The relationship between changes in BT and type of suction system (Pearson´s chi-square = 4.337; p = 0.362) was not statistically proven.
Similarly, we obtained statistically insignificant results by monitoring the onset of change in BT >38°C on individual days of hospitalization, which would implicate the type of suction system. Between the first and fourth day, of 49 patients who underwent CSS, BT > 38°C was measured in 31 patients.
