Non-invasive monitoring is coming the full circle, making our patients safer!

Non-invasive monitoring is becoming more accurate, more available and mobile. The clinical advantage that this developing technology provides is that the data may be monitored continuously; relatively unobtrusively, and transmitted directly to the caregiver. The downside of being non-invasive has been the potential loss of accuracy in the data displayed.

American Society for Enhanced Recovery and Perioperative Quality Initiative Joint Consensus Statement on the Role of Neuromonitoring in Perioperative Outcomes: Electroencephalography.

Electroencephalographic (EEG) monitoring to indicate brain state during anesthesia has become widely available. It remains unclear whether EEG-guided anesthesia influences perioperative outcomes. The sixth Perioperative Quality Initiative (POQI-6) brought together an international team of multidisciplinary experts from anesthesiology, biomedical engineering, neurology, and surgery to review the current literature and to develop consensus recommendations on the utility of EEG monitoring during anesthesia.

Anesthesia for Liver Transplantation.

The provision of anesthesia for a liver transplant program requires a dedicated team of anesthesiologists. Liver transplant anesthesiologists must have an understanding of liver physiology and anatomy; the spectrum of clinical disease associated with liver dysfunction; the impact of warm and cold ischemia times, surgical techniques in liver transplantation, and the impact of ischemia-reperfusion syndrome; and optimal practices to protect the liver. The team must provide a 24-hour service, be actively involved in the selection committee process, and stay current with advances in the subspecialty.

International Liver Transplant Society Practice Guidelines: Diagnosis and Management of Hepatopulmonary Syndrome and Portopulmonary Hypertension.

Two distinct pulmonary vascular disorders, hepatopulmonary syndrome (HPS) and portopulmonary hypertension (POPH) may occur as a consequence of hepatic parenchymal or vascular abnormalities. HPS and POPH have major clinical implications for liver transplantation. A European Respiratory Society Task Force on Pulmonary-Hepatic Disorders convened in 2002 to standardize the diagnosis and guide management of these disorders.

Sedation levels during propofol administration for outpatient colonoscopies.

The levels of sedation required for patients to comfortably undergo colonoscopy with propofol were examined. One hundred patients undergoing colonoscopy with propofol were enrolled. In addition to standard-of-care monitoring, sedation level was monitored with the Patient State Index (PSI) obtained from a brain function monitor, transcutaneous carbon dioxide (tcpCO2) was monitored with the TCM TOSCA monitor, and end-tidal carbon dioxide was monitored via nasal cannula.

Dexmedetomidine infusion for analgesia up to 48 hours after lung surgery performed by lateral thoracotomy.

Patients undergoing a lateral thoracotomy for pulmonary resection have moderate to severe pain postoperatively that is often treated with opioids. Opioid side effects such as respiratory depression can be devastating in patients with already compromised respiratory function. This prospective double-blinded clinical trial examined the analgesic effects and safety of a dexmedetomidine infusion for postthoracotomy patients when administered on a telemetry nursing floor, 24 to 48 hours after surgery, to determine if the drug's known early opioid-sparing properties were maintained.

Incidence and severity of respiratory insufficiency detected by transcutaneous carbon dioxide monitoring after cardiac surgery and intensive care unit discharge.

Patients undergoing coronary artery bypass surgery and/or heart valve surgery using a median sternotomy approach coupled with the use of cardiopulmonary bypass often experience pulmonary complications in the postoperative period. These patients are initially monitored in an intensive care unit (ICU) but after discharge from this unit to the ward they may still have compromised pulmonary function. This dysfunction may progress to significant respiratory failure that will cause the patient to return to the ICU.

Chylopericardium following orthotopic lung transplantation.

Chylopericardium is an uncommon condition, reported to occur following routine cardiac surgery, orthotopic heart transplantation, cardiac trauma, intrathoracic tumors, or infection. It has not, to date, been reported following uncomplicated orthotopic lung transplantation. This article describes chylopericardium following bilateral orthotopic lung transplantation.

