Laryngoscopy for Neonatal and Infant aIrway Management (Optimise-Trial) — Optimise  

Airway Management Clinical Trial

Official title: Laryngoscopy for Neonatal and Infant aIrway Management wIth Supplemental oxygEn (OPTIMISE): a Multi-center Prospective Randomized Controlled Trial

Status Completed

Clinical Trial Summary

The objective of this study is to compare tracheal intubation first attempt success rate with the C-MAC indirect videolaryngoscope (Karl Storz, Germany) using a Miller-Blade nr 0 or nr 1 compared to a standard direct laryngoscope with standard blades Miller nr 0 and Miller nr 1 with oxygen supplementation either in the operating room or intensive care to demonstrate that with oxygen supplementation the difference in the first-attempt success rate in favor of VL is negligible

Clinical Trial Description

Eligible children will be prepared for intubation according to the local SOPs of the pediatric anesthesia or pediatric intensive care departments. Mandatory monitoring will consist of: SpO2, HR, NIBP. Induction of anesthesia: All children included in this protocol will be pre-oxygenated before induction of anesthesia for one minute through face-mask with FiO2 = 1.0 and flow rates of 6-10L/min. The induction of anesthesia for tracheal intubation will be performed using a combination of sedative/hypnotic drugs, opioids and non-depolarizing muscle relaxant. The following medications will be mandatory as per protocol: - A non-depolarizing muscle relaxant (NDMR) drug (Rocuronium 0.5-1 mg/kg, Cis-Atracurium 0.2-0.5 mg/kg, Vecuronium 0.1 mg/kg, or succinylcholine 2 mg/kg). - One or more of the following hypnotic agents (Thiopentone 4-7 mg/kg, Ketamine 0.5-2 mg/kg, Propofol 1-4 mg/kg, Midazolam 0.5-1 mg/kg, Sevoflurane up to 8%). An opioid drug and anticholinergic can be chosen and administered at the discretion of the anesthetist in charge Before intubation: After induction of anesthesia and the administration of a muscle relaxant drug, bag-mask ventilation with FiO2 = 1.0 (flow rates of 6-10 Lmin-1) will be performed for 60 seconds until apnea sets in. After induction all patients will be paralysed with e.g. 0.5-1 mg/kg of rocuronium (2 x ED95 (standard intubation dose)) to facilitate airway management. Neuromuscular blockade will be assessed by train-of-four (TOF) monitoring. Thereafter oxygen administration, laryngoscopy and tracheal intubation are performed. During intubation: The administration of oxygen during intubation is mandatory for every study participant and is standardized as follows: - Oral intubation: For all orally intubated children, the administration of low-flow oxygen (1 l/kg/min) takes place via conventional neonatal nasal cannula. After administration of low-flow oxygen laryngoscopy and tracheal intubation are performed. - Nasal intubation: For all nasally intubated children, the administration of low-flow oxygen (1 l/kg/min) takes place direct via nasal tube. The nasal tube is introduced into one of the two nostrils up to the nasopharyngeal space and oxygen is applied to the tube via oxygen cannula. After administration of low-flow oxygen laryngoscopy and tracheal intubation are performed. For a premature neonate < 1kg an uncuffed tube ID 2.5 will be used. For premature babies and newborn between 1kg and 3.0 kg an uncuffed tube ID 3.0 will be used. For babies > 3.0 kg a cuffed tube ID 3.0 or an uncuffed tube 3.5 will be used. The tube will be either passed through one of the two nostrils and advanced with the help of a Magill-forceps or through the mouth. Based on the group of randomization, the child will be intubated either using the C-MAC videolaryngoscope with a Miller blade 1 (Karl Storz, Germany) or using standard direct laryngoscope, with standard blades Miller nr 0 and Miller nr 1. Miller blade nr 0 will be used for children < 1 kg. In cases of unexpected difficult intubation, the difficult airway algorithm (14) will be followed. After the first unsuccessful intubation attempt with the randomized device, the investigators encourage to perform a second attempt with the same device but based on the clinical judgment the intubating physician can proceed to an attempt with the same technique, or change the laryngoscope blade size, switch from one technique to another and a maximum of 4 intubation attempts in total will be performed. The last intubation attempt must be performed by the most experienced physician in the room. Additional devices like stylet, bougie, etc, can be used at any stage of the intubation process. If the intubation remains unsuccessful the difficult airway algorithm will be followed and a supraglottic airway device - SAD will be inserted. ;
