Propofol apnea

Objective: To investigate the effect and safety of transnasal humidified rapid insufflation ventilatory exchange (THRIVE) technique in hysteroscopic diagnostic and therapeutic surgery. Methods: This study was a randomized controlled trial. A total of 100 female patients undergoing hysteroscopy surgery at Beijing Tongren Hospital from September to December 2023 were selected and randomly divided into two groups by the random number table method: the THRIVE group and the mask oxygen group, with 50 patients in each group...

Remimazolam's rapid onset and offset make it an innovative sedative for use during regional anesthesia. However, its respiratory safety profile is not well understood. We compared the continuous infusion of remimazolam with commonly used sedatives, propofol and dexmedetomidine, after regional anesthesia. In this retrospective study, the incidence of apnea (>10 seconds) was assessed in patients who underwent orthopedic surgery under regional anesthesia and received moderate to deep sedation using continuous infusion of remimazolam (group R: 0...

STUDY OBJECTIVE: To assess the efficacy of an ECG-based method called thoracic impedance pneumography to reduce hypoxic events in endoscopy. DESIGN: This was a single center, 1:1 randomized controlled trial. SETTING: The trial was conducted during the placement of percutaneous endoscopic gastrostomy (PEG). PATIENTS: 173 patients who underwent PEG placement were enrolled in the present trial. Indication was oncological in most patients (89%)...

OBJECTIVE: With the recent addition of airflow and respiratory effort channels, our group has observed central and mixed apnea events during drug-induced sleep endoscopy (DISE). We measured the frequency and timing of sentinel central and/or mixed events (SCents), as well as assessed for differences in velum, oropharynx, tongue, and epiglottis (VOTE) classification compared to obstructive events. STUDY DESIGN: Prospective single-cohort study. SETTING: Tertiary Care Academic Medical Center...

INTRODUCTION: Ketamine and propofol are commonly used agents for sedation in the pediatric emergency department (PED). While these medications routinely provide safe sedations, there are side effects providers should be able to recognize and manage. Currently, no pediatric sedation simulations exist in the literature. METHODS: We created two sedation simulation cases for learners, including pediatric emergency medicine (PEM) fellows, working in the PED: case 1, a 12-year-old male with a shoulder dislocation requiring reduction under propofol sedation, and case 2, a forearm fracture requiring reduction under ketamine sedation...

BACKGROUND AND AIMS: Marijuana usage has increased significantly as it has become more readily available and legal, either recreationally or medicinally, in many states. It has been postulated that marijuana usage increases the amount of sedation required for procedures. However, there is minimal data defining this relationship. We aim to establish the relationship between marijuana usage and the amount of sedation used during endoscopy. METHODS: This was a single institution prospective study of patients undergoing outpatient endoscopy (both Monitored Anesthesia Care (MAC) and moderate sedation) at the Oklahoma City Veterans Affairs Medical Center with a total of 976 patients participating...

Children with central sleep apnea may require sedation for procedures, including brain imaging as part of the evaluation of apnea. However, the safety of deep sedation without a protected airway is not known in this patient population. In this case series, we present 3 children with central sleep apnea who were sedated with propofol for brain imaging in a non-operating room setting. All 3 did well with no complications; those with a home oxygen requirement were on oxygen during the procedure but none experienced apnea, desaturation, or respiratory distress...

BACKGROUND AND AIMS: Hypoxemia is one of the most common adverse events during colonoscopy, particularly among patients who are diagnosed with obstructive sleep apnea (OSA) or are overweight. Consequently, the objective of this study was to evaluate the effectiveness of bilevel positive airway pressure (BPAP) ventilation for patients with high-risk hypoxemia during colonoscopy with sedation. METHODS: In this trial, 127 patients who met the eligibility criteria were randomly assigned to the BPAP oxygen group and nasal cannula (NC) group...

PURPOSE: Following demand, we established a patient-controlled propofol-remifentanil sedation service for endoscopy overseen by an anesthesiologist. To assess the effectiveness of the intervention of this service and any complications, we prospectively audited the service. Our primary outcomes of interest were adequacy of sedation and patient satisfaction. Secondary outcomes included any adverse events associated with the sedation. METHODS: Patients were referred for failure of procedure under endoscopist-administered sedation, refusal of procedure without general anesthesia (GA), or planned complex procedure...

We report anesthesia management of sclerotherapy for vascular malformations (VMs) of the upper airway and face of pediatric patients conducted under sedation using a high-flow nasal cannula (HFNC) oxygen delivery system. Sclerotherapy procedures were carried out in six patients (five males, one female; age group: 5-12 years). The patients were sedated with midazolam, fentanyl, ketamine, and graded doses of propofol along with continuous oxygen delivery using HFNC. There were no episodes of oxygen desaturation, tongue fall or obstruction of the airway, interruption of procedure for assisted ventilation, and postoperative nausea and vomiting (PONV)...

