An assessment of interrater reliability of the ASA physical status classification in pediatric surgical patients.
The American Society of Anesthesiologists physical status classification (ASA-PS) is used worldwide by anesthesia providers as an assessment of the preoperative physical status of patients. This assessment score has been inconsistently assigned by anesthesia providers among adult surgical patients. This study tested the reliability of assignment of ASA-PS classification among pediatric anesthesia providers. ⋯ These findings suggest a moderate agreement among pediatric anesthesia providers in assigning ASA-PS classification to selected pediatric case scenarios. Most disagreement, however, represented a tendency of outside care providers to assign a higher ASA physical status for cases. Furthermore, agreement was excellent for low risk (i.e. ASA I and II) as well as high risk (ASA III and IV) cases.

Randomized Controlled TrialCaudal 0.2% ropivacaine is less effective during surgery than 0.2% levobupivacaine and 0.2% bupivacaine: a double-blind, randomized, controlled trial.
We hypothesized that without the analgesic effects of volatile anesthetics, caudal 0.20% ropivacaine would be less effective during surgical stimulation than 0.20% bupivacaine or 0.20% levobupivacaine. This trial was designed to examine whether the combination of a caudal block with 0.20% ropivacaine and i.v. anesthesia resulted in reduced analgesic efficacy during surgery compared with caudal 0.20% levobupivacaine or 0.20% bupivacaine in children. ⋯ Combined with propofol anesthesia, 0.2% levobupivacaine and 0.2% bupivacaine are more effective than 0.2% ropivacaine for caudal use in children undergoing inguinal hernia repair or orchidopexy.

Randomized Controlled TrialAssociation of oculocardiac reflex and postoperative nausea and vomiting in strabismus surgery in children anesthetized with halothane and nitrous oxide.
Postoperative nausea and vomiting (PONV) occurs frequently after strabismus surgery. The controversy still exists regarding the association of PONV and the oculocardiac reflex (OCR). A recent study has proven that rocuronium attenuates OCR. If these two occurrences are dependent, it is expected that with the diminution of OCR, occurrence of PONV will also be reduced. The goal of this randomized, controlled study was to prove an association between OCR and PONV by attenuating OCR with 0.4 mg x kg(-1) of rocuronium and subsequently diminishing PONV if these occurrences are associated. ⋯ Rocuronium (0.4 mg x kg(-1)) attenuates the occurrence of OCR, but with the reduced occurrence of OCR we were not able to attenuate the occurrence of PONV, therefore the association of OCR and PONV in strabismus surgery in children anesthetized with halothane and nitrous oxide remains unclear, and if there is a link between the two, it could be related to arrhythmias and not bradycardia.

ReviewHead and neck blocks in children: an anatomical and procedural review.
Children undergo a variety of neurosurgical, otorhinolaryngology and plastic surgery procedures to the head and neck. Although opioids are utilized for pain control, they are associated with adverse side effects including postoperative nausea and vomiting, respiratory depression, somnolence and itching. The utilization of peripheral nerve blocks provides analgesia while reducing the need for opioids. This review will provide a summary of a variety of commonly used head and neck nerve blocks in children with a brief anatomical and technical summary.
