Laparoscopy is the process of inspecting the abdominal cavity through an endoscope. Carbon dioxide is most universally used to insufflate the abdominal cavity to facilitate the view. However, several pathophysiological changes occur after carbon dioxide pneumoperitoneum and extremes of patient positioning. ⋯ Local anesthesia infiltration has shown to be effective and safe in microlaparoscopy for limited and precise gynecologic procedures. However, intravenous sedation is sometimes required. This article considers the pathophysiological changes during laparoscopy using carbon dioxide for intra-abdominal insufflation, outlines various anesthetic techniques of general and regional anesthesia, and discusses recovery and postoperative complications after laparoscopic abdominal surgery.

Anesthesiologists in every subspecialty encounter, with varying regularity, patients presenting for surgery during the course of pregnancy. With the increasing sophistication of surgical and anesthetic techniques, increasingly complex surgeries are being undertaken. In this review, we address the fundamental physiologic principles central to the care of pregnant patients and fetuses in this difficult clinical situation.

Anesthesiologists are often involved in the early management and resuscitation of patients who have sustained cervical spine injuries (CSIs). The most crucial step in managing a patient with suspected CSI is the prevention of further insult to the cervical spine (C-spine). In this review, important factors related to initial management, diagnosis, airway and anesthetic management of patients with CSI are presented. ⋯ A high level of suspicion and anticipation are the major components of decision making and management in a patient with CSI. Endotracheal intubation using the Bullard laryngoscope may have some advantages over other techniques as it causes less head and C-spine extension than the conventional laryngoscope, and this results in a better view. However, the current opinion is that oral intubation using a Macintosh blade after intravenous induction of anesthesia and muscle relaxation along with inline stabilization is the safest and quickest way to achieve intubation in a patient with suspected CSI. In summation caution, close care and maintenance of spinal immobilization are more important factors in limiting the risk of secondary neurological injury than any particular technique.

When spinal and epidural anesthesia were introduced into clinical practice, their primary use was as an alternative to general anesthesia. Later, largely as a result of the realization that opioids could be safely and effectively used to produce selective spinal analgesia, spinal and epidural (neuraxial) analgesia began to be used specifically for the treatment of perioperative pain. We present a systematic review of the literature on neuraxial anesthesia and analgesia, new meta-analyses that illustrate the powerful effect of improvements in perioperative safety in general on the ability of neuraxial techniques to make a difference, and a consideration of why a literature analysis does not provide clear answers.

Recently, there has been a focus on the teaching of professionalism in postgraduate medical education. Many discussions and studies have been performed to help in teaching professionalism and in the evaluation of the effectiveness of this teaching process. Unfortunately, many anesthesiologists are unaware of the literature and the discussions that have taken place. This review article serves as a primer for those individuals faced with the task of instilling the concepts of professionalism, not only in trainees but also in anesthesiologists practicing today.
