Key result
Hypotension occurred in 56.8% of emergency cesarean sections under spinal anaesthesia, with significant risk factors including baseline SBP <120 mmHg (AOR 3.60) and absence of spinal additives.
Why the study?
Hypotension is a common incidental complication after subarachnoid block in emergency cesarean section, motivating an evaluation of its incidence and associated factors.

What are the incidence and factors associated with hypotension in emergency patients undergoing cesarean section with spinal anaesthesia?
Hypotension is highly prevalent (56.8%) during emergency cesarean section under spinal anesthesia, with modifiable risk factors including the use of spinal additives, timing of crystalloid loading, and injection speed.
Supports targeted monitoring for hypotension in emergency cesarean sections under spinal; leaves open optimal prevention strategies.
Background: Hypotension is the common incidental complication after subarachnoid block in emergency cesarean section. This study aimed to identify incidence and factors associated with hypotension in emergency cesarean section that underwent spinal anaesthesia. Methods: Prospective observational study was done with statistical analysis of SPSS version 20. Binary logistic regression analysis was performed to determine whether each of independent variables was associated or not with the outcome variables. Both Crude and Adjusted Odds Ratio were calculated to show strength of association. Variables with P-value of <0.05 were considered to be statistically significant. Results: Incidence of hypotension in emergency cesarean section was 56.8% (95% CI; 50.2–63.4). Baseline systolic blood pressure <120 mmhg (AOR, 3.60 95% CI; 1.26–10.31), absence of spinal additives (AOR, 5.08, 95% CI; 1.78–14.48), duration of crystalloid load before 20 min (AOR, 27.9, 95% CI; 8.3–93.6) and speed of injection < 10 s (AOR, 4.47, 95% CI; 1.14–17.62) were significantly associated with hypotension. Conclusion: The incidence of hypotension was high. Baseline blood pressure, spinal additives, duration of crystalloid load and speed of injection were significantly associated with hypotension. So, we recommend considering spinal additives, fluid co-loading and slow injection of drugs to reduce incidence of hypotension. Highlights

Chekol et al. (2021) conducted an observational in Emergency cesarean section with spinal anaesthesia. Risk factors for hypotension (e.g., baseline SBP <120 mmHg, absence of spinal additives) vs. Absence of risk factors was evaluated on Incidence of hypotension (95% CI 50.2-63.4). Hypotension occurred in 56.8% of emergency cesarean sections under spinal anaesthesia, with significant risk factors including baseline SBP <120 mmHg (AOR 3.60) and absence of spinal additives.
