Abstract

Background:

Anaesthetic management of upper airway surgery in paediatric is challenging. Total intravenous anaesthesia with opioid or inhalation technique with spontaneous respiration has been used but studies are limited on inhalation technique. This study aimed to use tubeless inhalation insufflation technique without opioids at a tertiary centre.

Methods:

All paediatric patients coming for elective upper airway surgery to the centre, were included. Mask induction was with 5-8% sevoflurane in O2 and maintenance with 2-3%, via a nasopharyngeally placed Endotracheal Tube (ETT) or catheter on spontaneous ventilation with flow between 8-10 l/min. Lidocaine up to 5 mg/kg was then sprayed to the mucosa of larynx and trachea. Once adequate depth was attained, suspension laryngoscope was placed by a surgeon for surgery. Some complications were observed i.e inadequate anaesthesia requiring rescue drugs like opioids or propofol, intubation, desaturation events from laryngospasm and delayed recovery. Surgical technique involved was diagnostic and therapeutic for the upper airway lesions.

Results:

Fifteen paediatric patients (2 months to 7 yrs) were included in the study with tubeless anaesthesia. None of them required intubation during the procedure. The mean time from induction of anaesthesia to unconsciousness was 15 ± 3 s and attainment of necessary anaesthetic depth for surgery was 4.7 ± 0.90 min. None had desaturation events or required opioids. However, propofol was required in one and delayed anaesthetic recovery was observed in one patient.

Conclusion:

This study on tubeless anaesthesia with Local Anaesthetic (LA) spray with spontaneous inhalation insufflation technique provided an opioid-free, interference-free operative field without airway compromise, not requiring intubation, therefore, further studies are required.

Keywords: Anaesthetic technique, Inhalational, Airway management, Suspension laryngoscopy, Upper airway, Opioid.

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
(Westat, USA)

"Not only do open access journals greatly improve the access to high quality information for scientists in the developing world, it also provides extra exposure for our papers."
