Background. The aim of this study was to evaluate the effects of mivacurium on the cerebrospinal fluid pressure (CSFP) in patients requiring muscle relaxation to facilitate mechanical ventilation and on the intracranial pressure (ICP) in patients undergoing neurosurgery.
Methods. Experimental design: prospective study. Setting: ICU in a hospital and operating room in a neurosurgery department at University. Patients: 12 patients, GCS 6-7, with a mean age of 62.6±6.2 were studied in ICU and 10 patients, ASA I-II, with a mean age of 58.6±6.4 were studied in the operating room. Interven-tions: all patients received mivacurium as single bolus dose of 0.2 mg/kg iv. Measurements: Heart rate, SAP, DAP and MAP were recorded at different times. In ICU CSFP was measured via a catheter in lumbar subarachnoid space and in operating room ICP was measured via an intraventricular catheter. CPP was evaluated as the difference between MAP and ICP. Statistical analysis was carried out using ANOVA for repeated measures and Bonferroni “t”- test and a value of p<0.05 was considered to be significant.
Results. Mivacurium was found not to influence or to increase ICP or CSFP. No significant changes in cardiocirculatory parameters were recorded in all patients.
Conclusions. In conclusion, mivacurium can be considered a suitable and manageable neuromuscular blocking drug in the management of patients with intracranial pathology.
