ABSTRACT
Objective:To investigate the effect of intraoperative body temperature on prognosis of elderly patients with strangulated small bowel obstruction.Methods:The clinical data of 113 elderly patients with strangulated small intestinal obstruction and perform partial resection and anastomosis admitted to the Affiliated Hospital of Southwest Medical University from December 2017 to June 2022 were retrospectively analyzed. The ROC curve was used to analyze the relationship between the intraoperative body temperature(T) and the prognosis of patients, so as to obtain the optimal cutoff point (Ta). According to the relationship between T and Ta, all patients were divided into hypothermia group (33 cases) (T<Ta) and hyperthermia group (80 cases)(T ≥ Ta), and the differences in prognosis between the 2 groups were compared and Logistic regression was applied to analyze the influence of prognostic factors.Results:The optimal cutoff value (Ta ) of ROC curve was 36.45℃. The incidence of postoperative complications in hypothermia group was 60.6% (20/33), higher than 6.3%(5/80) in hyperthermia group ( χ2=40.06, P<0.01). Multivariate analysis by Logistic regression revealed that enteric perforation and lower intraoperative body temperature were risk factors for surgical prognosis ( OR=9.874, 95% CI 1.260-77.400; OR=69 865.637, 95% CI 90.799-53 758 097.700, both P<0.05). Conclusions:Intraoperative body temperature was a factor affecting surgical prognosis in elderly patients with strangulated small bowel obstruction. The temperature lower than 36.45 ℃ during the operation indicated that the patients were more prone to complications and had worse prognosis. Intensive temperature management was required intraoperatively in elderly patients, and nursing interventions such as warming and heating blankets were necessary.
ABSTRACT
Objective To make a systematical review of the safety and efifcacy of Etomidate plus Fentanyl-class drugs and Propofol plus Fentanyl-class drugs in older patients undergoing gastroscopy. Methods We searched the Cochrane library, PubMed, Embase, China Biology Medicine (CBM), CNKI, VIP, Wanfang Database for all randomized controlled trials (RCTs) about the efifcacy of Etomidate plus Fentanyl-class drugs(Fentanyl, Sufentanil, remifentanil) in older patients undergoing gastroscopy. The quality of the studies was evaluated by the method recommended by the Jadad scale. Meta-analysis was conducted using the Cochrane Collaboration’s RevMan 5.3 software. Results 11 RCTs involving 1 535 patients were analyzed. Meta-analysis showed that patients in the Etomidate group had a lower heart rate [Weighted Mean Difference (WMD)=2.25, 95%CI(0.93, 3.56), P=0.001] and mean arterial pressure [WMD=9.09, 95%CI (7.60, 10.57), P=0.000] lfuctuation than whose of the Propofol group.The hypoxemia occurrence [O
ABSTRACT
BACKGROUND:Psychological factors could influence the degree of pain after total knee arthroplasty. However, the effects of perioperative psychological intervention on postoperative pain and joint function are rarely reported. OBJECTIVE:To study the efficacy and safety of alprazolam for patients with anxiety and depression before total knee arthroplasty. METHODS:Sixty-one patients with anxiety and depression before unilateral total knee arthroplasty were recruited. The patients were given the treatment of alprazolam (experimental group) or placebo (control group) at 2 weeks preoperatively. Baseline data were collected, preoperative anxiety and depression were assessed with Hamilton Anxiety Scale and Beck Depression Inventory, perioperative pain at rest and in activity at each time point was evaluated, postoperative NSAIDs drugs and intravenous self-control analgesia pump usage were recorded, the peripheral neurotransmitters were detected by ELISA, short-and mediate-term joint fuction was evaluated through Western Ontario and McMaster Universities Osteoarthritis Index and Knee Society Score after joint replacement, patient satisfaction and in-hospital relevant indexes and adverse reactions were detected. RESULTS AND CONCLUSION:(1) After the application of alprazolam, anxiety and depression were improved notablely, and the levels of 5-hydroxytryptamine andγ-aminobutyric acid in peripheral blood were increased at 2 weeks. (2) The visual analogue scale scores at rest in the experiemntal group were significnatly lower than those in the control group at 12 hours, 1, 2, 3, 5 and 7 days postoperatively (P<0.05);the visual analogue scale scores in activity in the experiemntal group were significnatly lower than those in the control group at 12 hours, 1, 2, 3, and 5 days postoperatively (P<0.05). (3) Analgesia pump and analgesic drug usage in the experiemntal group were significantly less than those in the control group, and the analgesic drug dosage and preoperative anxiety depression were correlated. (4) There were no significant differences in the Western Ontario and McMaster Universities Osteoarthritis Index and Knee Society Score between two groups. (5) The patient satisfaction, sleep index and hospitation time in the experimental group were superior to those in the control group. No obvious adverse reactions occurred during medication. (6) Our results suggest that for patients diagnosised with anxiety and depression before total knee replacement, the preoperative application of alprazolam can alleviate anxiety and depression, improve perioperative pain at rest and in activity, reduce postoperative analgesia drug useage, and increase patient satisfaction.
ABSTRACT
Objective To evaluate the efficiency and safety of non- nasogastric tube on fast-track surgery patients with colorectal cancer. Methods We searched PubMed, CBM, Cochrane Library, CNKI, Wanfang and Vip data. Controlled trials that met the criteria were selected. All reports were collected and analyzed by RevMan5.3. Results 8 reports were enrolled. The non-nasogastric tube group had a shorter anus exhausting time and lower morbidity of pulmonary and throat complications , and it also had a shorter postoperative length of hospital stays. Significant differences were found between the non-nasogastric tube group and the control group (P 0.05). Conclusion Current evidence shows that non-nasgastric tubes are recommended for the patients with colorectal cancer surgery.

ABSTRACT
Objective: To compare supercritical CO 2 fluid extraction(SFE CO 2) with steam distillation(SD) in the chemical constituents and content of essential oil from Forsythia Suspensa. Method: GC MS combination was adopted. Results: Both the two methods shared the same main components as ? pinene, ? pinene and sabinene. Benzene methanol,4 [1 methylethyl] and Benzene methanol,2 [4 methylethyl] were extracted exclusively by SFE CO 2, Among two methods there is a good deal of similarity all the other components extracted. Furthermore, sabinene、transpinocarveol and shorten were the first obtained from the plant. Conclusion: The SFE CO 2 was superior to SD in raising yield and reducing extractive time. It is a good method in extracting the essential oils from Forsythia Suspensa.
