12 Clinical Trials for Various Conditions
After cardiac surgery patients are transported from the operating room (OR) to the intensive care unit (ICU) while intubated. Two principal methods of oxygenation and ventilation are used: (1) a transport ventilator or (2) a Mapleson Bag-Mask hand ventilating circuit. The choice of method is largely determined by the preference of the the anesthesiologist who is transporting the patient. The investigators postulate that the choice of either method might alter respiratory and hemodynamic parameters felt to be important for the immediate management of post-cardiac surgery patients. The investigators will prospectively record end-tidal carbon dioxide (ETCO2) (primary end-point) and change in minute volume, heart rate (HR), Blood pressure (BP), pulmonary artery (PA) pressures and cardiac output during transportation and upon arrival in the ICU. All of these variables are measured routinely but are not recorded. The investigators will compare patients transported with a ventilator to patients transported with a Mapleson circuit.
The purpose of this pilot study is to identify the optimal way to ventilate patients during abdominal surgery in order to reduce the amount of post-operative pulmonary complications in patients at moderate and high-risk for them.
The goal of this study is to learn more about voice and airway problems that patients experience during and after the time patients have an oral endotracheal tube in patients' airway to help patients breathe while receiving mechanical ventilation in an intensive care unit (ICU).
An early intervention for swallowing disorders (i.e., dysphagia) during endotracheal intubation may improve patient outcomes. The investigators propose treatment sessions targeting sensorimotor integration, strength, and range of motion during oral endotracheal intubation with mechanical ventilation to reduce or prevent dysphagia and aspiration (food or liquids entering the airway), establish a solid foundation in understanding reasons for swallowing impairment after extubation from mechanical ventilation and learn new methods to reduce or prevent these problems.
The purpose of this study is to determine the efficacy of TTIP-first ventilation and to compare the efficacy of TTIP first ventilation with the current practice of mask-first ventilation
Previous clinical trials in adults with acute respiratory distress syndrome (ARDS) have demonstrated that ventilator management choices can improve Intensive Care Unit (ICU) mortality and shorten time on mechanical ventilation. This study seeks to scale an established Clinical Decision Support (CDS) tool to facilitate dissemination and implementation of evidence-based research in mechanical ventilation of infants and children with pediatric ARDS (PARDS). This will be accomplished by using CDS tools developed and deployed in Children's Hospital Los Angeles (CHLA) which are based on the best available pediatric evidence, and are currently being used in an NHLBI funded single center randomized controlled trial (NCT03266016, PI: Khemani). Without CDS, there is significant variability in ventilator management of PARDS patients both between and within Pediatric ICUs (PICUs), but clinicians are willing to accept CDS recommendations. The CDS tool will be deployed in multiple PICUs, targeting enrollment of up to 180 children with PARDS. Study hypotheses: 1. The CDS tool in will be implementable in nearly all participating sites 2. There will be \> 80% compliance with CDS recommendations and 3. The investigators can implement automatic data capture and entry in many of the ICUs Once feasibility of this CDS tool is demonstrated, a multi-center validation study will be designed, which seeks to determine whether the CDS can result in a significant reduction in length of mechanical ventilation (LMV).
This study is a Phase II controlled clinical trial that will obtain comprehensive, serial assessments of respiratory muscle strength and architecture to understand the evolution of ventilator-induced respiratory muscle weakness in critically ill children, and test whether a novel computer-based approach (Real-time Effort Driven ventilator management (REDvent)) can preserve respiratory muscle strength and reduce time on MV. REDvent offers systematic recommendations to reduce controlled ventilation during the acute phase of MV, and uses real-time measures from esophageal manometry to adjust supported ventilator pressures such that patient effort of breathing remains in a normal range during the ventilator weaning phase. This phase II clinical trial is expected to enroll 276 children with pulmonary parenchymal disease, anticipated to be ventilated \> 48 hrs. Patients will be randomized to REDvent-acute vs. usual care for the acute phase of MV (interval from intubation to first spontaneous breathing trial (SBT)). Patients in either group who fail their first Spontaneous Breathing Trial (SBT), will also be randomized to REDvent-weaning vs. usual care for the weaning phase of MV (interval from first SBT to passing SBT). The primary clinical outcome is length of weaning (time from first SBT until successful passage of an SBT or extubation (whichever comes first)). Mechanistic outcomes surround multi-modal serial measures of respiratory muscle capacity (PiMax), load (resistance, compliance), effort (esophageal manometry), and architecture (ultrasound) throughout the course of MV. Upon completion, this study will provide important information on the pathogenesis and timing of respiratory muscle weakness during MV in children and whether this weakness can be mitigated by promoting more normal patient effort during MV via the use of REDvent. This will form the basis for a larger, Phase III multi-center study, powered for key clinical outcomes such as 28-day Ventilator Free Days.
The proposed A/Z modification of a supraglottic airway (SGA) incorporates an opening in the SGA body that enables access to the endotracheal tube (ETT) through the body of the SGA without the need of using an exchange catheter, thus enabling an ETT to move in the body of the SGA and convert a supraglottic to endotracheal ventilation. In its original form an adaptor made from same material currently used in the endotracheal tubes can make ventilation through the proposed airway device possible in exactly the same manner of a conventional SGA currently used. This adapter also known as the R-piece can be replaced with an ETT. The modification also allows placement of SGA over an existing ETT to convert and endotracheal (ET) to supraglottic (SG) mode of ventilation without the need to use an exchange catheter.
The objective of this study is to gather initial information about the testing of a novel manual communication system for mechanically ventilated Intensive Care Unit (ICU) subjects. This phase of the study is not hypotheses based; the goal is to gather data about which potential form factors and interaction modes of the proposed communication system are most intuitive for subjects and caregivers.
The objective of this study is to gather initial information about the testing of a novel manual communication system - which is currently called MOCS, for Manually Operated Communicated System - for mechanically ventilated Intensive Care Unit (ICU) subjects. This study is not hypothesis based; the goal is to gather data about which interaction modes and teaching approaches of MOCS are most intuitive for subjects and caregivers.
The purpose of this study is to use CBT strategies in assisting patients hospitalized in intensive care units in ventilation wean through a case series of 2 patients.
To evaluate whether ketamine is a safe sedative-analgesic agent to be used in an intensive care unit (ICU) setting as compared to traditionally used agents such as propofol, opioids, and midazolam
