Abstract

Although it is assumed that appropriate care of endoTRACHEAl tubes and airway might prevent POSTINTUBATION airway stenos is (PIAS), but this concept has not been investigated adequately. The purpose of the study was to investigate practical ways for prevention of PIAS in intubated patients. The study was implemented in 3 phases. First we collected information about methods of caring for airways and tubes in intensive care units in Tehran and other cities (control group) and data collection based on filling 10-20 questionnaires in each intensive care unit. Then we assessed patients who had PIAS had been and treated by us during a 6 year period (1994-2000) (study group). In the final phase, collected data were analyzed and we looked for important pitfalls in caring for airways in intensive care units in our country and also looked for the practical measures to prevent PIAS. In phase I, 341 questionnaires were filled out in 18 intensive care units (12 in Tehran, 6 in other cities). There were 133 females and 208 males aged 3 month to 98 years (mean 46.1). Head injury was the commonest cause of intubations in 24%. Of patients Out of 356 TRACHEAl tubes which had been used in these patients, 318 were high volume low pressure types (new tubes), and 32 were high pressure low volume types (old tubes). In 179 patients (52.4%), there was not any type of care for tubes and airways by attending physicians, in 140 patients (41%) there was some kind of care although not organized or sufficient and in only 21 patients (6.1%) the care was organized and sufficient. Mean time of intubation was 8 days (1-45 days). Tracheotomy had been undertaken without any established criteria and mostly by junior staff with low experience (usually junior residents(. In phase II, 120 patients were treated for PIAS (36 females, 84 males aging 1-83 years, mean 25.9 years). Head injury was the cause of intubation in 78(65%) patients, the site of stenos is was TRACHEAl in 88 and laryngoTRACHEAl in 32 patients. More than half of the patients were intubated by inappropriate old tubes. Direct cause of STENOSIS was the cuff in 92, tip of the tubes in 15 and stoma in 10 patients. In 3 patient's more than one factor were the causes. Mean time of intubation was 14.9 days (1-90) and mean length of stenos is was 3.2 cm (1-7). Caring of tubes and airways was inappropriate and in organized in all patients. Factors which were statistically different in study and control group were: time of intubation (14.9 day vs 8 days, P=0.000), suicide attempts (12 vs 5, P=0.000), head injuries (65%vs 24% P=0.000), Age (25.9y Vs 46y, P=0.05), using old tubes (50%vs 9% P=0.000), organized caring of tubes and airways (0.0%vs 6.1% P=0.000). The following measures are effective in decreasing the PIAS: decreasing time of intubation, using appropriate tubes, (including PVC tubes), continuous care of airway and tube, cuff monitoring and daily recording of information about tubes and cuff pressure, and special care for intubated young patients who had sustained head injury or had attempted suicide.
