Pediatric procedure‐related pain management is often incompletely understood, inadequately addressed, and critical in influencing a child's lifelong relationship with the larger healthcare community. We present a comprehensive review of infiltrative anesthetics, including a comparison of their mechanisms of action and relative safety and efficacy data to help guide clinical selection. We also describe the multimodal utilization of adjunct therapies—in series and in parallel—to support the optimization of pediatric periprocedural pain management, enhance the patient experience, and provide alternatives to sedation medication and general anesthesia. In this second of a two‐part series, we present a comprehensive review of infiltrative anesthetics, including a comparison of their mechanisms of action and relative safety and efficacy data to help guide clinical selection. We also describe the multimodal utilization of adjunct therapies—in series and in parallel—to support the optimization of pediatric periprocedural pain management, enhance the patient experience, and provide alternatives to sedation medication and general anesthesia.

Pediatric procedure‐related pain management is often incompletely understood, inadequately addressed, and critical in influencing a child's lifelong relationship with the larger health care community. We highlight the evolution of ethics and expectations around optimizing periprocedural pain management as a fundamental human right. We investigate the state‐of‐the‐art of topical anesthetics, reviewing their mechanisms of action and providing comparisons of their relative safety and efficacy data to help guide clinical selection. In total, this two‐part review offers a combination of conventional approaches and innovative techniques that should be used multimodally—in series and in parallel—to help optimize pain management and provide alternatives to sedation medication and general anesthesia.

To evaluate the effect of positive end-expiratory pressure ( PEEP) on sound propagation through injured lungs, we injected a multifrequency broad-band sound signal into the airway of eight anesthetized, intubated and mechanically ventilated pigs, while recording transmitted sound at three locations bilaterally on the chest wall. Oleic acid injections effected a severe pulmonary oedema predominately in the dependent lung regions, with an average increase in venous admixture from 19 ± 15 to 59 ± 14% ( P<0·001), and a reduction in dynamic respiratory system compliance from 34 ± 7 to 14 ± 4 ml cmH2O−1 ( P<0·001). A concomitant decrease in sound transit time was seen in the dependent lung regions ( P<0·05); no statistically significant change occurred in the lateral or non-dependent areas. The application of PEEP resulted in a decrease in venous admixture, increase in respiratory system compliance and return of the sound transit time to pre-injury levels in the dependent lung regions. Our results indicate that sound transmission velocity increases in lung tissue affected by permeability-type pulmonary oedema in a manner reversible during alveolar recruitment with PEEP.

Propylene glycol (PG) is a solvent commonly used in medications that, while benign at low doses, may cause toxicity in adults and children at high doses. We describe a case and the physiologic sequelae of propylene glycol toxicity manifested in a critically ill adolescent male with refractory myoclonic status epilepticus aggressively treated with multiple PG-containing medications (lorazepam, phenobarbital, and pentobarbital)—all within accepted dosing guidelines and a total daily PG exposure previously recognized to be safe. Hemodynamic measurements by bedside echocardiography during clinical toxicity are also reported. Clinicians should have a high index of suspicion for propylene glycol toxicity in patients treated with PG-containing medications even when the total PG exposure is lower than currently accepted limits.

Over the past decade, numerous preclinical and retrospective human studies have reported that the provision of anesthetic and sedative agents to infants and children may be associated with adverse neurodevelopmental outcomes. These data have gained widespread attention from professional and regulatory agencies, including the public at large. As such, pediatric anesthesiologists are being increasingly questioned by parents about the risks of anesthetic agents on their children's neurocognitive development. To impart a framework from which anesthesiologists may address the apprehensions of parents who actively bring up this issue, we review the data supporting anesthetic neurotoxicity and discuss its strengths and limitations. As many parents are not yet aware and do not actively raise these concerns, we also discuss whether such a conversation should be undertaken as a part of the consent process. [ABSTRACT FROM AUTHOR]
