In order to observe electrolyte changes before and after scheduled abdominal surgery and effect of prompt potassium supplement on the recovery of gastrointestinal function, electrolytes in 69 patients were tested before and after surgery, and the recovery of the gastrointestinal function was observed.The results showed that after surgery the levels of K＋, Na＋ and Cl＋ were decreased dramatically (Ｐ＜0.05) but still within the normal range, with no distinctive change in Ca２＋ and Mg２＋. No correlation between the amount of blood transfusion and potassium was detected. Prompt potassium supplement contributed to the quick recovery of gastrointestinal function.This suggests that with normal renal function, blood transfusion during the operation will not cause hyperkalemia, potassium supplement might begin on the first day when the patient begins to urinale.
Objective To research the effects of recombinant growth hormone (rhGH) with total parenteral nutrition (TPN) on nitrogen balance and nutritional state of the patients following major abdominal surgery. Methods We randomly selected 45 patients receiving TPN after major abdominal surgery and distributed them to study group (rhGH+TPN, n＝30) and control group (TPN only, n＝15). For 7 days after operation, every one was given rhGH 4u or replaced by hypodermic injection of normal saline (control group). Results TPN+rhGH promoted the rehabilitant of nitrogen balance, heightened the level of plasma albumin and transferrin and increased the weight and creatinin/height index (CHI), but the thickness of triceps skin fold (TSF) had no significant change in patients following major abdominal surgery. Conclusion The rhGH can improve the effects of TPN.
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 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 explore the effect of standardized multimodal analgesia (SMA) on opioid consumption after major upper abdominal surgery under enhanced recovery after surgery pathway. MethodsPatients who underwent major upper abdominal surgery in the West China Hospital of Sichuan University between August and November 2020 were included prospectively. The patients were divided into two groups: SMA group (n=175) and control group (n=632). The SMA was defined as preoperative and postoperative use of non-steroidal anti-inflammatory drugs, combined with regional anesthesia, local anesthetic wound infiltration or intrathecal opioid. The postoperative opioid consumption in oral morphine equivalents, the pain scores on movement and at rest, the postoperative rehabilitation were recorded and compared between the two groups. ResultsPatients in the SMA group had a lower opioid consumption during the first 72 h compared to patients in the control group (median: 51 mg vs. 85 mg, P<0.001). The pain scores on movement and at rest at 24, 48, 72 h after surgery in the SMA group were lower than those in the control group (P<0.05). Time to first flatus, time to first ambulation, postoperative hospital stay in the SMA group were significantly shorter than those in the control group (P<0.05), and the quality of life scores at 5 d after surgery increased significantly (P<0.05). The satisfaction with analgesia and the incidence of adverse effects on day 5 after surgery had no statistical significances between the two groups (P>0.05). After controlling for confounding factors, multiple linear regression analysis showed that SMA was associated with less opioid consumption on hour 72 after surgery (P<0.001). ConclusionSMA can reduce postoperative opioid consumption in patients undergoing major upper abdominal surgery.
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.
