Objective To study the influence of carbon dioxide (CO2)gas temperature on recovery of patients after laparoscopic gastrointestinal operation.Methods 100 cases with gastrointestinal operation patients were selected and randomly divided into the experimental group and the control group with 50 patients in each.In the experimental group,pneumoperitoneum was established with CO2 gas heated to 37 ℃,and the control group used routine method to establish pneumoperitoneum.The items such as postoperative tracheal extubation time,anal exhaust time and extubation time were observed in two groups of patients.Results The endotracheal tube extubation time,anal exhaust time and extubation time in the experimental group were earlier than those in the control group.Conclusions Using CO2 gas heated to 37 ℃ to establish pneumoperitoneum during laparoscopic gastrointestinal operation can effectively promote the rehabilitation of patients after operation.

Background Prolonged awkward postures during occupational activities can lead to excessive musculoskeletal load on the wrist of workers and symptoms such as wrist pain or discomfort. Objective To survey the prevalence of wrist pain among workers in 10 key industries and analyze its correlation with wrist working postures. Methods By using stratified cluster sampling method, workers from 10 key industries, such as footwear manufacturing industry, shipbuilding manufacturing industry, and automobile manufacturing industry, were selected from seven regions in North China, East China, Central China, South China, Southwest China, Northwest China, and Northeast China. The demographic information, wrist working postures, pain in wrist of the workers were collected through a cross-sectional survey. Pearson χ2 test was used to compare prevalence by selected factors, trend χ2 test for between group comparison, and unconditional logistic regression models for the association of wrist working postures with wrist pain. Results There were 64052 workers enrolled in this survey, and 56286 provided valid questionnaires (the effective rate was 87.8%). According to the survey, the prevalence of wrist pain was 23.3% (13112/56286), and the industries with higher prevalences were footwear manufacturing (27.1%, 1927/7106), automobile manufacturing (24.9%, 5378/21560), and shipbuilding and related equipment manufacturing (24.4%, 850/3488) industries. Finger pinching (OR=2.09, 95%CI: 1.95-2.24), frequent wrist bending (OR=2.03, 95%CI: 1.92-2.15), fixed wrist bending (OR=1.77, 95%CI: 1.69-1.85), wrist on hard edge (OR=1.34, 95%CI: 1.28-1.40), and arms over shoulders (OR=1.11, 95%CI: 1.05-1.17) increased the risk of reporting wrist pain. Conclusion Awkward postures are related to wrist pain among workers in selected 10 key industries. The related factors are wrist on hard edge, frequent wrist bending, finger pinching, fixed wrist bending, and arms over shoulders.
