Transesophageal echocardiography (TEE), which is commonly used for monitoring and diagnostic imaging during cardiovascular surgery, was originally developed by a strong desire to know what was taking place in the heart in the dark ages of cardiac surgery. The author was fortunate to be present in the midst of the development of TEE and have an opportunity to take a close look at the history of this innovation. Furthermore, the author believes that the history of TEE contains important lessons and tips for solving the problems we presently face in clinical practice...

PURPOSE: Emergence delirium (ED) is common in children after sevoflurane anesthesia and should be prevented for patient safety. A prospective, double-blind, randomized, controlled study was performed to compare the efficacy of minimal dosage of midazolam versus dexmedetomidine to prevent ED in children undergoing tonsillectomy. METHODS: Seventy children aged 24 months to 12 years were allocated to receive midazolam (0.03 mg/kg) or dexmedetomidine (0.3 µg/kg) 5 min before the end of surgery...

INTRODUCTION: The gold standard for measuring the partial pressure of carbon dioxide remains arterial blood gas (ABG) analysis. For patients with cystic fibrosis undergoing general anesthesia or polysomnography studies, continuous non-invasive carbon dioxide monitoring may be required. The current study compares end-tidal (ETCO2 ), transcutaneous (TCCO2 ), and capillary blood gas carbon dioxide (Cap-CO2 ) monitoring with the partial pressure of carbon dioxide (PaCO2 ) from an ABG in patients with cystic fibrosis...

Microaspiration of bacteriologically contaminated oropharyngeal secretions alongside the cuff of an endotracheal tube (ETT) is a key mechanism for development of ventilator-associated pneumonia. We have constructed a prototype double-cuffed ETT equipped with a supplemental port in-between the cuffs through which continuous positive airway pressure (CPAP) is delivered. Pressure in the intercuff space propels secretions upwards and produces 100% tracheal sealing in an in vitro model. We conducted a 24 h study to investigate the sealing effect of this ETT in 12 critically ill mechanically ventilated patients...

A right aortic arch with an aberrant left subclavian artery and a Kommerell's diverticulum represents a rare anatomic variant carrying the risk of dissection or rupture. Resection of the diverticulum and re-implantation of the left subclavian artery during childhood have been recommended. Because of the risk of cerebral blood flow reduction during the aberrant subclavian artery re-implantation to the common carotid artery, monitoring and prompt measures to curb blood flow reduction are required. A 5-month-old boy was scheduled to undergo resection surgery...

BACKGROUND: The issue whether anaesthesia has an impact on the prognosis of carcinoma has been widely discussed and remains debated. Ropivacaine has been widely used in perioperative period as a long acting local anesthetic. An early event during recurrence or metastasis of carcinoma is the adhesion of circulating tumour cells (CTCs) to endothelial cells (ECs) through binding adhesion molecules that are up-regulated on inflamed endothelium during the perioperative period or other periods...

Beta-adrenergic blockers (β-blockers) are clearly indicated for the long-term treatment of patients with systolic heart failure and post-acute myocardial infarction. Early small-scale studies reported their potential benefits for perioperative use; subsequent randomized controlled trials, however, failed to reproduce earlier findings. Furthermore, their role in reducing major postoperative cardiac events following noncardiac and cardiac surgery remains controversial. This case-based review presents an overview of contemporary literature on perioperative β-blocker use with a focus on data available since 2008 when the PreOperative ISchemic Evaluation (POISE) trial was published...

There is little evidence of gastric excretion after ingestion of solids. We examined gastric emptying times after ingesting normal breakfast in healthy adult volunteer using ultrasonography. Eight adult volunteers fasted for 8 h, and we examined the gastric antral area in the right lateral decubitus position using ultrasonography. Sixteen adult volunteers ingested normal breakfast. We evaluated the gastric antral area in the same manner at two consecutive time points before lunch. Gastric volume was calculated by using an approximation formula based on the antral area...

Postoperative motor dysfunction can develop after spinal surgery, neurosurgery and aortic surgery, in which there is a risk of injury of motor pathway. In order to prevent such devastating complication, intraoperative monitoring of motor evoked potentials (MEP) has been conducted. However, to prevent postoperative motor dysfunction, proper understanding of MEP monitoring and proper anesthetic managements are required. Especially, a variety of anesthetics and neuromuscular blocking agent are known to attenuate MEP responses...

Transnasal humidified rapid insufflation ventilatory exchange (THRIVE) is a recent technique that delivers warm humidified high flow oxygen to patients, allowing for prolonged apneic oxygenation. A review of current literature was performed to determine the use of THRIVE in apneic patients undergoing surgery in a shared airway setting. An initial free hand search was done to identify keywords followed by a systematic search of major databases with no date or language restrictions. Inclusion criteria include all apneic patients who receive THRIVE for any operative procedure...

PURPOSE: Hemodynamic management during low central venous pressure (L-CVP)-assisted hepatectomy involves fluid restriction during resection and fluid resuscitation after resection. Recently, high stroke volume variation (SVV) has been reported as an alternative to L-CVP for reducing blood loss during a hepatectomy. The current study evaluated the impact of a newly implemented SVV-based goal-directed therapy (GDT) protocol on blood loss during hepatectomy. METHODS: We conducted a before-after comparative study, which included L-CVP-assisted hepatectomy cases (control group) and GDT-assisted hepatectomy cases (intervention group)...
