Statistical significance in comparison with T1 is shown. *P <0.05; **P <0.01.Figure 4A significant increase of blood flow velocity in the middle cerebral artery (mV MCA) was observed in the control group. Statistical significance in comparison with T1 is shown. *P <0.05.Figure 5SjO2 increased after endotracheal suctioning (ETS) in both groups. In the control group a significant difference was observed. Statistical significance in comparison with T1 is shown. *P <0.05.
Figure 6Cough score evaluated immediately after endotracheal suctioning (ETS) is proven . Every single bar corresponds to your cough score of every patient.These adjustments weren't sustained over time. As in contrast with T1, 10?minutes immediately after ETS (T5) HR (from 74.3��14.0 to 78.0��20.four?min-1; P=0.17), MAP (from 89.0��11.six to 88.8��11.0?mmHg; P=0.92), ICP (from eleven.0��6.7 to eleven.4��7.4?mmHg; P=0.61) and SjO2 (from 82.3��7.five to 85.1��6.0%; P=0.13) weren't modified; mV MCA enhanced (from 76.8��20.4 to 84.6��24.two; P=0.03) (Figures?one, ?,two,2, ?,three,three, ?,44 and ?and55).InterventionNo important variation of HR, MAP, CPP, mV MCA, and SjO2 were observed in any phase throughout the examine. At baseline (T1) ICP was eleven.0��6.4?mmHg; at this phase, in two circumstances it had been higher than twenty?mmHg. Following ketamine administration (T2), ICP didn't modify (eleven.
7��7.3 vs. eleven.0��6.4?mmHg; P=0.28); just after ETS (T3) cough reflex was considerably decreased in comparison with controls (cough score 4 (IQR three to four) vs. two (IQR1 to 2); P <0.0001) (Figure?6). ICP increased after ETS if compared with T1 (15.1��9.4 vs. 11.0��6.4?mmHg; P <0.05). (Figures?1, ?,2,2, ?,3,3, ?,44 and ?and5).5). Interestingly, in contrast with controls, ETS did not induce any significant change of mV MCA and SjO2.DiscussionThe main result of this study is that the administration of a racemic mixture of ketamine did not induce any significant variation of ICP, CPP, MAP, mV MCA and SjO2 in mechanically ventilated head-injured patients during continuous analgosedation. If administered before ETS, racemic ketamine reduced cough reflex, and prevented any significant change of MAP, CPP, mV MCA and SjO2 in comparison with controls.
Nonetheless, its use just before ETS was not enough to fully blunt ICP increases at the drug dose studied.Ketamine is historically contraindicated for its use in sufferers with head injury, considering that an association with improved ICP was reported [17-21]. This concept originated from a handful of case reports and small case�Ccontrol studies through the 1970s carried out on sufferers with abnormal cerebrospinal fluid pathways.
