# Spinal Versus General Anesthesia for Lumbar Discectomy: Patient-Centered Analysis of Satisfaction with Anesthesia Service

## TL;DR

The study found no significant difference in patient satisfaction between spinal and general anesthesia for lumbar disc surgery, highlighting the importance of managing anxiety and postoperative pain.

## Contribution

This study provides novel insights into patient satisfaction with anesthesia services in lumbar discectomy, emphasizing non-anesthesia-related factors like anxiety and postoperative discomfort.

## Key findings

- Patient satisfaction scores were high and similar between spinal and general anesthesia groups.
- Anxiety and postoperative pain were key factors affecting patient satisfaction.
- Oropharyngeal discomfort was more common with general anesthesia.

## Abstract

Background and Objectives: Spinal (SA) and general anesthesia (GA) are both available for lumbar disc hernia (LDH) surgery. Patient satisfaction with anesthesia service is under-investigated and may help identify areas requiring improvement, leading to better care. Materials and Methods: A prospective, non-randomized, survey-based study was performed in patients who underwent LDH surgeries under SA or GA. Patients rated perioperative pain (preoperative and postoperative days (PODs) 0, 1, and 2) and satisfaction with perioperative care (10 questions) on a numeric rating scale (NRS) from 0 to 10, and an overall satisfaction score (OSS) was calculated; a patient discomfort questionnaire was also used. Study outcomes were pain scores, satisfaction with care, and discomfort reported by SA and GA patients. Results: In total, 209 completed questionnaires in the GA and SA groups (114 vs. 95) were available for final analysis. Baseline characteristics did not differ significantly between the two groups. The proportion of patients with severe pain decreased from >80% preoperatively to 6% on POD2, and pain scores did not differ significantly between groups. Mean overall satisfaction scores (OSSs) were high: 9.71 (maximum OSS: 57% of cases) in the GA group, and 9.75 (maximum OSS: 53.7% of cases) in the SA group (p = 0.95). The ceiling effect of the patient satisfaction questionnaire had to be addressed. There was no association between the type of anesthesia and OSS. Sources of discomfort were similar between groups, except for oropharyngeal discomfort being more prevalent in the GA group (p < 0.05). Postoperative pain was reported as a source of discomfort by >50% of patients in both the SA and GA groups. Regression analysis identified anxiety and nude body exposure as preoperative factors associated with decreased satisfaction with anesthesia. Postoperative factors associated with submaximal satisfaction were PONV, cold, mouth dryness, and pain. Pain on POD 0 did not influence overall patient satisfaction. An association was only found when pain persisted on POD 1 and POD 2. Conclusions: No significant differences between the two anesthesia methods were found. Patient information, anxiety management, and privacy protection are important for patient satisfaction. In the postoperative period, pain and PONV management must be equally addressed, irrespective of the anesthesia method used. Further efforts to develop optimal tools for patient satisfaction assessment are necessary.
