RESUMO
BACKGROUND: Practice patterns surrounding awake extubation of pediatric surgical patients remain largely undocumented. This study assessed the value of commonly used predictors of fitness for extubation to determine which were most salient in predicting successful extubation following emergence from general anesthesia with a volatile anesthetic in young children. METHODS: This prospective, observational study was performed in 600 children from 0 to 7 yr of age. The presence or absence of nine commonly used extubation criteria in children were recorded at the time of extubation including: facial grimace, eye opening, low end-tidal anesthetic concentration, spontaneous tidal volume greater than 5 ml/kg, conjugate gaze, purposeful movement, movement other than coughing, laryngeal stimulation test, and oxygen saturation. Extubations were graded as Successful, Intervention Required, or Major Intervention Required using a standard set of criteria. The Intervention Required and Major Intervention Required outcomes were combined as a single outcome for analysis of predictors of success. RESULTS: Successful extubation occurred in 92.7% (556 of 600) of cases. Facial grimace odds ratio, 1.93 (95% CI, 1.03 to 3.60; P = 0.039), purposeful movement odds ratio, 2.42 (95% CI, 1.14 to 5.12; P = 0.022), conjugate gaze odds ratio, 2.10 (95% CI, 1.14 to 4.01; P = 0.031), eye opening odds ratio, 4.44 (95% CI, 1.06 to 18.64; P= 0.042), and tidal volume greater than 5 ml/kg odds ratio, 2.66 (95% CI, 1.21 to 5.86; P = 0.015) were univariately associated with the Successful group. A stepwise increase in any one, in any order, of these five predictors being present, from one out of five and up to five out of five yielded an increasing positive predictive value for successful extubation of 88.3% (95% CI, 82.4 to 94.3), 88.4% (95% CI, 83.5 to 93.3), 96.3% (95% CI, 93.4 to 99.2), 97.4% (95% CI, 94.4 to 100), and 100% (95% CI, 90 to 100). CONCLUSIONS: Conjugate gaze, facial grimace, eye opening, purposeful movement, and tidal volume greater than 5 ml/kg were each individually associated with extubation success in pediatric surgical patients after volatile anesthetic. Further, the use of a multifactorial approach using these predictors, may lead to a more rational and robust approach to successful awake extubation.

INTRO: Pain management for minimally invasive (Nuss) repair of pectus excavatum (PE) is challenging, particularly as the judicious use of opioids has become a patient safety priority. Multi-modal pain management protocols are increasingly used, but there is limited experience using transdermal lidocaine patches (TLP) in this patient population. METHODS: Pediatric anesthesiologists and surgeons in a children's hospital within a hospital designed a multi-modal perioperative pain management protocol for patients undergoing Nuss repair of PE (IRB00068901). The protocol included use of TLP in addition to other adjuncts such as methadone, gabapentin, and NSAIDS. Following initiation of the protocol charts were reviewed retrospectively, comparing outcomes before and after implementation of the protocol. RESULTS: Forty-nine patients underwent a Nuss procedure between 2013 and 2022, 15 prior to initiation of the protocol and 34 after. Patient demographics and operative length were similar between the two groups. Average length of stay decreased from 4.7 to 3.3 days and reported opioid use at the time of the first outpatient post-op visit dropped from 60% to 24% (p < 0.05). Morphine milligram equivalents (MME) usage was decreased following implementation during hospital admission, at discharge, and at first post-operative visit (464 vs. 169, 1288 vs. 218, and 214 vs. 56, respectfully, p < 0.05). There were no ED visits or readmissions <30 days related to post-operative pain. CONCLUSION: Post-operative opioid usage and hospital length of stay were decreased after initiation of the protocol. Transdermal lidocaine patches may be a helpful adjunct to minimize narcotic requirements after repair of pectus excavatum. LEVEL OF EVIDENCE: Level II.
