ABSTRACT
One hundred eighty-four cases of awake craniotomy in Xijing Hospital from September 2010 to June 2019 were retrospectively included in the study.Patients were divided into Asleep-Awake-Asleep (AAA) group and monitored anesthesia care (MAC) group.In AAA group, general anesthesia was used in the early arousal period, sedatives and analgesics were stopped during the arousal period, and the bispectral index (BIS) value was maintained at 60-80 in the late arousal period.In MAC group, dexmedetomidine and remifentanil were intravenously infused in the early arousal period, and the BIS value was maintained at 60-80 in the late arousal pericd.Dexmedetomidine and remifentanil infused were reduced or stopped according to the Observer′s Assessment of Altertness/Sedation score during the arousal period, so that the patient could be awakened at any time, and the BIS value was maintained at 60-80 in the late arousal period.Compared with AAA group, the consumption of local anesthetic and remifentanil was significantly decreased, the operation and anesthesia time was shortened, the requirement for rescue analgesia was decreased, mean arterial pressure, end-tidal pressure of carbon dioxide (P ETCO 2) and partial pressure of arterial carbon dioxide (PaCO 2) were increased and partial pressure of arterial oxygen (PaO 2) was decreased after laryngeal mask insertion or sedation, and heart rate and PaO 2 were decreased, P ETCO 2 and PaCO 2 were increased after awakening in group MAC ( P<0.05). There were no significant differences in anesthesia failure rate in the awake craniotomy, incidence of adverse events during the arousal period, intraoperative incidence of tachycardia/bradycardia and hypertension/hypotension, Observer′s Assessment of Alertness/Sedation score during the arousal period, rate of postoperative visual analogue scale score>5 after surgery, postoperative requirement for rescue analgesia, neurological deficit rate and rehabilitation discharge rate between the two groups ( P>0.05). Compared with those after laryngeal mask insertion or after sedation, mean arterial pressure, heart rate, P ETCO 2 and PaCO 2 were significantly increased, and PaO 2 was decreased after awakening in AAA group ( P<0.05), and no statistically significant change was found in the parameters mentioned above after awakening in MAC group ( P>0.05). In summary, MAC shortens the operation and anesthesia time, no artificial airway is required, and it is suitable for the short time and minor operation.AAA has a better hemodynamics and oxygenation in the early arousal period, but the patient′s stress is more obvious after awakening, and effective prevention and intervention are needed.
ABSTRACT
Objective To explore the clinical efficacy of endovenous laser ablation (EVLA) of great saphenous vein combined with foam sclerotherapy in the treatment of variceal ulcer of lower extremities (VULE).Methods Data of 19 patients (20 affected limbs) with VULE were analyzed retrospectively.EVLA combined with foam sclerotherapy was performed,and the clinical effect was observed.Results The treatment was successfully performed in 19 patients (20 affected limbs).Diameters of the ulcer was (2.30 ± 1.61) cm before operation and (0.90± 0.32) cm 2 weeks after operation,respectively (t=10.53,P＜0.01),and the ulcers healed from 7 days to 3 months after the surgery in 20 patients without recurrence.Conclusion EVLA of great saphenous vein combined with foam sclerotherapy has good clinical efficacy.
