A history of pediatric anesthesia: a tale of pioneers and equipment

Surgical operations at Massachusetts General Hospital in 1846 and 1847: Early impact of the discovery of anaesthesia

The introduction of anaesthesia on 16 October 1846 brought about tremendous changes in the discipline of surgery. We sought to determine whether the concept of painless surgery was accepted by practitioners and patients, and whether this led to an increase in frequency and variety of surgical operations performed. To study these changes, we analysed surgical records from Massachusetts General Hospital, Boston, Massachusetts (MGH) in the months surrounding the discovery of ether anaesthesia. Surgical records from MGH between 25 February 1846 and 14 March 1847 were examined, and the variables studied included number of operations, type of operations, patient demographics, complications and analgesics used, as well as comments made by surgeons. Immediately following the introduction of anaesthesia, MGH experienced a sizeable increase in the volume of surgical operations. This included a doubling in the percentage of female patients undergoing surgery. Orthopaedic procedures and amputations both increased in frequency, as did the number of surgeons operating. Several records indicated the presence of postoperative wound infection. Operations were still performed without anaesthesia. Following the introduction of ether anaesthesia in 1846, surgical volume increased, and more women underwent surgery. This suggests early acceptance of anaesthesia by patients and the medical profession. In an era prior to the introduction of antiseptic and aseptic techniques it is not surprising that wound infections were observed in several patients. We provide a glimpse of anaesthesia and surgery during the first few months after the first public demonstration of anaesthesia at MGH.

The history, current state and perspectives of aerosol therapy

Nebulization is a very effective method of drug administration. This technique has been popular since ancient times when inhalation of plants rich in tropane alkaloids with spasmolytic and analgesic effects was widely used. Undoubtedly, the invention of anasthesia in the 19th century had an influence on the development of this technique. It resulted in the search for devices that facilitated anasthesia such as pulveriser or hydronium. From the second half of the 21st century, when the first DPI and MDI inhalers were launched, the constant development of aerosol therapy has been noticed. This is due to the fact that nebulization, compared with other means of medicinal substance application (such as oral and intravenous routes of administration), is safer and it exhibits a positive dose/efficacy ratio connected to the reduction of the dose. It enables drugs administration through the lung and possesses very fast onset action. Therefore, various drugs prescribed in respiratory diseases (such as corticosteroids, β-agonists, anticholinergics) are present on the market in a form of an aerosol.

Anesthesia in the modern world of apps and technology: Implications and impact on wellness

Recent decades have seen an unprecedented leap in digital innovation, with far-reaching implications in healthcare. Anesthesiologists have historically championed the adoption of new technologies. However, the rapid evolution of these technologies has outpaced attempts at studying their potential impact on healthcare providers' well-being. This document introduces several categories of workplace technologies commonly encountered by the anesthesiologist. We examine examples of novel technology and the impact of these digital interventions on the anesthesiologist's well-being. We also review popular personalized technology aimed at improving wellness and the impact on well-being examined. Finally, technology acceptance models are introduced to improve technology adoption, which, when appropriately applied, may minimize the negative impacts of technology on anesthesiologists' well-being. Incorporating quantitative, serial assessments of well-being as part of technology implementation are proposed as a future direction for examining the wellness impact of technology on anesthesiologists.

Pediatric Anesthesia Specialty Societies and Multi-Institutional Collaborations

Pediatric anesthesiology is a subspecialty of anesthesiology that deals with the high-risk pediatric population. The specialty has made significant advancement in large collaborative efforts to study and increase patient safety, including the creation of international societies, a dedicated journal, special committees and interest groups, and multi-institution databases for research and quality improvement. Readily available resources were created to help with the education of future pediatric anesthesiologists as well as continuing medical education. Conclusions: Specialty societies and collaborations in pediatric anesthesia are crucial for continuous improvement in the care of children. They promote research, education, quality improvement, and advocacy at the local, national, and international level.

Laparoscopic-guided versus transincisional rectus sheath block for pediatric single-incision laparoscopic cholecystectomy: A randomized controlled trial

PURPOSE

The purpose of our study was to compare the effectiveness of transincisional (TI) versus laparoscopic-guided (LG) rectus sheath block (RSB) for pain control following pediatric single-incision laparoscopic cholecystectomy (SILC).

METHODS

Forty-eight patients 10-21 years old presenting to a single institution for SILC from 2015 to 2018 were randomized to TI or LG RSB. Apart from RSB technique, perioperative care protocols were identical between groups. Pain scores were assessed with validated measures upon arrival in the postanesthesia care unit (PACU) and at regular intervals until discharge. The patients and those assessing them were blinded to RSB technique. The primary outcome was pain score 60 min after PACU arrival. Secondary outcomes included pain scores throughout the PACU stay, opioids (reported as morphine milligram equivalents (MME) per kg bodyweight) administered in PACU, length of stay, outpatient pain scores and opioid use, and adverse events. Groups were compared on outcomes using t test and generalized estimating equations for continuous variables and Fisher's exact test for categorical variables with significance at α = 0.05.

