BACKGROUND: Pharmacologic pre- and postconditioning with sevoflurane compared with total IV anesthesia in patients undergoing liver surgery reduced complication rates as shown in 2 recent randomized controlled trials. However, the potential health economic consequences of these different anesthesia regimens have not yet been assessed. METHODS: An expostcost analysis of these 2 trials in 129 patients treated between 2006 and 2010 was performed. We analyzed direct medical costs for in-hospital stay and compared pharmacologic pre- and postconditioning with sevoflurane (intervention) with total IV anesthesia (control) from the perspective of a Swiss university hospital...

BACKGROUND: Accurate measuring of the hepatic hemodynamic parameters in humans is inconvenient. Swine has been a favorite surgical model for the study of liver conditions due to many similarities with human livers. However, pigs cannot tolerate pedicle clamping and to reduce bleeding during resection a simplified technique is required. The aim of this study is to present a simplified technique for different percentages of hepatic resection in a porcine model. METHODS: Twenty-two consecutive large white pigs were operated with 75% and 90% liver resection...

INTRODUCTION: Natural orifice transluminal endoscopic surgery (NOTES) is a challenging minimally invasive procedure. Although laparoscopic techniques for liver resection are gaining acceptance worldwide, few studies have investigated NOTES liver resection. We used a porcine model to assess the feasibility and safety of transvaginal NOTES liver resection (TV NOTES LR). MATERIALS AND METHODS: Nine female pigs underwent TV NOTES LR. A nonsurvival acute porcine model with general anesthesia was used in all cases...

Hypertension is a common occurrence during general anesthesia. Apart from pathological causes of hypertension, it is rarely extreme enough to be classified as a hypertensive crisis (systolic blood pressure >180 mm Hg or diastolic blood pressure >120 mm Hg). There is literature concerning the unintentional electrocauterization of the adrenal gland leading to hypertensive crisis, but to date, no reports have been made of adrenal stimulation from the use of an Aquamantys for hemostasis. Here, we report such a case when a hypertensive crisis (systolic blood pressure >300 mm Hg) occurred while using an Aquamantys during a liver transplant after unintentional stimulation of the adrenal glands...

OBJECTIVE: Because of concern over medical ionizing radiation exposure of children, contrast-enhanced ultrasound (CEUS) has generated interest as an inexpensive, ionizing radiation-free alternative to CT and MRI. CEUS has received approval for pediatric hepatic use but remains off-label for a range of other applications. The purposes of this study were to retrospectively analyze adverse incidents encountered in pediatric CEUS and to assess the financial benefits of reducing the number of CT and MRI examinations performed...

Anesthesia for patients with moderate aortic stenosis accompanied by atrial fibrillation during high-risk surgery such as liver transplantation remains a challenge in maintaining control of heart rate and maintenance of cardiac output. The action of terlipressin on vasopressin receptors (mainly V1 receptors) leads to splanchnic vasoconstriction and is the key mechanism responsible for increasing systemic vascular resistance and reducing heart rate. We report successful anesthetic management using low-dose terlipressin infusion in an elderly patient who had moderate aortic stenosis with atrial fibrillation during urgent deceased-donor liver transplantation...

BACKGROUND: Morbidity and mortality rates in orthotopic liver transplantation have decreased in the past few years. Risk factors related to severe postoperative complications, such as primary graft dysfunction, still need to be analyzed. We evaluated the influence of the hypnotic agent used during anesthesia on primary graft dysfunction. METHODS: We performed a retrospective analysis of 419 consecutive patients who received a liver transplant between 2005 and 2013 in a single center...

Temporary portocaval shunt (TPCS) prolongs the duration of the anhepatic phase, during which anesthetic sensitivity is highest among the 3 phases of living donor liver transplantation (LDLT). Cognitive dysfunction has been associated with increased anesthetic sensitivity and poor hepatic function. Therefore, we assessed anesthetic sensitivity to desflurane and perioperative cognitive function in patients undergoing LDLT, in whom the duration of the anhepatic phase was extended by TPCS to test the hypothesis that the prolonged anhepatic phase increases anesthetic sensitivity and causes postoperative cognitive decline...

Likely, maintained organ and notably cerebral perfusion, secures rapid recovery following anesthesia. To secure cerebral blood flow (CBF) at least mean arterial pressure (MAP) and the arterial carbon dioxide tension (PaCO2) need to be considered. CBF is "autoregulated", i.e. stays more or less stable within a MAP of 50-150 mmHg, but the lower limit appears to depend on the central blood volume and/or cardiac output, illustrated by a decrease in CBF at a MAP of 80 mmHg with a compromised central blood volume, while CBF remains constant with a MAP < 40 mmHg, if the central blood volume is maintained...

The trans jugular intrahepatic Porto systemic shunt (TIPS) is no longer viewed as a salvage therapy or a bridge to liver transplantation and is currently indicated for a number of conditions related to portal hypertension with positive results in survival. Moreover, the availability of self-expandable polytetrafluoroethylene (PTFE)-covered endoprostheses has dramatically improved the long-term patency of TIPS. However, since the last updated International guidelines have been published (year 2009) new evidence have come, which have open the field to new indications and solved areas of uncertainty...

Many conventional drugs used today, including isoniazid, dapsone, and acetaminophen, are well recognized culprits of hepatotoxicity. With increasing use of complementary and alternative medical therapies, several herbal medicines, such as Ma-Huang, kava, and chaparral leaf, have been implicated as hepatotoxins. Hepatotoxicity may be the most frequent adverse reaction to these herbal remedies when taken in excessive quantities. A myriad of liver dysfunctions may occur including transient liver enzyme abnormalities due to acute and chronic hepatitis...

BACKGROUND AND AIMS: Pediatric use of liver transient elastography (TE) is attractive for its non-invasiveness, but reference values have not been established. We aimed to determine reference values for TE in children. METHODS: In pediatric patients (1 to 18 years), TE (FibroScan®) with an M probe was used for both liver stiffness measurement (LSM) and measurement of hepatic fat deposition by using a controlled attenuation parameter (CAP). The patients were divided into three relevant age groups: preschoolers (1 to 5 years), elementary school children (6 to 11 years), and adolescents (12 to 18 years)...
