The aim of this PhD thesis was to provide a continuous method to monitor myocardial function during cardiac surgery with the superior sensitivity of ultrasonic technique and the continuity of electrocardiographic (ECG) monitoring. ⋯ The provided ultrasound system could give continuous real-time monitoring of myocardial function, and detect myocardial dysfunction with superior sensitivity than ECG or hemodynamic monitoring. This could be used for improved monitoring of myocardial function during cardiac surgery.

Review Meta AnalysisDexmedetomidine for preventing sevoflurane-related emergence agitation in children: a meta-analysis of randomized controlled trials.
Emergence agitation (EA) is a common problem after sevoflurane anesthesia in children. Prophylactic dexmedetomidine has been directed at this issue; however, the efficacy remains controversial. We therefore conducted a meta-analysis of randomized controlled trials (RCTs) to evaluate the effectiveness of dexmedetomidine on the incidence of sevoflurane-related EA. ⋯ Dexmedetomidine reduced the incidence of sevofurane-related EA (pooled RR = 0.351; 95% CI: 0.275-0.449; P = 0.965; heterogeneity test, I(2) = 0.0%), and it also resulted in a lower incidence of severe EA (pooled RR = 0.119; 95% CI: 0.033-0.422; P = 0.962; heterogeneity test, I(2) = 0.0%). All subgroup analyses for potential sources of heterogeneity showed a lower incidence of sevoflurane-related EA after dexmedetomidine administration. This meta-analysis demonstrated that dexemedetomidine was effective in reducing the incidence of sevoflurane-induced EA in children as compared with placebo.

Randomized Controlled Trial Clinical TrialContinuous positive airway pressure/pressure support pre-oxygenation of morbidly obese patients.
Morbidly obese patients are more prone to desaturation of arterial blood during apnea with induction of anesthesia than are non-obese. This study aimed to assess the effect of low-pressure continuous positive airway pressure (CPAP) with pressure support ventilation (PSV) during pre-oxygenation on partial oxygen pressure in arterial blood (PaO2 ) immediately after tracheal intubation (post-intubation PaO2). ⋯ In morbidly obese patients, low-pressure CPAP combined with low-pressure PSV during pre-oxygenation resulted in better oxygenation, compared with neutral-pressure breathing, and prevented desaturation episodes.
