Case Reports"Crime scene investigation" at an anesthetic cocktail party with atrioventricular dissociation.
A healthy 21-year-old female patient received midazolam, propofol, fentanyl, rocuronium, nitrous oxide in oxygen, ranitidine, diclofenac, neostigmine and glycopyrrolate during the anesthetic process for elective knee arthroscopy and developed a complete AV dissociation with a P-wave frequency of 40 and a "small" QRS-complex frequency of 55 beats/min. Based on this typical case of poly-pragmatic anesthetic drug administration causing a complete atrioventricular dissociation in a young healthy patient we will discuss the possible pharmacodynamic mechanisms of all used drugs with regard to the cardiac conduction system.

ReviewPreoperative anxiety in children risk factors and non-pharmacological management.
It is important for anesthesiologists to appreciate the impact of preoperative anxiety in children. Not only does it cause suffering in many children prior to their surgical experience, it has a negative impact on their postoperative recovery and possibly long afterwards. Because of these concerns, continued research is warranted to seek ways of minimizing their fears in the perioperative setting. ⋯ This review will also explore issues surrounding parental presence during a child's anesthesia induction and how understanding child development can enhance their cooperativeness during the preoperative period, especially during anesthesia induction. Non-pharmacological interventions as a means of decreasing pediatric anxiety will be explored. Finally recent trends and new directions will be touched upon.

Randomized Controlled Trial Comparative StudyEffect of propofol titration v/s bolus during induction of anesthesia on hemodynamics and bispectral index.
Propofol when given as 2 mg/kg IV bolus for induction of anesthesia is known to cause hypotension requiring vasopressors. The objective of our study was to compare Propofol 2 mg/kg single IV bolus (Precalculated group, PG) with the titration of Propofol (Titration group, TG) to clinical parameters as 10 mg IV increments every 3 seconds on hemodynamic Parameters and Bispectral Index (BIS), during induction. The effect of titration on dose requirement for induction was also evaluated. ⋯ Titration of Propofol reduces hemodynamic changes, dose requirement and is able to achieve same level of BIS as in bolus.

Review Comparative StudyContemporary anesthesia management for liver transplantation: a comparison of American and European methods.
This review article compares the organization of liver transplantation programs, anesthesia management and postoperative care in the United States and Europe. Liver transplantation is a definitive treatment for end-stage liver disease. The procedure is extremely complex and requires excellent surgical technique and experienced anesthesiologists who are able to provide precise management. ⋯ Thromboelastography, which is routinely used in the United States for overseeing coagulation, is now increasingly being used in Europe, and seems to be highly effective in providing precise information about coagulation. The overall ICU stay in Europe is longer than in the United States, and services such as maintenance of critical care, immunosuppression and nutrition are not separated in Europe. Despite these differences in liver transplantation programs, overall one-year patient survival rate is similar in the United States and in Europe, exceeding 85% in both.

ReviewMucopolysaccharidoses: anesthetic considerations and clinical manifestations.
Mucopolysaccharidosis (MPS) is a group of genetic disorders that presents challenges during anesthetic care and in particular difficulty with airway management. Patients should be managed by experienced anesthesiologists at centers that are familiar with these types of conditions. Rarely encountered disease states have been identified as important topics in the continuing education of clinical anesthesiologists. This review will define MPS, describe the pathophysiology of MPS, describe how patients with this rare lysosomal storage disorders have dysfunction of tissues, cite the incidence of MPS, list the clinical manifestations and specific problems associated with the administration of anesthesia to patients with MPS, present treatment options for patients with MPS, define appropriate preoperative evaluation and perioperative management of these patients, including, to anticipate potential postoperative airway problems.
