ABSTRACT

Objective:To evaluate the relationship between degrees of biliary obstruction and levels of lipid peroxidation in patients.Methods:A total of 140 patients of both sexes, with biliary obstruction, without biliary puncture and drainage, aged 40-64 yr, with body mass index of 18.5-23.9 kg/m 2, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, were selected.The patients with different degrees of biliary obstruction were divided into 4 groups ( n=35 each) according to Child-Pugh grade total bilirubin (TBIL) concentrations: group A (TBIL<17 μmol/L), group B (17 μmol/L≤TBIL<34 μmol/L), group C (34 μmol/L≤TBIL<51 μmol/L) and group D (TBIL≥51 μmol/L). The serum TBIL, direct bilirubin (DBIL), indirect bilirubin (IBIL), alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bile acid (TBA) and malondialdehyde (MDA) concentrations were measured.The correlation between serum MDA concentration and degree of biliary obstruction was tested by Spearman correlation analysis. Results:Compared with group A and group B, the serum DBIL, IBIL, ALT, AST, TBA and MDA concentrations were significantly increased in group C and group D ( P<0.05), and there was no significant difference in the parameters mentioned above between group A and group B ( P>0.05). Compared with group C, the serum DBIL, IBIL, ALT, AST, TBA and MDA concentrations were significantly increased in group D ( P<0.05). Serum MDA concentration was positively correlated with degree of biliary obstruction ( r=0.54, P<0.05). Conclusion:The degree of biliary obstruction can reflect the level of lipid peroxidation in patients.

ABSTRACT

Objective To compare the quadratus lumborum block and transversus abdominis plane block for postoperative analgesia in elderly patients undergoing abdominal surgery. Methods Seventy?two elderly patients of both sexes, aged 65-72 yr, with body mass index of 18-25 kg∕m2, of American Society of Anesthesiologists physical statusⅡorⅢ, scheduled for elective laparoscopic cholecystectomy, were di?vided into 2 groups(n=36 each)by coin toss: transversus abdominis plane block group(group T)and quadratus lumborum block group(group Q). Anesthesia was induced and maintained routinely. Bilateral subcostal transversus abdominis plane block was performed under ultrasound guidance in group T. Bilateral paravertebral approach to quadratus lumborum block was performed under ultrasound guidance in group Q. The height of sensory block was assessed at 30 min after block. Ramsay sedation scores and Bruggrmann comfort scale scores were recorded at 30 min after block and 1, 6, 12, 24 and 48 h after operation. The requirement for parecoxib and fentanyl as rescue analgesics and complications such as nausea, vomiting, block of lower extremities and local anesthetic intoxication were recorded within 48 h after operation. Re?sults The height of sensory block was kept at T4?L1, and the main blocking area was T6?11in group T. The height of sensory block was kept at T4?L4, and the main blocking area was T6?L1in group Q. Compared with group T, the blocking area was enlarged, the requirement for parecoxib and fentanyl and incidence of nausea and vomiting were significantly decreased(P<0.05), and no significant change was found in Ram?say sedation scores or Bruggrmann comfort scale scores in group Q(P>0.05). Conclusion Quadratus lumborum block provides better efficacy for postoperative analgesia than transversus abdominis plane block in elderly patients undergoing abdominal surgery.