RESULTS

Mean age of the 48 subjects was 15 years (range = 11-20). The majority (79%) were female. Indications for surgery included symptomatic cholelithiasis (n = 41), acute cholecystitis (n = 4), gallstone pancreatitis (n = 2) and choledocholithiasis (n = 1). Mean (standard deviation) operative time was 61 (±23) min overall. No statistically significant differences in demographics, indication, operative time, or intraoperative analgesia were observed between TI (n = 24) and LG (n = 24) groups. The mean 60-min pain score was 3.4 (±2.6) in the LG group versus 3.8 (±2.1) in the TI group (p = 0.573). No significant differences were detected between groups in overall PACU or outpatient pain scores, PACU or outpatient opioid use, length of stay, or incidence of complications. Overall, mean opioid use was 0.1 MME/kg in the PACU and 0.5 MME/kg in the outpatient setting. Mean postoperative length of stay was 0.2 day. There were no major complications.

CONCLUSION

Laparoscopic-guided rectus sheath block is not superior to transincisional rectus sheath block for pain control following pediatric single-incision laparoscopic cholecystectomy. The single-incision laparoscopic approach combined with rectus sheath block resulted in effective pain control, low opioid use, and expedited length of stay with no major complications.

Mortality in paediatric burns at the Women's and Children's Hospital (WCH), Adelaide, South Australia: 1960-2017

BACKGROUND

Burn injuries are the third leading cause of preventable death in children worldwide, resulting in over 100 000 annual hospitalisations. In the paediatric population, scalds are the commonest mechanism and burn injuries of greater than 40% total burn surface area (TBSA) are associated with a high mortality and morbidity rate.

AIMS

The aim of this study was to review mortality in paediatric burns in a tertiary burns centre over a 60-year period, providing an understanding of local causes of mortality and directing future clinical research.

METHODS

We reviewed data collected prospectively from patients treated for burn injuries at the WCH from 1960 to 2017. Data of age, gender, mechanism of injury and TBSA were collected. TBSA of 40% and greater were included in the study.

RESULTS

All patients with total burn surface area (TBSA) less than 40% survived. There were a total of 75 patients who sustained burns of or greater than 40% TBSA. Overall mortality was 34% (26 of 75) of which 24 occurred in the 1960s. Of the 21 patients who died of flame burn injuries, 12 of them were described as clothes catching alight from being in close proximity to the source of flame. Average length of stay for patients who did not survive was 7 days (1-26).

CONCLUSION

Mortality has since declined and the prognosis for survival good, even in TBSA of greater than 90%. The investigations in fabric flammability led by Dr Thomas Pressley and Mr Murray Clarke prompted the rewriting of Australian standards for production of children's clothing. This, in combination with advances in paediatric resuscitation, surgical techniques as well as wound care has improved survival rates and outcomes in extensive burn injuries. Future studies focus to see not only better survival rates, but also better aesthetic and functional outcomes in burn survivors.

Robert Emmett Farr (1875-1932): A pioneer of pediatric regional anesthesia

Surgeons influence the introduction and development of anesthesia in many ways. Robert Emmett Farr is frequently cited as the first to describe the use of brachial plexus anesthesia in children. A surgeon based in Minneapolis, Minnesota, he passionately believed that regional anesthesia was superior to general anesthesia for many surgical procedures. He wrote extensively promoting other regional techniques, including local infiltration of local anesthetics for pyloromyotomy and harelip repairs, as well as caudal blocks for lower abdominal procedures. Anesthesia texts from the early 1900's suggest that regional anesthesia was not popular as a reliable alternative to general anesthesia. Undeterred, Farr continued promoting his view that regional anesthesia was the future of surgery. We examine how Farr promoted regional anesthesia in children and adults, in a way changing surgical practice and improving clinical care. We also hope to highlight the other contributions to medicine made by this pioneer.

Fifty years of the American Academy of Pediatrics Section on Anesthesiology: a history of our specialty

The American Academy of Pediatrics Section on Anesthesiology and Pain Medicine celebrated its 50th Anniversary in 2015. The Section was one of the first and only subspecialty organizations in anesthesiology at the time. This special article will focus on the contributions of the Section to the practice of pediatric anesthesiology in the areas of advocacy, education and member contributions. In 1986, the Section created the Robert M. Smith Award to honor those members who had made significant advances in the practice of pediatric anesthesiology. It is named after one of the Section founders, an influential educator, inventor, and researcher in our field. We will focus the latter part of the article on the Robert M. Smith award winners to illustrate the contributions of the Section and its members to the development of the field of pediatric anesthesiology.

