Comparison of costs of combined intravenous and inhalation general anesthesia and total intravenous anesthesia / 中国康复理论与实践

@#ObjectiveTo compare costs of combined intravenous and inhalation anesthesia (CIIA) and total intravenous anesthesia (TIA) when lower limbs orthopedics (LLO) performed on cerebral palsy children (CPC).MethodsTo analyze data of 49 CPC who received LLO under CIIA and TIA,and compare costs of two anesthetic styles.ResultsTIA had a significantly lower cost than CIIA (P<0.001),and showed a lower incidence of post-operation nausea and vomiting.ConclusionTIA can decrease cost of anesthesia and post-operation nursing compared with CIIA.

The Availability of Total Intravenous Anesthesia on Somato-Sensory Evoked Potential during Spinal Surgery / 대한마취과학회지

BACKGROUND: Somatosensory evoked potential (SSEP) has been used to help minimize neurologic morbidity during spinal surgery. But, SSEP is affected by various factors, namely technical errors, anesthetics and physiologic aspects (systemic blood pressure, temperature, blood gas tensions). We experienced 40 cases of spinal surgery done with total intravenous anesthesia under SSEP monitoring. We reviewed these cases with the availability of total intravenous anesthesia during SSEP monitoring. METHODS: Forty patients, ASA class I-II, free of neurologic disease and scheduled for elective spinal surgery were randomly selected for the study. All of the operations were performed under general anesthesia employing the method of total intravenous anesthesia with propofol and fentanyl, and monitored by SSEP. We recorded latency and amplitude of SSEP in the pre-induction, post-induction, during-instrument insertion and post-distraction periods. RESULTS: There were no statistical differences in latencies among pre-induction, post-induction, screw insertion and post-distraction period. The amplitude of the post-induction period was statistically higher than pre-induction period (p<0.05), but there were no differences in other periods. None of cases showed abnormal findings (i.e., delay of latency over 10% or decrease of amplitude over 50%). CONCLUSIONS: SSEP monitoring may be helpful in identifying potentially neurologically threatening surgical maneuvers during spinal surgery. To achieve better outcomes, we should consider the effects of various factors on SSEP. Total intravenous anesthesia may be useful method, which has lifter influence on SSEP monitoring.
