Postoperative emergence agitation and intraoperative sevoflurane sedation under caudal block in children: a randomized comparison of two sevoflurane doses.

ABSTRACT:

Background

Sub-umbilical surgery under caudal block in conjunction with sevoflurane sedation may be safe in terms of maintaining spontaneous breathing and avoiding complications associated with general anesthesia. However, sevoflurane-induced emergence agitation (EA) continues to be a clinically important phenomenon in children. To compare the incidence of EA in children undergoing sub-umbilical surgery under caudal block with two different doses of sevoflurane.

Methods

Forty children (aged 1-5 years) scheduled to undergo inguinal hernia repair under caudal block with sevoflurane sedation via a face mask were randomized into either the low-dose (1.0%) end-tidal sevoflurane concentration group (Group LS) or the high-dose (2.5%) end-tidal sevoflurane concentration group (Group HS). We monitored EA episodes at 5 and 30 min in the post-anesthetic care unit (PACU) by using the fourpoint agitation scale and the Pediatric Anesthesia Emergence Delirium (PAED) scale.

Results

The four-point agitation scale scores and PAED scores were not different between the groups at 5 min. However, the agitation score was higher in Group HS than in Group LS at 30 min after arriving in the PACU. The time required to recover from sedation was longer in Group HS than in Group LS.

Conclusions

Face-mask sedation with 1.0% sevoflurane in conjunction with caudal block may be more effective than that with 2.5% sevoflurane in preventing EA.

Project description:BackgroundThe differences in the incidence and severity of emergence agitation (EA) and emergence times between desflurane and sevoflurane anesthesia have not been as clearly elucidated in children as in adults.MethodsThe design of the study is a systematic review with meta-analysis of randomized controlled trials. The study methodology is based on the Cochrane Review Methods. A comprehensive literature search was conducted to identify clinical trials comparing the incidence or severity of EA and emergence times in children anesthetized with desflurane or sevoflurane. Two reviewers independently assessed each study according to predefined inclusion criteria and extracted data from each study using a prespecified data extraction form. The data from each study were combined using a fixed effect or random effect model to calculate the pooled risk ratio (RR) or standardized mean difference (SMD) and 95% confidence interval (CI). Funnel plots were used to assess publication bias. Subgroup and sensitivity analyses were performed.ResultsFourteen studies met the inclusion criteria. Among the 1196 patients in these 14 studies, 588 received desflurane anesthesia and 608 received sevoflurane anesthesia. The incidence of EA was comparable between the 2 groups (pooled RR = 1.21; 95% CI: 0.96-1.53; I = 26%), and so was the severity of EA (EA score) between the 2 groups (SMD = 0.12; 95% CI: -0.02 to 0.27; I = 0%). Extubation and awakening times were shorter in the desflurane group than in the sevoflurane group; the weighted mean differences were -2.21 (95% CI: -3.62 to -0.81; I = 93%) and -2.74 (95% CI: -3.80 to -1.69; I = 85%), respectively. No publication bias was found in the funnel plot. The subgroup analysis based on the type of EA scale showed a higher incidence of EA in the desflurane group than in the sevoflurane group in studies using 3-, 4-, or 5-point EA scales; the pooled RR was 1.38 (95% CI: 1.10-1.73; I = 37%).ConclusionThe incidence and severity of EA were comparable between desflurane and sevoflurane anesthesia in children; however, emergence times, including extubation and awakening times, were shorter in desflurane anesthesia.

Project description:The aim of the present study was to observe whether dexmedetomidine (DEX) combined with sufentanil decreased emergence agitation (EA) in children receiving sevoflurane anesthesia for cleft palate repair surgery. Children undergoing elective cleft palate repair surgery were randomly allocated into the DEX + sufentanil group (group DS; n=50) and the normal saline + fentanyl group (group SF; n=50). Patients in group DS were treated with 0.5 µg/kg DEX prior to induction of anesthesia, whereas patients in group SF received an equal volume of normal saline. Sufentanil (0.2 µg/kg) was administered to induce anesthesia, and 30 min before the end of surgery for patients in group DS. Fentanyl (2 µg/kg) was administered at the same time point for patients in group SF. Mean arterial pressure (MAP), heart rate (HR), duration of surgery and anesthesia, and the dosage of remifentanil were assessed. EA score, Pediatric Anesthesia Emergence Delirium (PAED) score and the Children and Infants Postoperative Pain Scale (CHIPPS) score were documented every 15 min in the post-anesthesia care unit (PACU). The number of cases requiring fentanyl (1 µg/kg) and the recovery profile data were analyzed. Compared with group DS (P<0.05) and the baseline (P<0.05), HR and MAP were significantly increased in group SF immediately following tracheal intubation and extubation. Mean values of maximum EA, PAED and CHIPPS scores were significantly reduced in group DS compared with group SF at 0 (P<0.01), 15 (P<0.05), and 30 min (P<0.05) after arrival at PACU. The incidence of EA in group SF was significantly increased compared with group DS (P<0.05). The dosage of remifentanil during the surgery and the number of cases requiring fentanyl (1 µg/kg) in group DS were significantly decreased compared with group SF (P<0.05). The findings of the present study suggested that DEX combined with sufentanil was able to effectively decrease the incidence of EA in children receiving sevoflurane anesthesia for cleft palate repair surgery.

Project description:The objective of this article is to evaluate the effect of dexmedetomidine on emergence agitation (EA) and recovery profiles in children after sevoflurane anesthesia and its pharmacological mechanisms. Standard bibliographic databases, including MEDLINE, EMBASE, PsycINFP, Springer and ISI Web of Knowledge, were artificially searched to identify all randomized controlled trials (RCTs) comparing the impact of dexmedetomidine with placebo, fentanyl and midazolam on EA and recovery profiles after sevoflurane anesthesia in post-anesthesia care unit (PACU). Two authors assessed the quality of each study independently in accordance with strict inclusion criteria and extracted data. RevMan 5.0 software was applied for performing statistic analysis. The outcomes analyzed included: 1) incidence of EA, 2) emergence time, 3) time to extubation, 4) incidence of post-operation nausea and vomiting, 5) number of patients requiring an analgesic, and 6) time to discharge from PACU. A total of 1364 patients (696 in the dexmedetomidine group and 668 in the placebo, fentanyl and midazolam group) from 20 prospective RCTs were included in the meta-analysis. Compared with placebo, dexmedetomidine decreased the incidence of EA (risk ratio [RR] 0.37; 95% CI 0.30 to 0.46), incidence of nausea and vomiting (RR 0.57; 95% CI 0.38 to 0.85) and number of patients requiring an analgesic (RR 0.43; 95% CI 0.31 to 0.59). However, dexmedetomidine had a significantly delayed effect on the emergence time (weighted mean differences [WMD] 1.16; 95% CI 0.72 to 1.60), time to extubation (WMD 0.61; 95% CI 0.27 to 0.95), and time to discharge from recovery room (WMD 2.67; 95% CI 0.95 to 4.39). Compared with fentanyl (RR 1.39; 95% CI 0.78 to 2.48) and midazolam (RR 1.12; 95% CI 0.54 to 2.35), dexmedetomidine has no significantly difference on the incidence of EA. However, the analgesia effect of dexmedetomidine on postoperation pain has no significantly statistical differences compared with fentanyl (RR 1.12; 95% CI 0.66 to 1.91), which implied that its analgesia effect might play an important role in decreasing the incident of EA. No evidence of publication bias was observed.
