Objective To observe the respiratory depression of sufentanil with target-controlled infusion under propofol sedation or not.Methods40 patients, ASAⅠ or Ⅱ, scheduled for selective neurosurgery were randomly divided into the sufentanil group (group S) and the combined group (group SP) with 20 cases in each group. In the group SP, sedation was maintained with target-controlled infusion of propofol by plasmas concentration of 2 μg/ml. Target-controlled infusion of sufentanil was performed at the initial plasma concentration (Cp) of 0.2 ng/ml, and increased in a increment of 0.2 ng/ml at 3 minutes interval; while in the group S, only the infusion of sufentanil was performed. The respiratory rate (RR), minute ventilation (MV), partial pressure of end-tidal carbondioxide (PETCO2), pulse oxygen saturation (SpO2), mean arterial pressure (MAP), heart rate (HR), Observer's Assessment of Alertness/Sedation (OAA/S) were measured and respiratory depression was defined as one of the following end points were achieved: muscle rigidity, RR<6 bpm, MV<3 L/min, PETCO2>55 mmHg, SpO2<90% or apnea>15 s.ResultsThe RR, MV of patients in two groups decreased and PETCO2 increased significantly as increase of Ce ( P<0.05). The calculated effect site concentration (Ce) of sufentanil for respiratory depression was (0.46±0.14)ng/ml in the group S and (0.23±0.06)ng/ml in the group SP having a significant difference between two groups ( P<0.01).ConclusionSufentanil can dose-dependently suppress spontaneous respiration.

Objective To report a case of continuous positive airway pressure (CPAP) treatment for obstructive sleep apnea (OSA) combined with idiopathic intracranial hypertension (IIH) and review the relationship between the IIH and OSA. Methods A case of increased intracranial pressure in a middle-aged male patient who was diagnosed as IIH after the MRI and angiography ruled out intracranial lesions was reported. This patient presented with drowsiness, obesity and other symptoms. An overnight polysomnography (PSG) confirmed severe OSA. The simple use of intracranial pressure lowering therapy could not achieve sustained effective control of symptoms of high intracranial pressure. The clinical effects of comprehensive treatment for the OSA including CPAP and weight loss were observed. Results After 3 months treatment, the body mass index of this patient dropped from 35.7 to 31.4, apnea hypopnea index dropped from 72.6 to 10. 1, and the minimum SaO2 increased from 67% to 82%. And the symptoms of high intracranial pressure including headache and papillaedema were continuously improved. Conclusion Sleep apnea is a risk factor for IIH, especially for obese male patients. PSG monitoring could help us to find the important but easily overlooked factor of OSA. Taking active measures to treat OSA can effectively relieve the high intracranial pressure symptoms in patients with IIH.