BACKGROUND: The number of non-intubated general anesthesia outside the operating room is growing as the increasing demand for comfort treatment. Non-intubated general anesthesia outside the operating room requires rapid onset of anesthesia, smoothness, quick recovery, and few postoperative complications. Traditional anesthetic regimens (propofol alone or propofol and opioids/dezocine/midazolam, etc.) have severe respiratory and circulatory depression and many systemic adverse effects...

General anesthesia is often required in elasmobranch species for medical procedures. A variety of anesthetic drugs have been administered to elasmobranchs with wide variability in efficacy and safety. A retrospective review of 47 anesthetic procedures using IV propofol in eight different elasmobranch species at the Georgia Aquarium from 2010 to 2022 was performed. Cases involving seven sand tiger sharks ( Carcharias taurus ), four largetooth sawfish ( Pristis perotteti ), one longcomb sawfish ( Pristis zijsron ), four blacktip reef sharks ( Carcharhinus melanopterus ), three silvertip sharks ( Carcharhinus albimarginatus), one sandbar shark ( Carcharhinus plumbeus ), five cownose rays ( Rhinoptera bonasus ), and one blotched fantail stingray ( Taeniura meyeni ) were evaluated...

STUDY OBJECTIVE: To determine if a nasal positive airway pressure (nasal CPAP) mask would decrease the number of hypoxemic events in obese and obstructive sleep apnea patients undergoing colonoscopy. DESIGN: Single-center prospective randomized controlled trial. SETTING: Tertiary academic center. PATIENTS: We enrolled 109 patients with diagnosis of obesity and/or obstructive sleep apnea scheduled to undergo colonoscopy under propofol general anesthesia without planned tracheal intubation...

OBJECTIVE: To compare the efficacy and safety of remimazolam with those of propofol for drug-induced sleep endoscopy (DISE) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS). STUDY DESIGN: A prospective, single-center, randomized clinical trial. SETTING: Xiangya Hospital of Central South University. METHODS: Patients with OSAHS receiving DISE were randomly assigned to either the remimazolam or propofol group...

Purpose Intravenous sedation has been well accepted to allow dental restoration in uncooperative children while avoiding aspiration and laryngospasm; however, intravenous anesthetics such as propofol may lead to undesired effects such as respiratory depression and delayed recovery. The use of the bispectral index system (BIS), a monitoring system reflective of the hypnotic state, is con-troversial in the reduction in the risk of respiratory adverse events (RAEs), recovery time, the in-travenous drug dosage, and post-procedural events...

OBJECTIVES: To compare the number of eligible urgent and elective cardiac surgical patients who could be extubated successfully within 6 hours of surgery and who received sugammadex versus those who did not. DESIGN: This retrospective pilot study compared outcomes in cardiac surgical patients undergoing cardiopulmonary bypass between 2018 to 2021 who received sugammadex versus those who did not. SETTING: At a tertiary-care hospital in the Northshore of Chicago...

In a prospective, randomized, experimental non-blinded study, the continuous infusions rates of propofol required to prevent swallowing (P-SR) or pedal withdrawal reflex (P-WR) were evaluated in healthy premedicated dogs. Dogs were randomly assigned to one of two treatments at weekly intervals. Following premedication with a combination of acepromazine and methadone, anesthesia was induced with propofol (4.00 mg kg-1 per min) and was maintained for 90 min. The propofol infusion rate was increased or decreased by 0...

BACKGROUND: Management of children who present with a history of impossible mask ventilation or difficult tracheal intubation is fraught with challenges. Despite this, the "airway stress test" of an inhalational induction is frequently employed risking airway obstruction, breath holding, apnea, and laryngospasm. CASE PRESENTATIONS: We present two cases of children with anticipated difficult airway management. The first child (14-year-old African American boy) had severe mucopolysaccharidosis with a history of failed anesthetic induction and failed airway management...

OBJECTIVES: Pediatric patients undergoing esophagogastroduodenoscopy (EGD) commonly receive procedural sedation for comfort and to facilitate the procedure. EGD with procedural sedation carries the risk of several airway incidents and/or adverse events (AIAE). Topical pharyngeal anesthetics can blunt the airway reflexes and decrease the incidence of laryngospasm but has not been well studied with EGD under procedural sedation. We aimed to study the effect of adding a topical pharyngeal anesthetic (TPA) to propofol-based sedation on the rate of AIAE...
