The introduction of a new generation of inhaled anesthetics into pediatric clinical practice has been associated with a greater incidence of ED, a short-lived, but troublesome clinical phenomenon of uncertain etiology. A variety of anesthesia-, surgery-, patient-, and adjunct medication-related factors have been suggested to play a potential role in the development of such an event. Restless behavior upon emergence causes not only discomfort to the child, but also makes the caregivers and parents feel unhappy with the quality of recovery from anesthesia. Although the severity of agitation varies, it often requires additional nursing care, as well as treatment with analgesics or sedatives, which may delay discharge from hospital. To reduce the incidence of this adverse event, it is advisable to identify children at risk and take preventive measures, such as reducing preoperative anxiety, removing postoperative pain, and providing a quiet, stress-free environment for postanesthesia recovery. More clinical trials are needed to elucidate the cause as well as provide effective treatment.

The addition of fentanyl to local anesthetics improved the quality and prolonged the duration of cervical plexus block in patients undergoing CEA.

IntroductionCarotid endarterectomy may be performed under general (GA) or regional anesthesia (RA). The aim of this study was to evaluate the influence of anesthetic techniques on perioperative mortality and morbidity in patients undergoing carotid surgery.Material and methodsThis prospective study included 1098 consecutive patients operated on between 2003 and 2009 (773 underwent cervical plexus block and 325 underwent general anesthesia).ResultsThere were 6 deaths, 3 (0.9%) after GA and 3 (0.4%) after RA (p = 0.272). Neurological complication rates were not significantly different (GA 2.1% vs. RA 1.1%, p = 0.212). Incidence of myocardial infarction was similar (GA 0.31% vs. LA 0.39%, p = 0.840). Shunt placement rate was the same in both groups, 11.1%. Total operating time and carotid clamping time were significantly shorter in RA patients (RA: 92 min vs. GA: 106 min; p < 0.001 and RA: 18 min vs. GA: 19 min; p = 0.040). There was no significant difference in number of reinterventions (RA: 1.0% vs. GA: 0.6%; p = 0.504). Pulmonary complications were common in the GA group (RA: 0 vs. GA 0.9%; p = 0.007). Time to first postoperative analgesic was significantly shorter in the GA group (RA: 226 min vs. GA: 139 min; p < 0.001).ConclusionsType of anesthesia does not affect the outcome of surgical treatment of carotid disease. However, it should be stressed that fewer respiratory complications, later requirement for first postoperative analgesic, and an awake patient who can continue oral therapy early after surgery, give priority to regional techniques of anesthesia.

SummaryBackgroundThere has been only 1 study on postoperative pain after external dacryocystorhinostomy (DCR) that compared pain between 2 groups of patients; 1 group received local anesthesia and the other received general anesthesia. To further characterize the relationship between these 2 types of anesthesia and postoperative pain, we designed a study in which a single patient received these 2 different anesthesia modalities for a short interval on 2 different sides.Material/MethodsThere were 50 participants in this study. External DCR was performed on the same participant on both sides using local anesthesia on 1 side and general anesthesia on the other. Postoperative pain was measured using the visual analogue scale (VAS), and localization and timing of pain were reported by the participants. Postoperative nausea and vomiting (PONV) were documented if present.ResultsPain levels were significantly higher with general anesthesia 3 hours post-surgery, and 6 hours post-surgery the pain remains higher following general anesthesia but is borderline insignificant (p=0.051). However, 12 hours post-surgery, there is no significant difference in the pain level (p=0.240). There was no significant difference in the localization of pain with local and general anesthesia. Postoperative nausea is significantly more frequent after general anesthesia, and vomiting only occurs with general anesthesia. Local anesthesia was preferred by 94% of the participants (47 out of 50).ConclusionsThe vast majority of patients in our study who have undergone both GA and LA DCR would choose LA again, providing a compelling case for use of the LA technique.
