Resurgence of combined intravenous Ketamine and regional anesthesia in pediatric ocular surgery in COVID-19 pandemic.

PURPOSE

The current pandemic of COVID-19 has made airway procedures like intubation and extubation, potential sources of virus transmission among health care workers. The aim of this work was to study the safety profile of combined ketamine and regional anesthesia in pediatric ocular surgeries during the COVID-19 pandemic.

METHODS

This prospective study included pediatric patients undergoing ocular surgery under general anesthesia from April to October 2020. Children were premedicated with oral midazolam (0.25-0.50 mg/kg) or intramuscular ketamine (7-10 mg/kg), ondensetron (0.1 mg/kg) and atropine (0.02 mg/kg). Anesthesia was achieved with intravenous ketamine (4-5 mg/kg) and local anesthesia (peribulbar block or local infiltration). The patient's vital signs were monitored. Serious complications and postoperative adverse reactions related to anesthesia were documented.

RESULTS

A total of 55 children (62 eyes) were operated. Lid tear was the most common surgical procedure performed [n = 18 (32.7%)]. Dose of ketamine needed ranged from 30 to 120 mg (66.67 ± 30.45). No intubation or resuscitation was needed. Four children complained of nausea and two needed an additional dose of intravenous ondansetron due to vomiting in the post-operative period. Incidence of postoperative nausea and vomiting was not affected by age, duration of surgery or dose of ketamine used (P > 0.05). There was no correlation between increase in pulse and dose of ketamine.

CONCLUSION

Combined ketamine and regional anesthesia is a safe and effective alternative to administer anesthesia in a child during ocular surgeries.
