Objective To observe the effect of parenteral nutrition (PN) on the protein storage and immunofunction in patients with liver cirrhosis. Methods PN regimes consisted of nonprotein calories (NPC) 20-25 kcal/(kg·d) and nitrogen 0.15-0.20 g/(kg·d), the energy ratio of the glucose and fat emulsion was 2∶1. The PN solution was infused by total nutrition admixture (TNA), 12-16 hours per day for 7 days in 21 liver cirrhosis patients. Perior to the surgery and at 1st, 4th, 7th postoperative day, serum pre-Alb, transferrin (TSF), immunofunction (IgG, IgA, IgM, IgE, CH50, C3, C4, CD3, CD4, CD8, NKC), and nitrogen balance were tested. Results Serum pre-Alb, TSF, nitrogen balance and IgG, IgE, CH50, CD3, CD4, NKC were significantly decreased (Ｐ＜0.05), but the foregoing indices were higher than those of postoperative 1, 4d as compared with postoperative 7d. Conclusion These results bly indicated that postoperative nutritional support is safe and useful, and improve the patient’s nutritional status and immunofunction.
ObjectiveTo systematically review the efficacy of opioid-sparing analgesic techniques in terms of analgesic potential, incidence of complications and quality of recovery in liver surgery. MethodsThe PubMed, Embase and Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to August 2023. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. Meta-analysis was then performed by using RevMan 5.3 software. ResultsA total of 20 RCTs involving 1 347 patients were included. The results of meta-analysis showed that opioid-sparing techniques could significantly reduce pain scores at rest and during movement from 2h to 48h postoperatively, opioid consumption within 24h (MD=−11.17, 95%CI −14.62 to −7.71, P<0.01) and 48h (MD=−7.19, 95%CI −10.06 to −4.33, P<0.01), postoperative nausea and vomiting (PONV) (OR=0.68, 95%CI 0.50 to 0.91, P=0.01) and wound infection (OR=0.42, 95%CI 0.18 to 0.98, P=0.04), as well as reduced time to bowel recovery (MD=−12.92, 95%CI −21.24 to −4.61, P<0.01) and decreased length of hospital stay (LOS) (MD=−0.90, 95%CI −1.32 to −0.49, P<0.01). No significant difference was observed between the two groups in the incidence of excessive sedation, pruritus, hypotension, headache and respiratory depression. Time to out-of-bed activity and patient satisfaction were also similar between groups. ConclusionOpioid-sparing techniques are effective in relieving postoperative pain and reducing opioid use, with additional potential in reducing postoperative nausea or vomiting, wound infection, time to bowel recovery and length of hospital stay.
ObjectiveTo investigate the correlation between perioperative blood transfusion and hepatic postoperative infection. MethodsOne hundred and thirty patients undergoing hepatic operation were analyzed retrospectively on the relation of perioperative blood transfusion with postoperative infective morbidity and mortality in the period 1989-1999. The patients were divided into blood transfused group and nontransfused group. The major or minor hepatectomy was performed in 53 patients with hepatic malignancy and benign diseases. ResultsIn the blood transfused group, the infective morbidity and perioperative mortality rate was 38.5% and 16.7% respectively, significantly higher than those in nontransfused group (11.5% and 3.8% respectively), P＜0.05. The total lymphocyte count was lower in transfused group than that in nontransfused group. The postoperative antibiotics used time and length of hospital stay were (9.7±4.2) days and (18.7±13.1) days respectively in transfused group than those in nontransfused group (5.3±2.3) days and (12.7±5.2) days respectively. ConclusionThe results suggest that hepatic postoperative infective morbidity and mortality are related with perioperative blood transfusion. Any strategy to reduce blood loss in liver surgery and decrease blood transfusion would be helpful to lower postoperative infective morbidity.