Evaluating and monitoring sedation, arousal, and agitation in the ICU.

Optimal management of patient comfort and sedative drug therapy for intensive care unit (ICU) patients includes establishing a goal of therapy-often defined by a desired level of consciousness, with titration of medications to achieve this target. An assessment of the level of consciousness is best performed using a simple tool, such as a sedation scale that relies on observation of the patient to assign a level of conscious that ranges from alert to unarousable. Many sedation scales incorporate observation of the patient's response to stimulation, which typically escalates from simply calling the patient's name to physical stimulation.

The accuracy, precision and reliability of measuring ventilatory rate and detecting ventilatory pause by rainbow acoustic monitoring and capnometry.

Background: Current methods for monitoring ventilatory rate have limitations including poor accuracy and precision and low patient tolerance. In this study, we evaluated a new acoustic ventilatory rate monitoring technology for accuracy, precision, reliability, and the ability to detect pauses in ventilation, relative to capnometry and a reference method in postsurgical patients.

Methods: Adult patients presenting to the postanesthesia care unit were connected to a Pulse CO-Oximeter with acoustic monitoring technology (Rad-87, version 7804, Masimo, Irvine, CA) through an adhesive bioacoustic sensor (RAS-125, rev C) applied to the neck.

Clinical practice guidelines for the management of pain, agitation, and delirium in adult patients in the intensive care unit.

Objective: To revise the "Clinical Practice Guidelines for the Sustained Use of Sedatives and Analgesics in the Critically Ill Adult" published in Critical Care Medicine in 2002.

Methods: The American College of Critical Care Medicine assembled a 20-person, multidisciplinary, multi-institutional task force with expertise in guideline development, pain, agitation and sedation, delirium management, and associated outcomes in adult critically ill patients. The task force, divided into four subcommittees, collaborated over 6 yr in person, via teleconferences, and via electronic communication.

Evaluation of the SEDline to improve the safety and efficiency of conscious sedation.

Brain function monitors have improved safety and efficiency in general anesthesia; however, they have not been adequately tested for guiding conscious sedation for periodontal surgical procedures. This study evaluated the patient state index (PSI) obtained from the SEDline monitor (Sedline Inc., San Diego, CA) to determine its capacity to improve the safety and efficiency of intravenous conscious sedation during outpatient periodontal surgery.

Evaluating and monitoring analgesia and sedation in the intensive care unit.

Management of analgesia and sedation in the intensive care unit requires evaluation and monitoring of key parameters in order to detect and quantify pain and agitation, and to quantify sedation. The routine use of subjective scales for pain, agitation, and sedation promotes more effective management, including patient-focused titration of medications to specific end-points. The need for frequent measurement reflects the dynamic nature of pain, agitation, and sedation, which change constantly in critically ill patients.

Rapid sequence induction and intubation with 1 mg/kg rocuronium bromide in cesarean section, comparison with suxamethonium.

Objective: To demonstrate that Rocuronium Bromide can be used for rapid sequence induction in emergency conditions.

Methods: Our study was performed between December 2005 and May 2006 in Jordan University Hospital, Jordan. We studied the efficacy and intubating conditions after administrating of Rocuronium Bromide 1 mg/kg at 60 second in group of 60 pregnant women undergoing elective or emergency cesarean section and compared the results with those obtained after giving Suxamethonium 1 mg/kg at 60 seconds in a group of patients similar to the Rocuronium group.

Use of dexmedetomidine versus general anesthesia for endovascular repair of abdominal aortic aneurysms.

While abdominal aortic aneurysms have traditionally been treated with a major open surgical procedure, minimally invasive endovascular techniques are much less traumatic, with significantly less strain on the heart and vital organs. A sedation technique using dexmedetomidine, an alpha 2-adrenoreceptor agonist, was developed for this procedure. We retrospectively reviewed records of 231 patients who underwent endovascular repair of abdominal aortic aneurysms at the Baylor Jack and Jane Hamilton Heart and Vascular Hospital from January 1, 2001, until September 30, 2005.
