Caesarean Section (CS) is a mode of delivery to decrease maternal and perinatal morbidity and mortality. We aimed to determine the type of anaesthesia used for CS among live-birth deliveries; and the failure rate of spinal anaesthesia (SA) in Princess Marina Referral Hospital, Botswana.
Women who underwent CS from May-December 2017 were enrolled in the study. Data were recorded from anaesthesia charts and abstracted using Excel spreadsheet. We established the type of anaesthesia used, comparing the rate of elective versus emergency indications, and failure rate of SA using STATA. Fisher's exact test used to compare results.
Among 2775 live-birth deliveries, 30.2% (837/2775) was by CS. Of those, 95.2% (797/837) had had SA and 4.8% (40/837) were GA. Under SA, 27.4% (218/797) were elective, and 72.6% (579/797) were emergency. Under GA 10% (4/40) were elective and 90.0% (36/40) were emergency. The overall failure rate of SA was 2% (16/813), that is 0.9% (2/220) for elective and 2.4% (14/593) among emergency indications; Fisher's exact test p = 0.2959.
Our study demonstrated that single shot SA is the most commonly preferred type of anaesthesia for both elective and emergency CS. The overall failure rate of SA was less common in our settings than previously reported.
剖宫产术（CS）是一种降低母婴围产期发病率和死亡率的分娩方式。我们旨在确定博茨瓦纳马里纳公主转诊医院活产分娩中使用的麻醉类型；以及脊髓麻醉（SA）的失败率。
本研究纳入了 2017 年 5 月至 12 月期间行 CS 的女性。数据从麻醉图表中记录，并使用 Excel 电子表格进行提取。我们确定了使用的麻醉类型，比较了择期与紧急指征的比率，以及 SA 的失败率，使用 STATA 进行分析。Fisher 确切检验用于比较结果。
在 2775 例活产分娩中，30.2%（837/2775）为 CS。其中，95.2%（797/837）接受了 SA，4.8%（40/837）为 GA。在 SA 下，27.4%（218/797）为择期，72.6%（579/797）为紧急。在 GA 下，10%（4/40）为择期，90.0%（36/40）为紧急。SA 的总体失败率为 2%（16/813），即择期为 0.9%（2/220），紧急为 2.4%（14/593）；Fisher 确切检验 p = 0.2959。
我们的研究表明，单次 SA 是择期和紧急 CS 最常用的麻醉类型。在我们的环境中，SA 的总体失败率低于先前的报道。
