Current opinion in anaesthesiology

To highlight the problems faced in developing countries where healthcare resources are limited, with particular emphasis on pediatric anesthesia. ⋯ The real risk of anesthesia in comparison to other major health risks such as human immunodeficiency virus, malaria, tuberculosis and trauma remains undetermined. The critical shortage of manpower remains a barrier to progress. Despite erratic electrical supplies, inconsistent oxygen delivery, paucity of drugs or equipment and on occasion even lack of running water, many provide life-saving anesthesia. Perioperative morbidity and mortality is, however, understandably high by developed world standards.

New topics in pediatric regional anesthesia are discussed. ⋯ Prolonged analgesia with continuous peripheral nerve blocks in the treatment of pediatric postoperative limb pain, sometimes with patient-controlled regional analgesia, should be preferred instead of continuous epidural analgesia. Levobupivacaine and ropivacaine display the same pharmacokinetic profile as racemic bupivacaine with less cardiac toxicity. Conversely, continuous infusion of these new local anesthetics offers the safest therapeutic index, especially in infants. Many adjuvants have been used, but clonidine offers clear advantages. Ultrasonography guidance blocks will probably become the reference technique for local anesthetics injection and regional anesthesia catheter placement; new training in this field should be available.

Many patients who smoke cigarettes require anesthesia and surgery. Their smoking can have profound consequences for perioperative management. Efforts to help them quit will be rewarded by both improved immediate postoperative outcomes and the long-term health benefits after surgery. This review will introduce basic concepts important to perioperative tobacco control and cover recent advances in the field. ⋯ The fact that the perioperative period represents an excellent opportunity to help surgical patients quit smoking is becoming increasingly apparent. Although these efforts, and the evidence base to support them, are still at an early stage of development, seizing this opportunity will benefit both the short and long-term health of our patients who smoke.

Regional analgesia for labor pain and general anesthesia for cesarean section in the morbidly obese parturient is associated with increased maternal and perinatal complications. The purpose of this review is to describe the anesthetic management of the morbidly obese parturient. ⋯ Early preoperative assessment, epidural insertion, and replacement for failed regional anesthesia/analgesia along with preparation for general anesthesia and difficult airway intubation is advocated to decrease potential complications in the morbidly obese parturient.

ReviewPremedication of the pediatric patient - anesthesia for the uncooperative child.
Inadequate handling of an uncooperative child preoperatively results in postoperative behavior problems. Premedication enables a calm induction and helps to decrease postoperative problems. Several premedicants will be covered in this review. ⋯ The benefits and disadvantages of new and older drugs should be weighed against each other, and decisions should be made according to the requirements of surgery, ward conditions and the severity of psychologic, developmental or mental disease. Further studies for the evaluation of the anxiolytic, sedative and antipsychotic drugs are still required.
