Abstract
Objective: This study was designed to investigate preoperative anxiety situations and postoperative pain degree in Chinese patients undergoing laparoscopic hysterectomy and to analyze the related factors of preoperative anxiety and the correlation between preoperative anxiety and postoperative pain to provide a reference for effective postoperative analgesia management.Methods: A total of 100 female patients undergoing laparoscopic hysterectomy were enrolled in this study and randomly divided into two groups (n = 50, each). In group A, the patients were treated with dexmedetomidine and sufentanil for postoperative analgesia. In group B, the patients were treated with sufentanil alone for postoperative analgesia. All patients were evaluated with a self-rating anxiety scale (SAS) 1 day before the operation. The patients’ pain was evaluated using the numerical rating scale (NRS) 1 day after the operation, and data were recorded.Results: In these 100 patients, the highest preoperative SAS score was 48, and the average score was 40.99 ± 4.55 points, which is higher than the norm in China. There were significant differences in preoperative SAS scores among patients with different occupations and previous surgical experience (P < 0.05). There was no significant difference in SAS scores among patients with different education levels (P > 0.05). The postoperative NRS score of group A was significantly higher than that of group B, and the difference was statistically significant (P < 0.05). The correlation coefficients between SAS scores and NRS scores in groups A and B were 0.836 and 0.870, respectively, presenting with a significantly positive correlation.Conclusion: Preoperative anxiety is an important predictor of postoperative pain. Patients undergoing laparoscopic hysterectomy have preoperative anxiety. The degree of anxiety is influenced by the occupation and previous operation experience of the patients, and patients with higher preoperative anxiety have greater postoperative pain. In addition, we should not neglect the management of postoperative pain because of the small trauma of laparoscopic surgery, and dexmedetomidine combined with sufentanil can improve the postoperative analgesic effect.
Highlights
Anxiety as a disorder is defined as a neurosis characterized by anxious overconcern extending to panic and frequently associated with somatic symptoms (Zung, 1971)
Previous studies revealed that the incidence of preoperative anxiety in patients with an elective surgery is high, and female patients are more prone to anxiety (Gan et al, 2014; Mimic et al, 2018)
The exclusion criteria were patients with chronic pain, malignant tumors, and severe complications. These patients were randomly divided into two groups: dexmedetomidine postoperative analgesia pump group and sufentanil postoperative analgesia pump group, with 50 patients in each group
Summary
Anxiety as a disorder is defined as a neurosis characterized by anxious overconcern extending to panic and frequently associated with somatic symptoms (Zung, 1971). Anxiety disorder is considered a common mental disease (Pan et al, 2019). According to the China Mental Health Survey (Huang et al, 2019), the prevalence of anxiety disorder in Chinese patients is 7.6%. Previous studies revealed that the incidence of preoperative anxiety in patients with an elective surgery is high, and female patients are more prone to anxiety (Gan et al, 2014; Mimic et al, 2018). As early as the 1980s, studies revealed that the more anxious the emotion was, the lower the pain threshold of the body (Scott et al, 1983; Johnston, 1986; Browne, 2013). Other studies have revealed that for different types of surgery, preoperative anxiety has different impacts on postoperative pain (Pinto et al, 2015). We started this study to explore the correlation between the two further
