ObjectiveTo summarize the methods to prevent pulmonary complications in patients underwent abdominal surgery during perioperative period and provide reference for the prevention of postoperative pulmonary complications.MethodLiteratures on the prevention of pulmonary complications after abdominal surgery were searched and reviewed.ResultsThe prevention of pulmonary complications after abdominal surgery included preoperative measures, intraoperative measures, and postoperative measures. Preoperative measures included preoperative education, patient risk assessment, smoking cessation, and so on. Intraoperative measures included anesthetic measures and surgical measures. Postoperative measures included atomization treatment, elimination of bad feelings, early postoperative activities, and so on. In view of the different basic conditions of patients underwent abdominal surgery, the selection and emphasis of preventive measures were also different.ConclusionThe prevention of postoperative pulmonary complications after general abdominal surgery should not only take preventive measures in perioperative period, but also should carry out individual management according to the patient’s condition and general conditions.
ObjectiveTo determine the predictive value of preoperative systemic immune-inflammatory index (SII) regarding the development of postoperative pulmonary complications (PPCs) after abdominal surgery.MethodsThisretrospective study involved 433 patients undergoing elective abdominal surgery. Logistic regression risk model was used to evaluate the prognostic value of SII. We drew the receiver-operating characteristic (ROC) curve and calculated the area under the ROC curve to compared the predictive ability of SII, platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), and monocyte-to- lymphocyte ratio (MLR).ResultsThe independent risk factors of PPCs were preoperative respiratory diseases, preoperative history of chronic liver disease, maintenance of intravenous or inhalation anesthesia, and intraoperative infusion of more colloid (P<0.05). However, SII, PLR, NLR, and MLR did not predict the occurrence of PPCs, and they also did not predict ≥3 grade of PPCs (AUC<0.60, P>0.05).ConclusionsPreoperative SII is not a prognostic biomarker of PPCs occurrence in patients undergoing elective abdominal surgery. Other biomarkers, such as PLR, NLR, and MLR, also have no predictive value for the PPCs in these patients.
ObjectiveTo systematically review the effect of perioperative supplemental oxygen administration on surgical site infection (SSI) in patients underwent abdominal surgery with general anesthesia. MethodsDatabases including PubMed, EMbase, The Cochrane Library (Issue 2,2015), CBM, VIP, WanFang Data and CNKI were searched to collect randomized controlled trials (RCTs) about perioperative supplemental oxygen administration versus normal FiO2 in patients underwent abdominal surgery with general anesthesia from inception to March, 2015. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, meta-analysis was conducted using RevMan 5.3 software. ResultsA total of 13 RCTs involving 3 532 patients were included. The results of meta-analysis indicated that: the incidence of SSI in the perioperative supplemental oxygen administration group was lower than that in the control group (OR=0.68, 95%CI 0.47 to 0.99, P=0.04). There were no significiant differences between both groups in incidence of atelectasis, incidence of infection requiring reoperation and 30-day mortality after surgery (all P values >0.05). ConclusionPerioperative supplemental oxygen administration could further decrease the risk of SSI in patients underwent abdominal surgery with general anesthesia, and does not increase the risk of other adverse events. Due to the limitations of quality of included studies, more high quality studies are needed to verify the above conclusions.
ObjectiveTo investigate the effect of tension suture on healing quality of incision after abdominal surgery, and to provide a theoretical basis for reducing post-operative wound complications. MethodLiteratures on the tension suture in the application of abdominal incision were searched from January 2005 to January 2015, and then a Meta-analysis was carried out based on the data obtained from CBM, CNKI, and WanFang database. ResultsEight articles involving 2 001 patients with abdominal surgery, including 1 044 cases in tension suture group, and 957 cases in the conventional suture group, were incorporated. The Meta analysis results showed that, the technique of tension suture could reduce the incidence of post-operative wound infection (OR=0.40, 95% CI: 0.28-0.57, P<0.05), fat liquefaction (OR=0.51, 95% CI: 0.37-0.69, P<0.05), incisional hernia (OR=0.11, 95% CI: 0.04-0.34, P<0.05), wound dehiscence (OR=0.13, 95% CI: 0.07-0.25, P<0.05), and second stage surgery (OR=0.16, 95% CI: 0.09-0.30, P<0.05). But, it would also augment the risk of post-operative skin incision necrosis (OR=15.14, 95% CI: 2.79-82.08, P<0.05). On the other hand, the method of tension suture had no effect on the subcutaneous hemorrhage in the incision area (OR=0.58, 95% CI: 0.30-1.13, P>0.05). ConclusionsCompared with conventional suture, tension suture can reduce the hazard of wound infection, fat liquefaction, incisional hernia, wound dehiscence, and reoperation after abdominal surgery. In contrast, it can also increase the risk of post-operative skin incision necrosis.

