[Perioperative blood gas analysis in 100 patients in spontaneous respiration treated with ND-YAG laser for endoluminal tracheo-bronchial neoplasms].
OBJECTIVE
To determine the reliability on spontaneous ventilation of small continuously associated doses of ketamine and propofol during yag-laser therapy for upper airways neoplastic obstructions.


METHODS
Prospective description of blood gas analysis variation throughout the intervention and in the early postoperative period.


METHODS
Operating theatre and postoperative Intensive Care Unit of the National Institute for Cancer Research.


METHODS
A hundred consecutive cancer patients referred to our Institution for upper airways tumoral progressive obstruction.


METHODS
Yag-laser firing.


RESULTS
Pre-intra and postoperative blood gas analysis, BP, HR, Sat O2 have been registered every 10'. Mean intraoperative pCO2 rose to 47.3 mmHg (30-60), but within 2 to 3.20 hrs returned close to preoperative value (38.3 mmHg) allowing early patient discharge.


CONCLUSIONS
The i.v. association of 0.7-1.0 mg/kg Ketamine and 1 mg/kg propofol, followed by 5 micrograms/kg/h and 3 mg/kg/h respectively, turned out to be satisfactory for both patients and anaesthetists in terms of anaesthesia and spontaneous breathing maintenance during yag-laser firing for obstructive upper airways cancer patients.
