Randomized Controlled TrialA randomized controlled trial of preinsertion ultrasound guidance for spinal anaesthesia in pregnancy: outcomes among obese and lean parturients : Ultrasound for spinal anesthesia in pregnancy.
The present study was conducted to examine if preinsertion lumbar ultrasound scanning helps with performance of spinal puncture, as a tool for decreasing the number of puncture attempts and spinal procedure time and increasing the success rate. We hypothesized that ultrasound can facilitate neuraxial blockade, particularly in pregnant women with difficult topographic anatomy. ⋯ We found a high level of success in the prepuncture ultrasound-determined insertion point. The ultrasound imaging technique can be a reliable guide to facilitate spinal anesthesia, especially in obese parturients.

Meta AnalysisThe impact of prophylactic intravenous lidocaine on opioid-induced cough: a meta-analysis of randomized controlled trials.
Opioids are commonly used for general anesthesia, but reflex cough can occur after an intravenous injection. We have performed a meta-analysis of randomized controlled trials (RCTs) that evaluated the effectiveness and safety of prophylactic lidocaine administered intravenously (IV) on opioid-induced cough (OIC) during induction in patients undergoing general anesthesia. ⋯ Our meta-analysis establishes the effectiveness of prophylactic lidocaine administered IV for the prevention of OIC during induction. The lowest effective dose of lidocaine on the risk of OIC appeared to be 0.5 mg/kg.

Case ReportsPreoperative morphological analysis by transesophageal echocardiography and predictive value of plasma landiolol concentration during systolic anterior motion mitral valve repair : a report of three cases.
We report three cases with systolic anterior motion (SAM) after mitral valve plasty. Preoperative mitral valve morphology is a risk factor for SAM. ⋯ With the use of 3D transesophageal echocardiography, when mitral valve prolapse was investigated, in all three cases, it was easy to specify lesions. The issue for the future is 3D analysis when SAM is occurring.

Randomized Controlled Trial Comparative StudyComparison of randomized preemptive dexketoprofen trometamol or placebo tablets to prevent withdrawal movement caused by rocuronium injection.
Rocuronium is a non-depolarizing neuromuscular blocking agent which is associated with injection pain and induces withdrawal movement of the injected hand or arm or generalized movements of the body after intravenous injection. The aim of this randomized study was to compare the efficacy of pretreatment with oral dexketoprofen trometamol (Arvelles(®); Group A) with placebo (Group P) without tourniquet to prevent the withdrawal response caused by rocuronium injection. The study cohort comprised 150 American Society of Anaesthesiologists class I-III patients aged 18-75 years who were scheduled to undergo elective surgery with general anesthesia. ⋯ The incidence of score 0 withdrawal movements was higher in Group A (69.9 %) than in Group P (35.4 %), that of score 1 withdrawal movements was similar between groups (Group A 21.9 %; Group B 26.1 %) (p = 0.560) and that of score 2 withdrawal movements was lower in Group A (8.2 %) than in Group P (38.5 %) (p < 0.001). There were no score 3 withdrawal movements in either group (p > 0.05). These results demonstrate that the preemptive administration of dexketoprofen trometamol can attenuate the degree of withdrawal movements caused by the pain of the rocuronium injection.

Improvement of teamwork and safety climate following implementation of the WHO surgical safety checklist at a university hospital in Japan.
With the aim to optimize surgical safety, the World Health Organization (WHO) introduced the Surgical Safety Checklist (SSCL) in 2008. The SSCL has been piloted in many countries worldwide and shown to improve both safety attitudes within surgical teams and patient outcomes. In the study reported here we investigated whether implementation of the SSCL improved the teamwork and safety climate at a single university hospital in Japan. ⋯ A before and after design was used, with the questionnaire administered before and 3 months after SSCL implementation. Our analysis revealed that the mean scores on the SAQ had significantly improved 3 months after implementation of the SSCL compared to those before implementation. This finding implies that effective implementation of the SSCL could improve patient outcomes in Japan, similar to the findings of the WHO pilot study.
