The Effect of Prolonged Fasting Before Surgery on Pain and Anxiety.

Abstract

Purpose: To investigate the effect of prolonged fasting before surgery on pain and anxiety.

Design: This was a descriptive study.

Methods: This study was conducted in a plastic, reconstructive, and esthetic surgery clinic at a university hospital in Bursa, Turkey. A data collection tool was designed to collect data on the sociodemographic characteristics. The Beck Anxiety Scale was used to assess patients' anxiety in the preoperative period and the Visual Analog Scale was used to measure pain levels in the postoperative period. The Statistical Package for Social Sciences was used for data analysis.

Findings: A total of 363 patients took part in the study. A majority (91.2%) of the patients who participated in the study were aware of why they were fasting before surgery, and 41.6% of them had been informed about preoperative fasting by the nurse. In addition, 60.9% of patients had thirst, 17.6% had headache, 40.5% were hungry, 62% had dry mouth, 79.6% were restless, and 83.7% were anxious. Most (82.6%) of the patients who participated in the study had a preoperative fasting period of more than 6 hours, 58.4% had a postoperative fasting period of 5 hours or less, and the mean fasting period was 6.82 ± 1.76. The mean score of the Visual Comparison Scale was 5.09 ± 0.31 and the mean score of the Beck Anxiety Scale was 21.86 ± 0.054, and patients with a fasting period of 6 hours or more experienced more pain and anxiety.

Conclusions: This study shows that patients with longer fasting duration experience more pain and anxiety, and patients with more anxiety experience more pain. Based on the results of this study, it is recommended that studies should be done to emphasize the issue and to increase the awareness of health care professionals about pre- and postoperative fasting.
