ABSTRACT

After medical stabilization, several techniques are considered for anesthesia in the surgical intervention of post-tonsillectomy bleeding in children. Hypoxia during induction of general anesthesia occurs more frequently than aspiration for this population. While classical (apneic) rapid sequence induction and intubation with cricoid pressure still has a role, controlled rapid sequence induction and intubation that incorporates mask ventilation at low pressure (<12 cm H2O) before direct laryngoscopy under a deep plane of anesthesia is a viable alternative for cases of slow venous bleeding. Supplemental oxygen delivery during laryngoscopy to permit apneic oxygenation is a future trend in management. While the routine administration of tranexamic acid during tonsillectomy has not been shown to be of benefit, it may have a role in post-tonsillectomy hemorrhage with further study.

ABSTRACT

Dr. Emanuel Papper, the founding chairman of the Department of Anesthesiology at Columbia University, was passionate about research, training, and innovation. At an event held in his honor on March 20, 2021, experts came together to discuss the coronavirus disease 2019 (COVID-19) pandemic and its myriad challenges. Dr. Wellington Sun, MD, of Vaxcellerant LLC, an expert in infectious disease and vaccine research and development, presented a "Primer of COVID-19 vaccines for the perioperative physician." Operation Warp Speed was successful in producing multiple efficacious and safe vaccines for use in the United States and around the globe. Their development and authorization for emergency use occurred in an unprecedented timespan of <1 year. Technology such as V-SAFE has helped to accrue extensive postdevelopment safety data that will be utilized for licensure of these vaccines. The COVID-19 vaccine success is tempered by the knowledge that severe acute respiratory syndrome coronavirus 2 continues its natural selection of variants that threaten the efficacy of vaccines. Important questions remain regarding the future of the COVID-19 pandemic, severe acute respiratory syndrome coronavirus 2 variants, successful vaccination strategies, and preparedness for future pandemics.

ABSTRACT

BACKGROUND: Perianesthetic neurological adverse events are rare in children and have been studied in detail in the settings of cardiac surgery and regional anesthesia. Our study aims to characterize perianesthetic neurological adverse events in children in the setting of all types of surgery and diagnostic or interventional procedures, to evaluate anesthesia's role, and to identify factors amenable to prevention. METHODS: We conducted a retrospective study by reviewing all the anesthetic encounters reported in the Wake-Up Safe database between January 2010 and December 2017. RESULTS: The rate of perianesthetic neurological adverse events was 0.49 per 10 000 pediatric anesthetic encounters. The odds of NAE were significantly higher in children who were older than 6 months; had American Society of Anesthesiologists physical status (ASA PS) of 3, 4, or 5; or had American Society of Anesthesiologists Emergency (ASA E) status. Seizures were the most common NAE. Overall, 23 (18.1%) children with neurological adverse events died, and 33 (26%) experienced permanent or severe permanent harm. The risk of death was higher in infants and in children with ASA PS of 3, 4, or 5; ASA E status; preexisting neurological abnormality; or preexisting neurological deficit and in events associated with cardiac arrest or trauma. Anesthesia contributed to 24 (18.9%) events; patient disease was the primary causative factor in 95 (74.8%) adverse events, and 37 (29.1%) events were preventable, including 2 deaths. Preventable factors broadly included inadequate preoptimization, complications during airway management and central venous catheter placement, and suboptimal patient positioning. CONCLUSION: Perianesthetic neurological adverse events are rare in children and have a poor outcome. Our study has described pediatric perianesthetic neurological injury in detail and identified contributing factors that can be optimized during various phases of perianesthetic care. This information can be utilized during the informed consent process and to enhance the quality of care in children receiving anesthesia.

ABSTRACT

BACKGROUND: Wake Up Safe, a Patient Safety Organization founded by the Society for Pediatric Anesthesia, collects data on serious adverse events along with demographic data from all pediatric patients receiving anesthesia care at participating institutions. This report reviews all events occurring between 2010 and 2015 and focuses on common adverse events that are anesthesia-related. AIMS: Determine which adverse events were most common from 2010 to 2015 among participating Wake Up Safe institutions. Determine how many anesthesia-related events were deemed to be preventable. METHODS: This is a descriptive report. The Wake Up Safe registry data were queried on September 29, 2017. Institutions were included if they had complete demographic data and at least 5 adverse events per year reported. At that time, 19 out of 29 institutions had complete demographic data for events from 2010 to 2015. This study describes demographic data and adverse events from these nineteen institutions. Descriptive data were extracted, and event rate was calculated for each adverse event category. In events that were assessed as primarily related to anesthesia, further detailed analysis was performed. RESULTS: Of all reported adverse events (2544 events), the most common were cardiac arrests (646, 31.6%), respiratory complications (598, 29.2%), and medication events (345, 16.9%). Of all anesthesia-related events (612 events), medication events were the most common (239, 31.9%), followed by respiratory complications (181, 24.1%), and cardiac arrests (139, 18.5%). Overall, 85% of anesthesia-related serious adverse events were deemed somewhat or almost certainly preventable. CONCLUSIONS: The majority of anesthesia-related serious adverse events reported to the Wake Up Safe database are preventable. Medication events are the most common anesthesia-related adverse events. Innovations aimed at decreasing medication events may be the most impactful.

