UnlabelledThe study is designed to evaluate the influence of remifentanil/propofol anesthesia on ventilator-associated pneumonia (VAP) occurrence and respiratory support (RS) time after major cardiac surgery.Material And MethodsIn retrospective-prospective study we investigated the respiratory support time and VAP occurrence in group of 47 patients with remifentanil/propofol and 35 patients with fentanil/midazolam anesthesia after major cardiac surgery in period June 2009-December 2011. Groups are divided in subgroups depending of who underwent cardiac surgery with or without cardiopulmonary by pass (CPB).ResultsThe time of respiratory support (RS) was the shortest in remifentanil group without CPB (R/Off 63min ± 44.3 vs R/On 94min ± 49.2 p=0,22), but was longer in fentanil group (F/Off 142 min ± 102.2 vs F/On 212 min ± 102.2 p=0.0014). The duration of RS of ON pump remifentanil group was shorter than in ON pump fentanil group (R/On 94 min vs F/On 212 min p=0.0011). The time of RS of OFF pump remifentanil group was lower than in Off pump entangle group (R/Off 63min ± 44,3 vs F/Off 142min ± 102.2 p=0,021) with statistically significance. Ventilator-associated pneumonia was detected in 7 patients (8.5 %). Six patients (17.1%) were from entangle group and one patient (2.1%) from remifentanil group. The most common isolates were Pseudomonas aeruginosa in all patients and both Pseudomonas aeruginosa and Klebsiella pneumonia in one patient.ConclusionThe remifentanil anesthesia regimen in cardiac surgery decreases length of respiratory support duration and can prevent development of VAP. The role of remifentanil anesthesia in preventing VAP, as one of the most important risk factor of in-hospital mortality after cardiac surgery is still incompletely understood and should be investigated further.
