Development of a pediatric anesthesia fellowship curriculum in Australasia by the Society for Pediatric Anesthesia of New Zealand and Australia (SPANZA) education sub committee.

There has been a recognized need to develop a curriculum for pediatric anesthesia training in Australia and New Zealand. The drivers are safe care for children, clear standards of care for children within and outside of quaternary centres, and clarity of the expertise and skill of the practitioner. Entrustable professional activities (EPAs) made up of multiple competencies and sub-competencies are useful for the description and assessment of contemporary medical education. We have developed an EPA-based curriculum that is not prescriptive in the number or range of EPAs that should be completed. Individuals can shape their learning and training to the EPAs that will support their ability to provide high-quality safe care in the wide variety of institutions that they may be employed in after their pediatric fellowship. Institutions can use the curriculum to describe the skill set required for their institution and location. This paper will explain the process behind the development of the Society for Pediatric Anesthesia in New Zealand and Australia (SPANZA) guidelines of a curriculum for pediatric anesthesia fellowship based on EPAs.

Anesthesia management of laser photocoagulation for retinopathy of prematurity. A retrospective review of perioperative adverse events.

AIMS: The aim of this study was to report the incidence of perioperative adverse events occurring in infants undergoing diode laser photocoagulation of retinopathy of prematurity and to identify clinical risk factors that may affect the incidence. METHODS: This was a retrospective study of anesthetic and medical records of premature infants who were treated in the neonatal intensive care unit or an operating theater with laser photocoagulation in our institution between January 2014 and December 2019. Infants less than 38 weeks post-menstrual age or less than 2000 grams were considered high risk for complications. Electronic medical records were evaluated for clinical and demographic characteristics, comorbidities, and perioperative complications of anesthesia. RESULTS: Sixty-one infants (39 males, 22 females) underwent 72 laser treatments. The mean gestational age was 25.3 weeks (SD 1.6), and mean birth weight was 730 grams (SD 202). At treatment, the mean postmenstrual age was 37.5 weeks (SD 2.7) and weight was 2320 g (SD 610). Laser therapy was performed in an operating theater in 66 procedures (91.7%) and in the neonatal unit in 6 cases (8.3%). Twenty-nine (40.3%) laser surgeries occurred outside normal week-day daytime operating hours. Intraoperative hypotension occurred in 12 procedures (16.7%) but was not significantly different in high-risk infants (16.1% vs 16.7% OR 0.94 P = .94) or in procedures performed in-hours (16.3% vs 17.2% OR 0.93 P = .91). Post-extubation apnea occurred in 21 procedures (29%) but was not significantly different in high-risk infants (29.0% vs 27.3% OR 0.98 P = .34) or in procedures performed in-hours (27.9% vs 31.1% OR 0.86 P = .77). Infants remained intubated at the end of the procedure in 58 (80.5%) cases and 29 (40.3%) remained ventilated more than 24 hours after the procedure. CONCLUSION: The incidence of perioperative adverse events was not associated with patient's age, current weight, timing, or location of the procedure. Extubating infants at the end of the procedure is however associated with a high rate of apneas and bradycardia, and consideration should be given to keeping low weight infants undergoing prolonged procedures out-of-hours intubated.

A method for ultrasonographic visualization and injection of the superior laryngeal nerve: volunteer study and cadaver simulation.

Superior laryngeal nerve block is a valuable technique for provision of upper airway anesthesia. In bilateral scans of 20 volunteers, we developed a technique for ultrasonographic visualization of the superior laryngeal nerve and key anatomical structures using a hockey stick-shaped 8 to 15 MHz transducer (HST15 to 8/20 linear probe, Ultrasonix, Richmond, BC, Canada). Subsequently, we simulated superior laryngeal nerve scanning and injection in bilateral injections in 2 cadavers. Ultrasound-guided in-plane advancement of a needle toward the superior laryngeal nerve and injection of 1 mL of green dye was achieved in all 4 attempts and confirmed by a postprocedural dissection performed by an anatomist. We conclude that ultrasound-guided superior laryngeal nerve block in humans may be feasible.
