RESUMO

Introduction Residual neuromuscular block, defined as a quantitatively measured train-of-four ratio (TOFr) <0.9, is common postoperatively. Using a pragmatic trial design, we hypothesized that qualitative and/or clinical assessment of neuromuscular block would inadequately detect residual block following antagonism with neostigmine or sugammadex. Method After IRB approval and written informed consent, 74 children (aged 2-17 years), undergoing elective surgery and receiving rocuronium, were prospectively enrolled in the study at Children's Hospital Colorado and Children's Healthcare of Atlanta. Routine clinical practice at both institutions consisted of clinical signs and/or qualitative assessment with peripheral nerve stimulators. Children at the Colorado hospital routinely received sugammadex antagonism; whereas children at the Atlanta hospital received neostigmine. Residual neuromuscular block was assessed postoperatively using quantitative electromyography. If TOFr was <0.9, patients received sugammadex until TOFr ≥0.9. Result Qualitative and clinical assessment failed to detect residual block in 29.7% of patients in the neostigmine reversal cohort (adjusted odds ratio (aOR) 29.8, 95% confidence interval (CI): 2.7 to 5,559.5, p-value = 0.002). No residual block was detected in the sugammadex reversal cohort. A correlation between increasing patient weight and incidence of postoperative residual block was observed in the neostigmine cohort (aOR 1.05, 95% CI: 1.02 to 1.10, p-value = 0.002). Conclusion Qualitative and/or clinical assessment of neuromuscular block inadequately detects residual block following neostigmine antagonism.

RESUMO

BACKGROUND: Although the package insert clearly states that "the safety and efficacy of sugammadex in pediatric patients have not been established," we hypothesized that sugammadex is used widely in pediatric anesthetic practice supplanting neostigmine as the primary drug for antagonizing neuromuscular blockade (NMB). Additionally, we sought to identify the determinants by which pediatric anesthesiologists choose reversal agents and if and how they assess NMB in their practice. Finally, because of sugammadex's effects on hormonal contraception, we sought to determine whether pediatric anesthesiologists counseled postmenarchal patients on the need for additional or alternative forms of contraception and the risk of unintended pregnancy in the perioperative period. METHODS: We e-mailed a questionnaire to all 3245 members of the Society of Pediatric Anesthesia (SPA) requesting demographic data and attitudes regarding use of NMB agents, monitoring, and antagonism practices. To address low initial response rates and quantify nonresponse bias, we sent a shortened follow-up survey to a randomly selected subsample (n = 75) of SPA members who did not initially respond. Response differences between the 2 cohorts were determined. RESULTS: Initial questionnaire response rate was 13% (419 of 3245). Overall, 163 respondents (38.9%; 95% confidence interval [CI], 34.2-43.8) used sugammadex as their primary reversal agent, and 106 (25.2%; 95% CI, 21.2-30.0) used it exclusively. Respondents with ≤5 years of practice used sugammadex as their primary reversal agent more often than those with ≥6 years of practice (odds ratio [OR]: 2.08; 95% CI, 1.31-3.31; P = .001). This increased utilization remained after controlling for institutional restriction and practice type (adjusted OR [aOR]: 2.20; 95% CI, 1.38-3.54; P = .001). Only 40% of practitioners always assess NMB (train-of-four), and use was inversely correlated with years of practice (Spearman ρ = -0.11, P = .04). Anesthesiologists who primarily used sugammadex assess NMB less routinely (OR: 0.56; 95% CI, 0.34-0.90; P = .01). A slim majority (52.8%) used sugammadex for pediatric postmenarchal girls; those with less experience used it more commonly (P < .001). Thirty-eight percent did not discuss its effects on hormonal contraception with the patient and/or family, independent of anesthesiologist experience (P = .33) and practice location (P = .38). No significant differences were seen in demographics or practice responses between initial and follow-up survey respondents. CONCLUSIONS: Sugammadex is commonly used in pediatric anesthesia, particularly among anesthesiologists with fewer years of practice. Failure to warn postmenarchal adolescents of its consequences may result in unintended pregnancies. Finally, pediatric anesthesia training programs should emphasize objective monitoring of NMB, particularly with sugammadex use.

RESUMO

BACKGROUND: Emergence agitation (EA) and negative postoperative behavioral changes (NPOBC) are common in children, although the etiology remains unclear. We investigated whether longer times under deep hypnosis as measured by Bispectral Index (BIS) monitoring would positively correlate with a greater incidence of EA in the PACU and a greater occurrence of NPOBC in children after discharge. METHODS: We enrolled 400 children, 1-12 years old, scheduled for dental procedures under general anesthesia. All children were induced with high concentration sevoflurane, and BIS monitoring was continuous from induction through recovery in the PACU. A BIS reading <45 was considered deep hypnosis. The presence of EA was assessed in the PACU using the Pediatric Anesthesia Emergence Delirium scale. NPOBC were assessed using the Post-Hospital Behavior Questionnaire, completed by parents 3-5 days postoperatively. Data were analyzed using logistic regression, with a P < 0.05 considered statistically significant. RESULTS: The incidence of EA was 27% (99/369), and the incidence of NPOBC was 8.8% (28/318). No significant differences in the incidence of EA or NPOBC were seen with respect to length of time under deep hypnosis as measured by a BIS value of <45. CONCLUSION: Our data revealed no significant correlation between the length of time under deep hypnosis (BIS < 45) and the incidence of EA or NPOBC. Within this population, these behavioral disturbances do not appear to be related to the length of time under a deep hypnotic state as measured by the BIS.
