Objective To investigate the early clinical efficacy of a 3D-printed external fixation guide combined with video-assisted thoracic surgery (VATS) in the treatment of flail chest, and to provide evidence for its clinical application. Methods Patients with flail chest admitted to Xiamen University Affiliated Chenggong Hospital between January 2010 and January 2023 were retrospectively selected as the study subjects. Based on the surgical methods, the patients were divided into two groups: patients treated with the 3D-printed external fixation guide combined with VATS were assigned to a 3D group, and those who underwent open reduction and internal fixation were assigned to an internal fixation group. The operative time, intraoperative blood loss, duration of chest tube drainage, recovery of thoracic volume, visual analogue scale (VAS) scores at 1 month postoperatively, and complications were compared between the two groups. Results A total of 40 patients were included, with 20 patients in each group. The 3D group consisted of 13 males and 7 females, with a mean age of (45.7±3.8) years; the internal fixation group consisted of 14 males and 6 females, with a mean age of (47.3±4.1) years. There were no statistical differences between the two groups in terms of gender, age, number of rib fractures, or preoperative VAS scores (P>0.05). The surgeries were performed successfully in both groups, primary wound healing was achieved in all patients, and pain symptoms were significantly alleviated compared to preoperation. No postoperative complications occurred in the 3D group, whereas 1 patient each of chronic postoperative pain, fracture malunion, and incision infection occurred in the internal fixation group, resulting in a complication rate of 15.0%. The operative time, intraoperative blood loss, and duration of chest tube drainage in the 3D group were significantly shorter or less than those in the internal fixation group (P<0.05). There were no statistical differences in the recovery of thoracic volume or the VAS scores at 1 month postoperatively between the two groups (P>0.05). Conclusion The early clinical efficacy of a 3D-printed external fixation guide combined with VATS in the treatment of flail chest is satisfactory. This technique offers the advantages of being minimally invasive, highly efficient, promoting rapid recovery, and resulting in fewer postoperative complications, and can effectively reconstruct the thoracic contour and restore thoracic volume.

Objective: To investigate the clinical significance of scheduled diclofenac sodium in gynecological hysteroscopic surgery. Methods: A total of 125 patients undergoing hysteroscopic surgery were divided into observation group(64 cases) and control group(61 cases) according to the operation date.The observation group received diclofenac sodium(50mg) 30min before operation and after operation.The control group was anesthetized with propofol 2mg·kg^-1·h^-1.The pain at 1h and 2h postoperatively, the incidence of adverse reactions within 12h after operation, the time from operation to bed ambulation, anesthetic cost and comfort of patients were compared between the two groups. Results: The pain scores of VAS in the observation group at 1h and 2h postoperatively were (3.23±1.75)points and (1.84±1.36)points, respectively, which were significantly lower than those in the control group[(5.07±1.73)points and (2.75±1.60)points, t=-5.875, -3.435, all P<0.05]. The incidence of nausea and vomiting in the observation group within 12h after operation was less than that in the control group(5 cases vs.27 cases)(χ²=12.175, P<0.05). The time spent on ambulation of the observation group[(11.17±2.18)min]was significantly shorter than that of the control group[(17.84±3.42)min](t=-12.933, P<0.05). The anesthetic cost of the observation group was significantly lower than that of the control group (1.24 CNY vs.71.30 CNY, t=18.130, P<0.05). Conclusion The diclofenac sodium plan anal preoperative analgesic effect in patients undergoing gynecological hysteroscopic surgery is better, so that out of bed activities ahead of time, can reduce the anesthesia costs, gynecological hysteroscopy can be used as the preferred method of anesthesia.

Objective To explore the effect of quality nursing intervention on reproductive function in patients with intrauterine adhesions.Methods A total of 626 patients with infertility treated with hysteroscopy in our hospital were divided into two groups according to random number table method,with 313 cases in each group.The patients in the control group were given routine nursing measures,while the patients in the observation group were given high quality nursing intervention on the basis of control group.The reproductive function indexes and complications of the two groups were statistically analyzed and compared.Results Before intervention,the levels of E2 in two groups showed no significant differences (P ＞ 0.05).After intervention,the levels of E2 were both improved,and the observation group was higher than the control group (P ＜0.05).There were 216 cases (69.01％) with normal menstrual recovery,which was significantly higher than 153 cases in the control group (P ＜ 0.05);The incidence of complications in the observation group was 1.60％ (5/313),which was significantly lower than 6.39％ (20/313) in the control group (P ＜ 0.05).Conclusion Quality nursing intervention,with obvious efficacy,can improve reproductive function in patients with intrauterine adhesions,reduce the incidence of postoperative complications,so it is worthy of application and promotion.
