| Summary: | Abstract
Background:
Preoperative anxiety is a common phenomenon affecting 60–80% of surgical patients, with potential implications for surgical outcomes. Despite its prevalence, there remains a lack of consensus on its precise effects and optimal management strategies.
Objective:
This meta-analysis aimed to synthesize current evidence on the impact of preoperative anxiety on various surgical outcomes, including anesthetic and analgesic requirements, delirium, recovery times, and pain.
Methods:
We conducted a comprehensive literature search and meta-analysis of studies examining the relationship between preoperative anxiety and surgical outcomes. Standardized mean differences (SMD), correlation (COR), and odds ratios (OR) with 95% confidence intervals were calculated.
Results:
Our analysis revealed significant associations between preoperative anxiety and increased anesthetic requirements (SMD = 0.67, 95% CI: 0.32–1.01) and analgesic requirements (SMD = 0.89, 95% CI: 0.65–1.12). Preoperative anxiety was associated with postoperative delirium in adults (OR = 1.90, 95% CI: 1.11–3.26), unlike the pediatric population. Preoperative anxiety was associated with prolonged time to reach Modified Aldrete Score of 9 (SMD = 0.79, 95% CI: 0.50–1.07) and extubation time (SMD = 0.89, 95% CI: 0.58–1.21). Preoperative anxiety was positively correlated with propofol consumption (STAI-S COR = 0.35, 95%CI: 0.15–0.55). No significant association between preoperative anxiety and postoperative pain was found.
Conclusions:
This meta-analysis provides evidence for the wide-ranging effects of preoperative anxiety on surgical outcomes. The findings emphasize the need for routine preoperative anxiety screening and the development of targeted interventions. Future research should focus on long-term impacts and the effectiveness of various anxiety management strategies.
