Active clinical trials for "Emergencies"

Hypotension during anesthesia is associated with serious organ failure and death. The most critical period for intraoperative hypotension is the postinduction period during which, one-third of intraoperative hypotension occurs. Post-induction hypotension has many contributing factors; however, it is closely related to anesthetic drugs. Therefore, manipulation of induction agents makes post-induction hypotension likely preventable. Emergency laparotomy is a critical category of surgery whose patients are usually hemodynamically compromised and prone to post-induction hypotension; furthermore, these patients are usually at high risk of aspiration of gastric contents and require rapid-sequence induction of anesthesia and optimum intubating conditions. Thus, induction of anesthesia for emergency laparotomy requires meticulous balance between achievement of adequate hypnosis and maintenance of stable blood pressure. Propofol is the commonest hypnotic agent worldwide. However, it is usually associated with hypotension especially in compromised patients. Ketamine produces dissociative anesthesia and sympathetic stimulation which provides more stable hemodynamic profile; however, ketamine is not widely used as a routine hypnotic because it produces psychomimetic effects such as delirium and emergence agitation. Nevertheless, ketamine still has a role in induction of anesthesia in patients with shock and during procedural sedation. Ketamine is also used as analgesic adjuvant during general anesthesia. Propofol/ketamine admixture (ketofol) was introduced in anesthetic practice aiming to compensate the side effects of the two drugs and to provide, consequently, the desired balance between adequate hypnosis and hemodynamic stability. Ketofol is currently used with a diversity in the ratio between the two drugs which ranges between 1:1 and 1:10 between ketamine and propofol. Despite its frequent use in sedation and complete anesthesia, most of the available literature for comparisons of different ketofol mixtures was restricted to procedural sedation whose results are not applicable in induction of anesthesia due to the different desirable level of hypnosis and recovery. Therefore, the best combination of the two components of ketofol for induction of anesthesia is unknown

Post-operative wound complications in abdominal surgery have a major impact on patient outcomes and the real impact of Closed incision negative pressure therapy (CINVt) is not clear in the literature moreover concerning its potential economic benefits The hypothesis of this study is that CINPt has the potential to reduce Surgical Site Infections. Secondly the investigators aim to study the economic impact of CINPt used after abdominal emergency laparotomies.

The objective of this study is to evaluate the efficacy of and patient satisfaction with the use of intranasal tranexamic acid (TXA) for anterior nosebleeds in the emergency department (ED).

To evaluate the efficiency of ultrasound with IV contrast and compare this with the Computed Tomography in acute flank pain patient at Emergency Department.

Severe inequities in HIV pre-exposure prophylaxis (PrEP) access and use in communities hardest hit by the HIV epidemic persist, further exacerbating ongoing racial/ethnic and socioeconomic disparities in HIV incidence. In these same communities, many patients at risk for HIV seek care for sexually transmitted infections (STIs) in Emergency Departments (EDs), but the structure of traditional ED care is poorly suited to address HIV prevention or provide PrEP. To advance the Prevent objective of the Ending the HIV Epidemic (EHE) initiative, ED2PrEP will leverage an implementation science approach to rigorously test two innovative strategies for increasing PrEP uptake among patients seeking STI care in EDs in one of the 48 EHE-identified geographic hotspots.

The aim of this study is to investigate the effect of early, supplementary parenteral nutrition following emergency laparotomy. Currently, parenteral nutrition is used in postoperative patients if or when oral or enteral nutrition is not feasible. However, little data exists on the optimal timing of parenteral nutrition. Oral and enteral nutrition is encouraged. Participants will randomized on the second postoperative day if their calorie intake (oral + enteral) is below 30% of the calculated requirement. Patients will be randomized to early (postoperative day 2) or postponed (postoperative day 5) start of parenteral nutrition. The combined oral + enteral + parenteral calorie target is 70-80% of the calculated requirement. Participants in the postponed group will be re-assessed on postoperative day 5, and if their calorie intake is less than 50% parenteral nutrition will be administered. The intervention will continue until oral + enteral intake is at least 70% of the calculated requirement or the participant is at his/her habitual intake.

