DearEditor,
We read with great interest the article of Duran et al.1
concerningtiming ofpercutaneous tracheotomies inadult intensive care unit.Wecongratulatethem onthe presen-tationofthearticle.However,wewouldliketoaddsome comments.
Tracheotomy is a common procedure for patients who requireprolongedventilation.Itmaybebeneficialby lower-ingairwayresistance,improvingoralhygiene,andimproving pulmonary toilet and airway security and may also be associated withless sedative administration, less timeof sedation,enhancedpatientcomfort,andfewerpulmonary infections.2
Weagreewithauthoraboutthatearlypercutaneous tra-cheotomies shorten mechanical ventilation time,ICU and hospital stay times and result in less damage to the air-ways.Studiesshowedtheefficiencyofearlytracheotomyon mechanicalventilationtime,ICUstaytimesandpreventing the airwaydamage in critically illpatients. However, the optimaltiming(earlyvs.late)ofthetracheotomyin criti-callyillpatientsrequiringprolongedMVremainsunclear.3
The National Association of Medical Directors of Res-piratory Care recommended that tracheotomy should replace endotracheal intubation in patients who still require mechanical ventilation 3 weeks after admis-sion; and noted that identification of the optimal time for a tracheotomy to be performed is one of the most important criteria when deciding to perform the procedure.4
Analyses of some study groups showed that the rates andtimingoftracheotomyvariedsignificantlyacrossICUs.5
Apreconceivedopinion ofefficacy (in theabsenceof any evidence to support an optimal time for a tracheotomy) hasbeenarguedforexplainingthisincompatibilitybetween thewidespreaduseoftracheotomyanditsincoherentand non-homogenousclinicaluse.6Thismaybeofparticular
clin-icalimportancebecausepatientsreceiving atracheotomy requirealarge amount ofcare resourcesafterthe proce-dure.
Weobservenoticeableheterogeneityinthisstudy.This heterogeneitycouldbe associatedbydifferent numberof patient and illness in two groups. We think that patient condition and severity of illness may affect tracheotomy timingandoutcomes.Thusgroups formedshouldbemore homogenous.
