Abstract
Background: Spinal anesthesia has been used for cesarean section for a long time. However, the proportion of post-cesarean paturients who were able to sit at the fourth hour still remains unclear. Objective: Investigate the proportion of post-cesarean paturients that were able to sit at the fourth hour following spinal anesthesia with 0.5% hyperbaric bupivacaine and morphine. Furthermore, investigate the optimum time to encourage ambulation, and the risk factors delaying time duration to sit. Methods: A prospective observational study was conducted in 240 patients with American Society of Anesthesiologists physical status classification I and II, and single pregnancy parturients undergoing cesarean section. The patients who had body mass index (BMI) >35, estimated blood loss >1000 mL, needed postoperative bed rest, or received postoperative sedation were excluded. Hyperbaric bupivacaine 8-11 mg and morphine 0.2-0.3 mg were used. The patients were evaluated at the fourth hour until they could sit without adverse events or complete the sixth hour. All patients were evaluated for risk factors delaying the time duration to sit. Results: Out of 240 patients, 77.0%, 90.9%, and 98.4% were able to sit at the fourth, fifth, and sixth hour, respectively. The risk factors that delayed time to sit were Bromage scale >1 and pain score >3 by the univariate analysis, and were Bromage scale >1 and pain score >3 by the multivariate analysis. Conclusion: Seventy-seven percent of the patients could sit at the fourth hour, and most patients (98%) could sit at the sixth hour. The risk factors that delayed the time duration to sit were Bromage score >1 and pain score >3.
