Low birth weight (<1500 g) and associated cardiac pathology were found to be independent predictors of mortality in infants undergoing surgery for TEF/EA repair. The presence of a ductal-dependent cardiac lesion further increased the risk of morbidity and mortality, in addition to necessitating special anesthesia considerations.

The influence of steatosis on the outcome of orthotopic liver transplantation (OLT) was evaluated in 860 liver transplantations carried out in 784 patients from October 1990 to August 2001. Donor variables considered were: age, hepatic enzymes, bilirubin, total and warm ischemia times, macrovesicular and microvesicular steatosis. Recipient variables considered were: age, UNOS status, Child-Pugh score and indication for OLT. Patient and graft survival were the main outcome indicators. Macrovesicular steatosis affecting 15% or more of the hepatocytes was the only variable independently associated with shorter patient and graft survival (P = 0.0012 and 0.0028).A significantly worse prognosis was to be expected if >15% macrovesicular steatosis was associated with a total ischemia time >10 h (P= 0.048), or donor age >65 years (P=O.O16) or with HCV-positive recipients (P = 0.0014). From our study we can conclude that macrovesicular steatosis involving 15% or more of the hepatocytes identifies marginal livers. The risk of graft non-function or patient loss after OLT rises if macrovesicular steatosis H5y0 is associated with long ischemia time, high donor age, or HCV positivity in recipients.

In this prospective, randomized study, we investigated the adequacy of a single intrathecal injection of fentanyl for intraoperative analgesia, compared the effects of IT and IV fentanyl on stress response, and assessed for an additive effect of IT and IV fentanyl administration in pediatric cardiac anesthesia. The results with these three different anesthetic regimens were similar regarding anesthesia depth and level of stress response. However, the combination of IT and IV routes may provide better hemodynamic stability and a less pronounced stress response, as reflected by 24-h urinary cortisol excretion.

BackgroundIndications for flow diversion stent (FDS) treatment are expanding. However, there is still a lack of evidence for the long-term outcome in distally located aneurysms in the M2 segment of the middle cerebral artery (MCA) and beyond.MethodsConsecutive subjects (from June 2013 to August 2020) with MCA aneurysms in the M2 segment or beyond treated with FDS were reviewed retrospectively. The primary endpoints for clinical safety were the absence of mortality, stroke event, re-rupture of the aneurysm, and worsening of clinical symptoms. The primary endpoint for treatment efficacy was complete/near-complete occlusion at follow-up after 12 months.Results23 patients were identified: 7 aneurysms were located in the M2 segment of the MCA, 4 in the M2-M3 bifurcation, 2 in M3, 3 in M3-4 branching, and 2 in M4; 5 aneurysms were located in M2 with extension into the M1-M2 bifurcation. 13 aneurysms were of fusiform morphology, 8 sacculofusiform, and 2 saccular. 16 aneurysms were of highly suspected dissecting etiology. The median diameter of the parent vessel was 2.1 mm proximally and 2 mm distally. The median time of the follow-up was 30 months (range 16 months to 6 years). Complete/near complete occlusion was observed in 14/20 patients (70%) and one stable remodeling (5%) was seen at 12 months. 22 patients (95.6%) had an excellent clinical outcome (mRS 0–1) at 6 months. Technical challenges associated with the deployment of FDS occurred in 8.7% of cases. Severe complications, intraparenchymal hemorrhage and re-rupture of the aneurysm occurred in 2 patients (8.7%).ConclusionFlow diversion of distally located aneurysms is technically feasible with low morbidity and mortality.

SummaryObjectives: Propofol causes considerable pain upon injection, although different methods and propofol formulations have been used to decrease this pain. We aimed to investigate the effect of i.v. esmolol pretreatment on propofol injection pain.Methods: Ninety ASA I-II patients undergoing elective surgery under general anesthesia were randomly assigned into three groups of thirty each. A 20 G cannula was inserted into the dorsum of the nondependent hand. After venous occlusion for one minute, groups E, L and S were pretreated with 5 mg/ml (total 2 ml) esmolol, 40 mg lidocaine and 2 ml saline i.v. respectively. After release of venous occlusion, one fourth of the total propofol dose was administered at a rate of 0.5 ml/sec. During the injection of both pretreatment solution and propofol, patient pain was assessed by using 4 point scale. Heart rate and noninvasive arterial blood pressure values were recorded before induction, just after entubation and five minutes after entubation. Results:Demographic values were similar among groups. Incidence of pain on injection of propofol in the control, esmolol and lidocaine groups was 90%, 33.3%, 50% respectively (p<0.05). Heart rate, systolic arterial pressure, and diastolic arterial pressure values were not different between the groups.Conclusion: Pretreatment with low dose esmolol i.v. seems to be effective in attenuating pain during propofol injection.

Background. This study was conducted to compare and evaluate the effect of adding lornoxicam or nitroglycerine as adjuncts to lidocaine in intravenous regional anesthesia (IVRA). Methods. 60 patients were randomly separated into three groups, lidocaine group (group L), lidocaine + lornoxicam group (group LL), and lidocaine + lornoxicam + transdermal nitroglycerine group (group LL-N). Hemodynamic parameters, sensory and motor blocks onset, and recovery times were recorded. Analgesic consumption for tourniquet pain and postoperative period were recorded. Results. Sensory block onset times and motor block onset times were shorter in the LL-N and LL groups compared with L group. Sensory block recovery time and motor block recovery time were prolonged in the LL and LL-N groups compared with group L. The amount of fentanyl required for tourniquet pain was less in group LL and group LL-N when compared with group L. VAS scores of tourniquet pain were higher in group L compared with the other study groups. Postoperative VAS scores were higher for the first 4 hours in group L compared with the other study groups. Conclusion. The adjuvant drugs (lornoxicam or TNG) when added to lidocaine in IVRA were effective in improving the overall quality of anesthesia, reducing tourniquet pain, increasing tourniquet tolerance, and improving the postoperative analgesia.
