Positive end-expiratory pressure-induced increase in external jugular venous pressure does not predict fluid responsiveness in laparoscopic prostatectomy.
Dynamic change in central venous pressure (CVP) was associated with fluid responsiveness. External jugular venous pressure (EJVP) may reliably estimate CVP and have the advantages of being less invasive. We investigated whether increase in EJVP induced by positive end-expiratory pressure (PEEP) could be a reliable predictor of fluid responsiveness in patients undergoing robot-assisted laparoscopic prostatectomy (RALP). ⋯ Our study results suggested that SVV and increase in EJVP after applying PEEP were not accurate predictors of fluid responsiveness during RALP. Further studies are required to find an adequate preload index in robot-assisted urologic surgery with steep Trendelenburg position.

Observational StudyPostoperative renal function in parturients with severe preeclampsia who underwent cesarean delivery: a retrospective observational study.
Although postoperative renal dysfunction is relatively rare after cesarean delivery, preeclampsia is considered as the high-risk population. On the other hand, hydroxyethyl starch (HES) administration for preventing maternal hypotension induced by spinal anesthesia for cesarean delivery is a common practice. However, the effect of HES administration during cesarean delivery on postoperative kidney function in parturients with severe preeclampsia is not well investigated. ⋯ The amounts of HES administration were 859 ± 206 mL. There was significant reduction in serum creatinine, from 0.70 ± 0.29 mg/dL preoperatively to 0.62 ± 0.17 mg/dL in 3-7 days after the cesarean. Only one patient had postoperatively elevated serum creatinine up to clinically significant level (from 0.64 mg/dL to 1.35 mg/kg).

Clinical TrialThe Pringle maneuver reduces the infusion rate of rocuronium required to maintain surgical muscle relaxation during hepatectomy.
We investigated the continuous infusion rates of rocuronium necessary to obtain the surgical muscle relaxation before, during, and after the Pringle maneuver on patients who underwent hepatectomy. ⋯ In case of continuous administration of rocuronium during surgery performing the Pringle maneuver, it was considered necessary to regulate the administration of rocuronium using muscle relaxant monitoring in order to deal with the decrease in muscle relaxant requirement by the Pringle maneuver.

Observational StudyThe evaluation of the effect of venous diameter measurement by ultrasonography on pain and withdrawal response.
Rocuronium and propofol are used in the induction of anesthesia give discomfort to the patients. We aimed to investigate the relationship between venous diameter measured using ultrasonography, and pain and withdrawal movements after propofol and rocuronium applied with intravenous (IV). ⋯ In this study, we found a reduction in the incidence and severity of pain and withdrawal movements in intravenous propofol and rocuronium administration through peripheral venous vessels of large diameter. We believe that the clinical drug injection through vessels with large venous diameter with the help of USG may be a non-invasive, simple, and reliable method to reduce pain and withdrawal movements in propofol and rocuronium injections.

Impact of age on postoperative complication rates among elderly patients with hip fracture: a retrospective matched study.
This study was performed to assess the impact of age of ≥ 90 years on predicting postoperative complications. We retrospectively identified all patients aged ≥ 65 years who underwent surgical repair of hip fractures over a 4.5-year period in our hospital. In total, 261 patients were identified (mean age, 86.2 ± 6.8 years). ⋯ After propensity adjustment for these characteristics, postoperative complication rates in the oldest-old group remained significantly higher than those in the matched control group (odds ratio (OR) 2.76, 95% confidence interval (95% CI) 1.24-6.49; P = 0.011). Major complications also developed more frequently in the oldest-old group than control group (OR 9.78, 95% CI 1.31-4.36; P = 0.018). Anesthesiologists and surgeons should pay attention to potential complications following hip fracture surgery for patients aged ≥ 90 years regardless of American Society of Anesthesiologists class or social dependency.
