Effect of Intraspinal Anesthesia on Postoperative Recovery in Elderly Patients with Acute Appendicitis: A...

Acute appendicitis is a common disease in the elderly. Exploring a suitable anesthesia method is crucial in promoting postoperative recovery in elderly patients. Therefore, this study aimed to investigate the clinical effect of intraspinal anesthesia in elderly patients with appendicitis.

This study included the clinical data of 217 elderly patients with acute appendicitis who underwent laparoscopic appendectomy (LA) at Tianjin Hospital of Tianjin University from January 2022 to January 2023. After excluding 8 patients who did not meet the inclusion criteria, the data from 209 patients were retrospectively analyzed. Based on the different anesthesia methods, the study participants were divided into a reference group (n = 106) and a study group (n = 103). We compared the heart rate (HR), respiratory rate (RR), systolic blood pressure (SBP), diastolic blood pressure (DBP), blood oxygen saturation (SaO2), operation duration, hospitalization costs, discharge time, postoperative adverse reactions, inflammatory factor levels, Visual Analogue Scale (VAS) score, recovery time of intestinal peristalsis, anal exsufflation time, out-of-bed time, and incidence of postoperative complications between the two experimental groups.

We observed that the study group exhibited higher levels of HR, RR, SBP, DBP, and SaO2 compared to the reference group (p < 0.001). However, there was no difference in operation time between the two groups (p > 0.05). The study group showed lower hospitalization cost and shorter discharge time than the reference group (p < 0.001). Similarly, the study group had lower incidence of postoperative adverse reactions than reference group (p < 0.05). There were no significant differences in the levels of C-reactive protein, interleukin-6, and tumor necrosis factor-α between the two groups before and after surgery (p > 0.05). Furthermore, the study group had a lower VAS score compared to the reference group at 3 h, 6 h and 12 h after surgery (p < 0.001). The recovery time of intestinal peristalsis, anal exsufflation time, and out-of-bed time in the study group were substantially shorter than the reference group (p < 0.001). Additionally, there was no difference in the incidence of postoperative complications between the two groups within 1 year after surgery (p < 0.001).

Intraspinal anesthesia, as a safe anesthesia method, can reduce the discharge time of elderly patients with acute appendicitis who underwent LA, and reduce the occurrence of adverse reactions, and is beneficial for postoperative recovery.
