Comparative StudyComparative Study of Trigeminocardiac Reflex After Trigeminal Ganglion Compression During Total Intravenous Anesthesia.
Percutaneous compression of the trigeminal ganglion (PCTG) is an alternative surgical treatment for trigeminal neuralgia (TN). Manipulation of PCTG can lead to significant hemodynamic changes, which may increase the risk of cardiovascular complications. However, to our knowledge, few studies have focused on anesthesia experience during PCTG as treatment for TN so far. It was our primary focus on how to ensure the stability of hemodynamics during our clinical anesthesia experience. This study aimed to compare the study group (using sodium nitroprusside [SNP] as soon as the puncture began) with the control group (without using SNP as soon as the puncture began) to investigate cardiovascular parameters (systolic blood pressure [SBP], diastolic blood pressure [DBP], and heart rate [HR]) at 5 periods during total intravenous anesthesia. ⋯ The control group and the study group were not able to prevent bradycardia elicited during PTCG. Compared with control group, dramatic elevations of the systemic blood pressure can be prevented using intravenous drip SNP as soon as the puncture began during total intravenous anesthesia in the study group. Our findings verify that intravenous drip SNP is an effective method to control abrupt rise of blood pressure.

Comparative StudyComparison of Postoperative Volume Status and Hemodynamics Between Surgical Clipping and Endovascular Coiling in Patients After Subarachnoid Hemorrhage.
Recent clinical data suggest that postoperative hemodynamic profile and fluid management may differ in aneurysmal subarachnoid hemorrhage patients depending on the treatment option: surgical clipping or endovascular coiling. Our aim was to determine the differences in hemodynamic parameters between the 2 modalities using an advanced transpulmonary thermodilution technique. ⋯ Surgical clipping is associated with higher cardiac output and hypovolemia in the early postoperative stage and poorer preload responsiveness to volume therapy during the vasospasm risk period compared with endovascular coiling.