ABSTRACT

Clinical researchers studying the long-term neurocognitive effects of anesthetic and sedative agents on children continue to struggle with identifying a phenotype for anesthetic neurotoxicity, the window of vulnerability, and the toxicity threshold in terms of concentration and duration. The Sixth Biennial Pediatric Anesthesia Neurodevelopment Assessment (PANDA) symposium at Columbia University included a moderated poster presentation session where 4 investigators presented their latest contributions to the landscape of clinical anesthetic neurotoxicity research. A lack of standardization in the design of clinical studies in terms of age at exposure, duration and type of exposure, and outcome measures assessed were highlighted by all the investigators. Suggestions for the future direction of clinical trials included the implementation of more consistent study parameters and the employment of standardized neurocognitive testing and imaging before and after exposure to general anesthesia. Presentations covered a broad range of topics including the valid translation of preclinical studies to human subjects, the quantification of real-world exposures to anesthetic and sedative medications, and possible alternatives to these exposures.

ABSTRACT

During the second day of the Pediatric Anesthesia NeuroDevelopment Assessment (PANDA) symposium 2016, 3 invited speakers focused on future directions for the PANDA group. This session, entitled "The Way Forward," included 3 talks on how other groups have organized through public-private partnerships (ACTTION), obtained NIH funding, and how to better communicate a research message. Dr Robert H. Dworkin spoke on the mission of the Analgesic, Anesthetic, and Addiction Clinical Trial Translations, Innovations, Opportunities and Networks (ACTTION), which is a public-private partnership with the United States Food and Drug Administration that pushes forward research related to pain and analgesics. Dr Tracy King discussed National Institute of Health funding for future studies in neurocognitive development after exposure to anesthetics. Dr Sharon Hertz discussed how the PANDA group might better craft their message to the public regarding effects of analgesics on neurocognitive development. Through their talks, the above speakers provided a clear route for the way forward in regard to research, funding, and messaging for the PANDA group.

ABSTRACT

Nusinersen (ISIS-SMNRx or ISIS 396443) is an antisense oligonucleotide drug administered intrathecally to treat spinal muscular atrophy. We summarize lumbar puncture experience in children with spinal muscular atrophy during a phase 1 open-label study of nusinersen and its extension. During the studies, 73 lumbar punctures were performed in 28 patients 2 to 14 years of age with type 2/3 spinal muscular atrophy. No complications occurred in 50 (68%) lumbar punctures; in 23 (32%) procedures, adverse events were attributed to lumbar puncture. Most common adverse events were headache (n = 9), back pain (n = 9), and post-lumbar puncture syndrome (n = 8). In a subgroup analysis, adverse events were more frequent in older children, children with type 3 spinal muscular atrophy, and with a 21- or 22-gauge needle compared to a 24-gauge needle or smaller. Lumbar punctures were successfully performed in children with spinal muscular atrophy; lumbar puncture-related adverse event frequency was similar to that previously reported in children.

ABSTRACT

General anesthetics mitigate distress and exaggerated hemodynamic responses to pain and stressful stimulation, allowing surgery and diagnostic procedures to be performed worldwide in millions of children every year. Emerging studies, mainly carried out in early postnatal laboratory animals, demonstrate widespread neuronal elimination, alteration in neuronal circuitry, and long-term neurological disabilities following exposure to all commonly used sedatives and anesthetics. These findings have raised concerns among parents, anesthesiologists, neuroscientists, and government regulators about the safety of anesthetic drugs in children, especially infants. Accumulating evidence from epidemiological studies suggests an association between surgery with anesthesia in early childhood and subsequent behavioral and cognitive abnormalities. During the Fourth Pediatric Anesthesia NeuroDevelopmental Assessment (PANDA) symposium, a meeting attended by many stakeholders, the most recent findings in the field were presented and discussed. This review summarizes the current state of clinical research into the effects of anesthetic exposure in human brain development, addresses some of the difficulties in examining the phenomenon, and introduces the most recent clinical findings presented at the PANDA symposium. The unanimous consensus among participants was that additional preclinical and clinical research efforts are urgently required to address this important concern for child health.

ABSTRACT

OBJECTIVE: Pulmonary hypertension is commonly found in patients undergoing valvular surgery and can be worsened by cardiopulmonary bypass. Inhaled epoprostenol (prostacyclin) has been used for the treatment of pulmonary hypertension, but its effects compared with those of placebo on hemodynamics, oxygenation, echocardiographic examination, and platelet function have not been studied during cardiac surgery. METHODS: Twenty patients with pulmonary hypertension undergoing cardiac surgery were randomized in a double-blind study to receive inhaled epoprostenol (60 microg) or placebo. The inhalation occurred after induction of anesthesia and before surgical incision. The effects on left and right systolic and diastolic cardiac functions evaluated by means of pulmonary artery catheterization and transesophageal echocardiography, as well as oxygenation and platelet aggregation, were studied. RESULTS: Inhalation of epoprostenol significantly reduced indexed right ventricular stroke work from 10.7 +/- 4.57 g. m. m(-2) to 7.8 +/- 3.94 g. m. m(-2) (P =.003) and systolic pulmonary artery pressure from 48.4 +/- 18 mm Hg to 38.9 +/- 11.9 mm Hg (P =.002). The effect was correlated with the severity of pulmonary hypertension (r = 0.76, P =.01) and was no longer apparent after 25 minutes. There was no significant effect on systemic arterial pressures, left ventricular function, arterial oxygenation, platelet aggregation, and surgical blood loss. CONCLUSION: Inhaled epoprostenol reduces pulmonary pressure and improves right ventricular stroke work in patients with pulmonary hypertension undergoing cardiac surgery. A dose of 60 microg is hemodynamically safe, and its effect is completely reversed after 25 minutes. We did not observe any evidence of platelet dysfunction or an increase in surgical bleeding after administration of inhaled epoprostenol.
