• Propofol-Based Deep Sedation for Percutaneous Radiofrequency Ablation in Sick Elderly Patients with Hepatocellular Carcinoma in a Developing Country - MedCrave online The aim of this study was to evaluate and compare the clinical efficacy of propofol-based deep sedation (PBDS) for percutaneous radiofrequency ablation (RFA) in sick (American Society of Anesthesiologists [ASA] physical status III-IV) and nonsick (ASA physical status I-II) elderly patients in a teaching hospital in Thailand. We undertook a retrospective review of the sedation service records of elderly patients who underwent RFA procedures from 2010 to 2012. Patients were classified into two groups according to ASA physical status. In group A, patients had ASA I-II, while in group B, patients had ASA III-IV. Primary outcome variable was the successful completion of procedure. Secondary outcome variables were sedation-related complications during and immediately after procedure. There were 113 elderly patients who underwent RFA procedures by using PBDS during the study period. Of these, 69 patients were in group A and 44 patients were in group B. There were no significant differences in age, weight, duration of sedation, and mean dose of propofol, fentanyl, and midazolam between the two groups. All procedures in both groups were successfully completed. Overall and cardiorespiratory-related complications in both groups were not significantly different. All sedation-related complications were easily treated, with no adverse sequelae. PBDS for percutaneous RFA in sick elderly patients by trained anesthetic personnel with appropriate monitoring was safe and effective. The clinical efficacy of this technique in sick elderly patients was not different or worse than in nonsick elderly patients. Serious complications were rare.

• Adverse Event Rate of Unsedated Esophagogastroduodenoscopy: a Comparison Between Healthy Adults and Cirrhotic Patients - MedCrave online This study was aimed to evaluate and compare the adverse event rate of pharyngeal anesthesia when the topical lidocaine is used as a single agent for unsedated esophagogastroduodenoscopy (UEGD) between healthy adults and cirrhotic patients. Retrospectively analyzed the patients on whom UEGD procedures had been performed during the period of June, 2008 to December, 2009 in Siriraj Hospital. Patients were categorized into two groups. Group A was the healthy adults. Group B was the cirrhotic patients. The primary outcome variable was the adverse event rate. Secondary outcome variables were anesthesia and procedure-related adverse events, and mortality rate. There were 1,398 patients who underwent UEGD procedure during the study period. After matching age, gender, weight, height and duration of procedure, there were 131 patients in group A and 129 patients in group B. All pharyngeal anesthesia was given by residents or anesthetic nurses directly supervised by staff anesthesiologist in the endoscopy room. There were no significant differences in age, gender, weight, height, duration of procedure, and overall adverse event rate between the two groups. Hypertension in group B was significantly greater than in group A. However, tachycardia and hypertension in group B was significantly lower than in group A. All adverse events were transient, easily treated, with no adverse sequelae. UEGD in healthy adults and cirrhotic patients was safe and effective. Although, overall adverse event rate was relatively high, however, all adverse events in both groups were comparable, mild degree, transient and easily treated. No serious adverse events were observed in these two groups.

• Intravenous sedation techniques in gastrointestinal endoscopy | Amornyotin | Journal of Gastroenterology and Hepatology Research 1,594 Gastrointestinal endoscopic (GIE) procedure has become an essential modality for evaluation and management of gastrointestinal tract abnormalities. The safe sedation of patients for this procedure requires a combination of properly trained physicians and appropriate facilities. Moreover, proper selection and preparation of patients, suitable sedative technique, and application of drugs is essential. Irrespective of regimen used, the safe administration of sedative drugs requires an awareness of the individual needs of the patients.

• Registered nurse-administered sedation for gastrointestinal endoscopic procedure Most endoscopic patients require some forms of sedation and/or anesthesia. The goals of this sedation are to guard the patient’s safety, minimize physical discomfort, to control behavior and to diminish psychological responses. Generally, moderate sedation for these procedures has been offered by the non-anesthesiologist by using benzodiazepines and/or opioids. Anesthesiologists and non-anesthesiologist personnel will need to work together for these challenges and for safety of the patients.

• Ketofol: A Combination of Ketamine and Propofol - MedCrave online Ketofol is a combination of ketamine and propofol. To date, there is significant interest in ketofol as an agent for procedural sedation and analgesia. The combination of propofol and ketamine has several benefits in the terms of hemodynamic stability, absence of respiratory depression, post-operative analgesia and recovery. This combination can be mixed in the same syringe or administered independently in the two separate syringes. It can be administered as a bolus or as a continuous infusion for longer procedures. Ketamine-propofol combinations in the different ratios have been studied before. The optimal mixture and dosing of ketamine and propofol has yet to be determined. This short review will highlight recent clinical supports the therapeutic utility of the combination of ketamine and Propofol.

• Monitoring for depth of anesthesia: a review | Somchai | Journal of Biomedical Graphics and Computing Monitoring depth of anesthesia is a newer advance in the monitoring of anesthesia. Accurate assessment of the depth of anesthesia contributes to tailoring drug administration to the individual patient. Its increasing use may help to prevent awareness or excessive anesthetic depth and to improve the patients’ outcomes. Awareness experiences frighten the patients and can leave a lifetime of residual emotional and psychological problems. To date, no monitoring system has been found to measure the depth of anesthesia reliably for all patients and all anesthetic agents. In this review, the author critically analyzes the use of a number of the depth of anesthesia monitors including the traditional techniques and the modern techniques.
