Review Case Reports
Delayed pneumomediastinum and pneumothorax complicating laparoscopic extraperitoneal inguinal hernia repair.
A 53-year-old healthy man underwent elective laparoscopic, extraperitoneal, right-sided herniorrhaphy. Postoperatively, he complained of chest pain on inspiration. Chest x-ray and computed tomographic scan revealed a pneumomediastinum and a right-sided pneumothorax. Previous case reports and possible etiologies are reviewed.

Review Comparative Study
Comparative efficacy and costs of various topical anesthetics for repair of dermal lacerations: a systematic review of randomized, controlled trials.
To compare the efficacy of infiltrated local anesthesia with topical anesthesia for repair of dermal laceration, to analyze the efficacy of single or multicomponent topical anesthetics, and to identify topical formulations that are potentially less costly and equally efficacious as cocaine-containing topical anesthetics. ⋯ Topical anesthetics are an efficacious, noninvasive means of providing analgesia before suturing of dermal lacerations. The use of cocaine-containing topical anesthetics can no longer be justified in light of its high cost and potential adverse effects. We have summarized the evidence, mostly favorable, supporting the use of various non-cocaine-containing topical anesthetics.

The prevalence of obesity has increased 15% up to 20% and represents an important challenge for the anesthesiologist in drug-dosing management. The aim of this work is to provide an overview on physiological changes and pharmacokinetic implications of obesity for the anesthesiologist. Obesity increases both fat and lean masses; however, the percentage of fat tissue increases more than does the lean mass, affecting the apparent volume of distribution of anesthetic drugs according to their lipid solubility. ⋯ Inhalation anesthetics with very low lipid solubility, such as sevoflurane and desflurane, allow for quick modification of the anesthetic plan during surgery and rapid emergence at the end of surgery, hence representing very flexible anesthetic drugs for use in this patient population. Drug dosing is generally based on the volume of distribution for the loading dose and on the clearance for maintenance. In the obese patient, the volume of distribution is increased if the drug is distributed both in lean and fat tissues whereas the anesthetic drug clearance is usually normal or increased.

Review Case Reports
Care of the injured Jehovah's Witness patient: case report and review of the literature.
Care for the Jehovah's Witness patient can be a challenge and often a dilemma to clinicians because of the patient's religious beliefs and teachings against receiving blood and blood products, especially in emergency or trauma settings. We present a case of a severely injured elderly Jehovah's Witness patient who survived. We also review the literature and offer an organized approach to care for such patients.

Informed consent is a cornerstone and routine component of the ethical practice of modern medicine. Its full theoretical application to specific clinical situations, however, presents a number of ethical dilemmas for health care providers. Obstetric anesthesia, in particular, presents many unique challenges to the process of informed consent. ⋯ The application of principlism to actual clinical situations, the limitations of principlism in the peculiarities of the patient-physician encounter, as well as possible alternative models of ethical discourse is discussed. The process of informed consent can be broken down into seven elements: Threshold elements or preconditions, which include 1) decision-making capacity or competency of the patient, 2) freedom or voluntariness in decision-making, including absence of over-riding legal or state interests; informational elements, including 3) adequate disclosure of material information, 4) recommendation, and 5) an understanding of the above; consent elements, which include 6) decision by the patient in favor of a plan and 7) authorization of that plan. Each of these elements is discussed in turn, and their implications, especially for the anesthesiologist and the obstetric patient, are addressed.