Early-life single-episode sevoflurane exposure impairs social behavior and cognition later in life

BACKGROUND

Single-episode anesthetic exposure is the most prevalent surgery-related incidence among young children in the United States. Although numerous studies have used animals to model the effects of neonatal anesthetics on behavioral changes later on in life, our understanding of the functional consequences to the developing brain in a comprehensive and clinically relevant manner is unclear.

METHODS

The volatile anesthetic, sevoflurane (sevo) was administered to C57BL6 postnatal day 7 (P7) mice in a 40% oxygen and 60% nitrogen gas mixture. In order to examine the effects of sevo alone on the developing brain in a clinically relevant manner, mice were exposed to an average of 2.38 ± 0.11% sevo for 2 h. No sevo (control) mice were treated in an identical manner without sevo exposure. Mice were examined for cognition and neuropsychiatric-like behavioral changes at 1-5 months of age.

RESULTS

Using the active place avoidance (APA) test and the novel object recognition (NOR) test, we demonstrated that P7 sevo-treated mice showed a deficit in learning and memory both during periadolescence and adulthood. We then employed a battery of neuropsychiatric-like behavioral tests to examine social interaction, communication, and repetitive behavior. Interestingly, compared to the no-sevo-treated group, sevo-treated mice showed significant reductions in the time interacting with a novel mouse (push-crawl and following), time and interaction in a chamber with a novel mouse, and time sniffing a novel social odor.

CONCLUSIONS

Our study established that single-episode, 2-h sevo treatment during early life impairs cognition later on in life. With this approach, we also observed neuropsychiatric-like behavior changes such as social interaction deficits in the sevo-treated mice. This study elucidated the effects of a clinically relevant single-episode sevo application, given during the neonatal period, on neurodevelopmental behavioral changes later on in life.

The development of a specialty: an interview with Dr. Mark C. Rogers, a pioneering pediatric intensivist

Dr. Mark C. Rogers (1942-), Professor of Anesthesiology, Critical Care Medicine, and Pediatrics at the Johns Hopkins University, was recruited by the Department of Pediatrics at Johns Hopkins Hospital in 1977 to become the first director of its pediatric intensive care unit. After the dean of the medical school appointed him to chair the Department of Anesthesia in 1979, Rogers changed the course and culture of the department. He renamed it the Department of Anesthesiology and Critical Care Medicine, and developed a long-term strategy of excellence in clinical care, research, and education. However, throughout this period, he never lost his connection to pediatric intensive care. He has made numerous contributions to pediatric critical care medicine through research and his authoritative textbook, Rogers' Textbook of Pediatric Intensive Care. He established a training programme that has produced a plethora of leaders, helped develop the pediatric critical care board examination, and initiated the first World Congress of Pediatric Intensive Care. Based on a series of interviews with Dr. Rogers, this article reviews his influential career and the impact he made on developing pediatric critical care as a specialty.

The development of pediatric critical care medicine at The Children's Hospital of Philadelphia: an interview with Dr. John J. 'Jack' Downes

Dr. John J. 'Jack' Downes (1930-), the anesthesiologist-in-chief at The Children's Hospital of Philadelphia (1972-1996), has made numerous contributions to pediatric anesthesia and critical care medicine through a broad spectrum of research on chronic respiratory failure, status asthmaticus, postoperative risks of apnea in premature infants, and home-assisted mechanical ventilation. However, his defining moment was in January 1967, when The Children's Hospital of Philadelphia inaugurated its pediatric intensive care unit--the first of its kind in North America. During his tenure, he and his colleagues trained an entire generation of pediatric anesthesiologists and intensivists and set a standard of care and professionalism that continues to the present day. Based on an interview with Dr. Downes, this article reviews a career that advanced pediatric anesthesia and critical care medicine and describes the development of that first pediatric intensive care unit at The Children's Hospital of Philadelphia.

The development of continuous positive airway pressure: an interview with Dr. George Gregory

George Gregory, M.D. (1934-), Professor Emeritus at the University of California, San Francisco, has made numerous contributions to neonatology and pediatric anesthesia through his research efforts and authoritative textbook, Gregory's Pediatric Anesthesia. However he identified his defining moment as the occasion he saved the life of an infant suffering from neonatal respiratory distress syndrome by using continuous positive airway pressure (CPAP) ventilation. The development of CPAP by Gregory revolutionized the treatment of premature infants with respiratory failure. Prior to the creation of this treatment, the mortality rate of neonates with respiratory distress syndrome was >50%. The innovation markedly improved the ventilation of infants with respiratory distress and led to significant improvements in survival rates. Based on an interview with Dr. Gregory, this article describes the discovery of CPAP and reviews his career in advancing pediatric anesthesia and critical care medicine.