Low back pain accounts for billions of dollars in health care expenditures. Most cases of back pain do not have a clear cause. Thus, low back pain management methods usually rely on targeting people' pain and discomfort. Painkillers, including opioids, are usually prescribed in the emergency departments for people with low back pain. But, like all medications, painkillers can have side effects, and some of those can be serious. There are also serious concerns about the overuse of painkillers. Thus, newer pain management methods are needed to reduce the use of painkillers in people with low back pain. Lumbar braces are one of the underutilized low back pain management methods in the emergency departments. Like crutches for leg and ankle injuries, they can minimise movements of the spine. This may decrease people pain and improve their function. This may also reduce the use of painkillers. In support of this approach, two recent studies conducted in a primary-care setting observed a reduction in the use of painkillers in people with low back pain who wore lumbar braces. The investigators are conducting this study to determine if wearing a lumbar brace for 4 weeks following emergency department presentation will reduce people's pain and discomfort and increase spine function. This may decrease the use of painkiller and future use of healthcare resources. This research study may also assist emergency-department staff with offering new recommendations to improve the quality of clinical decisions.

The main aim of this study is to determine whether Serratus Anterior Plane (SAP) blockade provides improved pain relief after rib fractures compared to epidural administration of local anaesthetic. The investigators aim to show that SAP catheters (SAPC) can be placed in more situations and are less operator-dependent then thoracic epidural anaesthesia (TEA). This reduces the waiting time required to achieve satisfactory analgesia in the patient. Optimal analgesia allows early respiratory physiotherapy and reduction in the complications of multiple rib fractures. Pain from rib fractures is severe. The sensory nerves of the thoracic wall lie in the SAP and a single ultrasound-guided injection of local anaesthetic spreads widely and provides useful post-injury analgesia for several hours. If a catheter is left in the SAP, the nerve blockade can be maintained for several days. Rib Fracture pain is traditionally treated with oral/ intravenous analgesics or TEA. Opiate analgesia via patient controlled analgesia (PCA) can work very well but it is associated with excessive sedation, constipation, nausea and vomiting. Continuous TEA is generally regarded as the gold standard but it demands monitoring by adequately trained ward staff and is commonly associated with high failure rates and increased risk of complications. SAPC has also been used when TEA and PCA were not desirable. The primary outcome will be the amount of morphine analgesia required by the patient. Secondary outcomes will be pain scores (at rest and on movement), the side effects of morphine, complications of TEA/ SAPC, respiratory function changes and a quality of recovery assessment. The control group will have an epidural block and catheter placed. The treatment group will have SAP blocks and catheters placed under ultrasound guidance. Both blocks will be tested to ensure good pain relief. To avoid potential confounding effects, oral painkillers will adhere strictly to the study protocol.

This randomized control trial aims to compare the efficacy of triclosan-coated barbed suture (TCB) versus conventional non-barbed polydioxanone (PDS) suture in the closure of the abdominal fascia after emergency exploratory laparotomy. The study addresses the common complications of incisional surgical site infections (SSI) and fascial dehiscence (FD) following emergency exploratory laparotomy. The primary objective is to assess the effectiveness of triclosan-coated barbed suture and conventional non-barbed suture in reducing the rates of incisional SSI and FD within 30 days postoperatively. The study population comprises adult patients undergoing emergent laparotomy for traumatic injuries or acute intraabdominal pathology. This prospective, single-blinded randomized control trial will be conducted at Los Angeles General Medical Center. Patients will be randomized to receive either triclosan-coated barbed suture or conventional non-barbed suture for abdominal fascial closure, with a standard closure technique employed. Patients will be followed up for 30 days postoperatively to monitor surgical site infections, fascial dehiscence, and other outcomes. Statistical analysis will be conducted to compare outcomes between the study arms, assessing the efficacy of triclosan-coated barbed suture in reducing the incidence of SSI and FD, along with secondary outcomes.

Nurses Taking on Readiness Measures (N-TORM) is an innovative nurse-driven household emergency preparedness intervention modeled after an existing community intervention provided by emergency management personnel. The proposed pilot studies will test the Korean translation of the Household Emergency Preparedness Instrument (K-HEPI) and describe the implementation and effectiveness of N-TORM in a community setting. The aims of this instrument translation study and cluster randomized controlled trial are to (a) field and pilot test the K-HEPI in order to perform psychometric testing on the instrument and generate reliability and validity data, (b) increase the accessibility of N-TORM to vulnerable populations, (c) evaluate the effectiveness of N-TORM to increase household emergency preparedness knowledge and behavior, (d) implement N-TORM in a community located in an area at increased risk for disasters, measuring consistency of delivery, time, and cost of N-TORM, and (e) describe the factors most necessary to maintain and expand N-TORM.
