3.85%, while on day 2, it was 30.33 ± 3.70%, with a significant difference (p = 0.005). The expected postoperative PCV was 31.02 ± 2.68%. The difference between day 1 PCV and the expected PCV was not statistically significant (p = 0.682). Similarly, the day 2 PCV was not significantly different from the expected value (p = 0.064).
Although a significant decline in PCV occurred between postoperative days 1 and 2, the day 1 PCV was closer to the expected postoperative value. This suggests that day 1 may be a more reliable time for routine PCV monitoring after gynaecological surgeries.
术后贫血与术后发病率增加有关。术后血细胞比容（PCV）评估的最佳时机仍不明确，且各手术科室有所不同。
本研究比较术后第1天和第2天的PCV值，以确定它们与预期术后PCV的关系。
在尼日利亚南部一家三级医院对接受择期妇科手术的患者进行了一项横断面研究。术前以及术后24小时和48小时测量PCV。记录术中失血量、手术类型和麻醉情况。
术后第1天的平均PCV为30.87±3.85%，而第2天为30.33±3.70%，差异有统计学意义（p = 0.005）。预期术后PCV为31.02±2.68%。第1天PCV与预期PCV之间的差异无统计学意义（p = 0.682）。同样，第2天PCV与预期值无显著差异（p = 0.064）。
虽然术后第1天和第2天之间PCV出现了显著下降，但第1天的PCV更接近预期术后值。这表明术后第1天可能是妇科手术后常规PCV监测更可靠的时间。
