ABSTRACT
We report the case of a 58-year-old woman who developed rejection and acute lung injury 10 days after an orthotopic liver transplantation while receiving total parenteral nutrition. Examination of bronchoalveolar lavage fluid revealed large lipid droplets in the alveolar macrophages. Intensification of the immunosuppressive therapy attenuated the liver allograft rejection followed by resolution of lung injury.

Our study aimed at evaluating the effect of blood transfusion - allogeneic or autologous - on plasma levels of fibronectin during liver resections. Thirty-five patients scheduled for liver resection were randomly allocated to receive autologous (group autologous blood transfusion (ABT), n= 19) or allogeneic (homologous) (homologous blood transfusion (HBT), n= 16) packed red blood cell to maintain serum haemoglobin concentration above 9 g. Serum levels of fibronectin were measured before induction of anaesthesia, at the end of operation and at first, third and sixth postoperative day. Perioperative morbidity and survival rate were also recorded. Serum fibronectin levels were significantly higher (P < 0.05) in the autologous group than in the allogeneic, at the first (134 +/- 49 microg mL(-1) vs. 89 +/- 31 microg mL(-1)) and third (178 +/- 51 microg mL(-1) vs. 96 +/- 41 microg mL(-1)) postoperative day. No differences in survival and complication rate between the two groups were observed. Concentrations of serum fibronectin seem to be adversely affected by allogeneic blood transfusion during liver resection surgery, although this does not seem to affect patients' morbidity and mortality.

BACKGROUND AND OBJECTIVE: We examined the efficacy of intraoperative propofol administration to prevent pruritus induced by epidural morphine. METHODS: Seventy patients ASA I-II undergoing combined epidural and general anaesthesia for hysterectomy were randomly assigned to two groups, Group P where anaesthesia was induced with propofol and fentanyl and maintained with propofol-nitrous oxide and Group S in which anaesthesia was induced with thiopental and fentanyl and maintained with sevoflurane-nitrous oxide. All patients received a ropivacaine epidural bolus with 3 mg morphine 1 h before the end of surgery. The incidence and severity of pruritus were evaluated every 4 h for the first 12 h postoperatively by blinded observers. RESULTS: The total incidence of pruritus was significantly higher (P = 0.024) in Group S (65.6%) compared to Group P (29%) between 4 and 8 h postoperatively. There were also significantly more patients (P = 0.03) reporting severe pruritus in Group S (22%) compared to Group P (0). CONCLUSION: Propofol-based general anaesthesia compared to thiopental-sevoflurane-based anaesthesia reduces the incidence and severity of pruritus induced by a single injection of 3 mg epidural morphine with ropivacaine.

OBJECTIVE: We investigated the dose-related effect of dopexamine and dopamine on free radical production and lipid peroxidation estimated by MDA measurements in an ischaemia-reperfusion model of supraceliac aortic repair. DESIGN: Prospective, randomized, blinded experimental study. MATERIALS: Twenty-five healthy pigs. METHODS: All experiments were performed under general endotracheal anaesthesia. Supraceliac aortic cross clamping was performed in all pigs. The pigs were randomly assigned into five groups (n=5 in each group) and received a continuous intravenous infusion of normal saline (CTL), dopamine 2 microg kg(-1)min(-1) (dopa 2), dopamine 8 microg kg(-1)min(-1) (dopa 8), dopexamine 2 microg kg(-1)min(-1) (dopex 2), dopexamine 8 microg kg(-1)min(-1) (dopex 8). Cardiac output, mean arterial pressure, arterial blood gas analysis and blood sampling for plasma MDA measurements (to reveal lipid peroxidation) were recorded after induction of anaesthesia (baseline), 60 and 120 min after cross-clamping of aorta (ischaemia phase), and 60 and 120 min after restoration of flow (reperfusion phase). RESULTS: Dopexamine and dopamine at 8 microgkg(-1)min(-1) reduced MDA at 60 and 120 min after reperfusion. CONCLUSION: Dopexamine seems superior to dopamine in reducing oxygen free radicals and subsequent lipid peroxidation during reperfusion after supraceliac aortic cross clamping in pigs.
