Effect of total intravenous versus inhalation anesthesia on long-term oncological outcomes in patients undergoing curative resection for early-stage non-small cell lung cancer: a retrospective cohort study / 대한마취과학회지

Background@#Propofol-based total intravenous anesthesia (TIVA) improves long-term outcomes after cancer surgery compared with inhalation anesthesia. However, its effect on patients undergoing non-small cell lung cancer (NSCLC) surgery remains unclear. We aimed to compare the oncological outcomes of TIVA and inhalation anesthesia after curative resection of early-stage NSCLC. @*Methods@#We analyzed the medical records of patients diagnosed with stage I or II NSCLC who underwent curative resection at a tertiary university hospital between January 2010 and December 2017. The primary outcomes were recurrence-free survival (RFS) and overall survival (OS) according to anesthesia type. @*Results@#We included 1,508 patients with stage I/II NSCLC. The patients were divided into the TIVA (n = 980) and Inhalation (n = 528) groups. The two groups were well-balanced in terms of baseline clinical characteristics. The TIVA group demonstrated significantly improved RFS (7.7 years, 95% CI [7.37, 8.02]) compared with the Inhalation group (6.8 years, 95% CI [6.30, 7.22], P = 0.003). Similarly, TIVA was superior to inhalation agents with respect to OS (median OS; 8.4 years, 95% CI [8.08, 8.69] vs. 7.3 years, 95% CI [6.81, 7.71]; P < 0.001). Multivariable Cox regression analysis revealed that TIVA was an independent prognostic factor related to recurrence (hazard ratio [HR]: 1.24, 95% CI [1.04, 1.47], P = 0.014) and OS (HR: 1.39, 95% CI [1.12, 1.72], P = 0.002). @*Conclusions@#Propofol-based TIVA was associated with better RFS and OS than inhalation anesthesia in patients with stage I/II NSCLC who underwent curative resection.

Medications or food before anesthesia to note taking

Decisions about stopping or continuing medications perioperatively should be based on withdrawal potential, the potential for disease progression if therapy is interrupted, and the potential for drug interactions with anesthesia. In general, most medications are tolerated well through surgery and do not interfere with anesthetic administration. Therefore, most drugs should be continued through the morning of surgery. However, some medications are known to influence surgical risk or surgical decisions (e.g., antiplatelet agents, anticoagulants, some hormonal therapies, and herbal remedies), so it is important to obtain a complete medication list from the patient and to advise adjusting doses or discontinuing certain potentially complicating medications in advance of surgery. This article reviews general recommendations for perioperative management of a number of common medication classes.

Persistent perioperative tachycardia and hypertension diagnosed as thyroid storm induced by a hydatidiform mole: a case report / 대한마취과학회지

Thyroid storm is a critical complication of molar pregnancy. However, early diagnosis of it is difficult because it is a rare complication and usually presents nonspecific findings. In this case report, we present a woman with molar pregnancy who had persistent tachycardia and hypertension. She was diagnosed initially with preeclampsia and sepsis as complications of molar pregnancy. During dilation and curettage under general anesthesia with sevoflurane and remifentanil, tachycardia and hypertension remained even with continuous infusion of labetalol. The patient was subsequently diagnosed with thyroid storm associated with molar pregnancy. She was restored to a clinically euthyroid state 1 day after the operation, and her thyroid function test and beta-hCG values were normal 3 months later. The anesthesiologists should bear in mind the possibility of thyroid storm in patients with molar pregnancies who show persistent tachycardia and hypertension.