Objective To evaluate the effects of a preoperative pain education program on patients’ knowledge of postoperative pain management, measures taken for such pain management and the actual postoperative pain. Methods A total of 84 patients undergoing abdominal surgery were non-randomly divided into two groups, 42 in each group. Patients in group A received routine preoperative care and 30 minutes of education about pain management, while patients in group B received routine preoperative care only. All patients completed the Postoperative Pain Management Questionnaire on the second postoperative day. Results Patients in group A achieved higher scores for their knowledge about postoperative pain management than those in group B (Plt;0.05). More patients in group A took non-medical pain relief methods after surgery (Plt;0.05); and patients in group A were able to use the PCA pump more correctly than those in group B (Plt;0.05). No significant differences were observed between the two groups in the frequency of asking for analgesics or their pain score when they requested analgesics (Pgt;0.05). The average score for postoperative pain was lower for group A compared to group B (Plt;0.05). Conclusions A program of preoperative pain education can improve patients’ knowledge of postoperative pain management and encourage them to participate actively in such pain management, so as to further relieve the postoperative pain.
Objective To evaluate the clinical short-term efficacy and safety of application of glucocorticoids (GCs) before major abdominal surgery. Methods The randomized controlled trials (RCTs) on application of GCs before major elective abdominal surgery were systematically and comprehensively searched in Medline (1966–2022), Embase (1947–2022), Web of Science, and PubMed databases, and systematic review and meta-analysis of the included studies were performed to explore the effects of application of GCs before major abdominal surgery on postoperative complication, hospital stay, and serum interleukin-6 level. Results Nineteen moderate quality RCTs with 1 535 patients were finally included in the analysis. Preoperative application of GCs reduced postoperative IL-6 level [MD=–51.00, 95%CI (–62.36, –39.63), P<0.001], reduced postoperative complications [OR=0.53, 95%CI (0.35, 0.81), P=0.003], shorten hospital stay [MD=–0.64, 95%CI (–1.04, –0.24), P=0.002], and reduced the occurrence of infectious complications [OR=0.50, 95%CI (0.36, 0.70), P<0.01]. However, there were no statistically significant difference in incidence of anastomotic leakage [OR=1.15, 95%CI (0.43, 3.04), P=0.780] and bile leakage [OR=1.95, 95%CI (0.76, 5.00), P=0.170]. Conclusion Preoperative application of GCs can reduce the level of IL-6, reduce complications after major abdominal surgery and shorten postoperative hospital stay.
ObjectiveTo systematically evaluate the effect of Dexmedetomidine (Dex) on postoperative cognitive dysfunction (POCD) of Chinese patients undergoing abdominal surgeries. MethodsWe searched databases including PubMed, Web of Science, CNKI, CBM, VIP and WanFang Data from inception to April 2015, to collect randomized controlled trials (RCTs) about evaluating the effect of Dex on POCD of Chinese patients undergoing abdominal surgeries. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Then, RevMan 5.3 software was used for meta-analysis. ResultsA total of 8 RCTs were included. The results of meta-analysis showed that:compared with the control group, the MMSE scores of the Dex group were higher after surgeries in the first day (MD=1.46, 95%CI 0.98 to 1.95, P<0.000 01), the second day (MD=2.46, 95%CI 2.11 to 2.81, P<0.000 01), the third day (MD=1.81, 95%CI 0.37 to 3.25, P=0.01) and the seventh day (WMD=2.03, 95%CI 1.64 to 2.43, P<0.000 01). ConclusionCurrent evidence shows that the usage of Dex during abdominal surgeries can reduce the incidence of POCD in Chinese patients. Due to the limited quantity and quality of included studies, more high quality studies are needed to verify the above conclusion.
ObjectiveTo research the effect of different surgical sutures on abdominal surgical incision healing quality, and provide a novel theory basis for promoting the healing of incision of abdominal wall. MethodsTotally 341 patients who underwent laparotomy were collected from general surgery of Affiliated Hospital of North Sichuan Medical College, and they were randomly divided into three groups: the including polydioxanoneⅡ(PDSⅡ) suture group, abdominal wall incision except the skin was successively sutured with PDSⅡsuture; the Vicryl group, abdominal wall incision except the skin was successively suture with antibacterial Vicryl; and the common silk thread group, abdominal wall incision was performed layering intermittent silk suture. ResultsIn terms of suture time, the PDSⅡsuture group [(11.23±1.62) min〕was significantly lower than the Vicryl group [(14.04±1.20) min〕, P < 0.05, and also both were significantly lower than the ordinary silk thread group [(21.95±1.95) min〕, P < 0.05. In respect of rejection reaction, incision infection and incision split, the PDSⅡsuture group and the Vicryl group were significantly lower than the ordinary silk thread group (P < 0.05), but compared the PDSⅡsuture group with the Vicryl group, the differences were not statistically significant (P > 0.05). Regarding post operation hospitalization duration, fat liquefaction and effusion, compared the differences between the three groups were not statistically significant (P > 0.05). ConclusionFull fascia is successively suture with PDSⅡsutures and antibacterial Vicryl suture that can significantly shorten the suture time, reduce the incidence of rejection incision, wound infection and wound dehiscence and promote the postoperative recovery of the patients.
