NCT ID: NCT05216523 Completed - COVID-19 Clinical Trials

"Barotrauma in Admitted Covid-19 Cases - A Single Center Retrospective Study"

Start date: June 24, 2021
Study type: Observational

A retrospective study is planned to find out the incidence and association type of respiratory support with barotrauma in Covid-19 cases admitted in Sultan Qaboos University Hospital. As widely known, Covid-19 affects the respiratory system primarily and is the main cause of admission to hospital. Depending upon the severity, different levels of respiratory support are offered to the patients. Normally patients with viral/bacterial respiratory diseases have a low incidence of barotrauma. Since this disease is new and it has been observed that a significant number of covid-19 patients develop barotrauma, hence it is deemed worthwhile to investigate the matter. All the patients admitted to the ward, high dependency unit, and intensive care unit will be scanned and those who developed barotrauma (pneumothorax, surgical emphysema, pneumo-pericardium, and pneumo-mediastinum) will be studied in detail and analyzed. This review is expected to highlight the problem and etiology and we might be able to suggest a management strategy to deal with this problem.

NCT ID: NCT04989270 Completed - Clinical trials for Obstetric Anaesthesia With Cardiac Complications

A Superior Anesthetic Technique for the Cesarean Section From a Hemodynamic Perspective.

Start date: July 7, 2020
Study type: Observational

Cesarean section operations are increasing in rates worldwide. A proper anesthetic technique is required to maintain the safety of both the mother and the fetus. This study examines the adverse hemodynamic effects associated with general and regional anesthesia and proposes a superior technique from the hemodynamic perspective. A retrospective cohort study with a five-year study period was conducted on patients who underwent cesarean section with general anesthesia (GA) and regional anesthesia (RA) after obtaining ethical committee approval. Data (hypotension, bradycardia, and blood loss) was collected from hospital information system records of the patients who underwent cesarean section from January 2015 to December 2019. The significance of the variables was determined using the Chi-square test. A total of 2500 patients were studied. 1379 patients underwent cesarean section with RA meanwhile 1121 patients with GA.

NCT ID: NCT04955782 Recruiting - Infertility, Male Clinical Trials

Abstinence Period and Semen Quality

Start date: September 16, 2021
Study type: Observational [Patient Registry]

Does period of abstinence impact progressive motility in oligoasthenoteratozoospermic (OATS) males? In the evaluation of male fertility, semen analysis is an important investigation. An abstinence between 2 and 7 days before a diagnostic semen analysis has been recommended by WHO (WHO 2010 guidelines), for the sake of standardization. The European Society of Human Reproduction and Embryology advises 3-4 days of abstinence before a semen analysis. The exact impact of abstinence period on sperm quality is a little complex and difficult to interpret. This study, 250 men with low sperm counts, motility and morphology will be recruited. The results will be analyzed to ascertain the impact of shorter abstinence period on semen quality

Start date: December 13, 2021
Phase: Phase 3
Study type: Interventional

This Phase 3 study will assess the safety and efficacy of a single dose of inclacumab, a P-selectin inhibitor, for a vaso-occlusive crisis (VOC) after an index VOC in participants with sickle cell disease (SCD). Participants will be randomized to receive either inclacumab or placebo.

NCT ID: NCT04715243 Terminated - Clinical trials for Acute Respiratory Distress Syndrome Caused by COVID-19

Comparison of High Flow Nasal Cannula (HFNC), Face-mask Non-Invasive Ventilation (NIV) & Helmet NIV in COVID-19 ARDS Patients

Start date: February 2, 2021
Phase: N/A
Study type: Interventional

Objective: To determine whether NIV delivered through helmet interface reduces intubation rate among patients with COVID-19 ARDS compared to face-mask NIV and HFNC. Design, setting & participants: Two-center randomized clinical trial of 360 patients with mild to moderate ARDS and confirmed COVID-19 requiring non-invasive ventilation between August 2020 to January 2021. The patients with respiratory rate (RR) more than 30/min or oxygen saturation (SpO2) less than 90% or PaO2/FiO2 ratio less than 300 despite standard oxygen therapy by face mask (<15 L/min) who present to Royal hospital or Sultan Qaboos University Hospital (SQUH) emergency department, medical wards or intensive care unit (ICU). Intervention: Patients will be randomly assigned (block randomization) to either face-mask NIV, HFNC or Helmet NIV. The helmet is a transparent hood that covers the entire head of the patient and has a rubber collar neck seal. Main outcome and measures: The primary outcome is the rate of endotracheal intubation at 28-days. Secondary outcomes include hospital mortality at 28 and 90 days, NIV free days, invasive ventilator free days and hospital length of stay. Expected results: We assume the failure rate of Helmet NIV to be 30%, failure rate of HFNC to be 40% and failure rate of face-mask NIV to be 50%. A sample size of 360 patients (120/group) will achieve a power of 0.90 at a significance level of 0.05. To account for 10% dropout rate, the total sample required is 396 subjects(132/group).

NCT ID: NCT04680208 Completed - Clinical trials for Postoperative Complications

Study of Direct Admission of Postoperative Patients to ICU

Start date: July 1, 2019
Study type: Observational

Background: This study assessed perioperative factors associated with planned and unplanned postoperative ICU admission and evaluated the outcome of the two groups. There are limited researches evaluating these factors. Hence, it is important to do an audit that assesses the perioperative factors to help creating a criteria for postoperative ICU admissions. Materials and methods: This retrospective study evaluated medical records of 68 patients above 18 years between January'2016- December'2018 that were admitted to ICU postoperatively in Sultan Qaboos University hospital in Oman. Both planned and unplanned admissions were assessed who underwent elective as well as emergency surgeries. Neurologic and cardiothoracic surgeries were excluded. Data collected included patient's demographics, social status like smoking, ASA physical status (American Society of Anesthesiologists), associated comorbidities, other perioperative factors and investigations, surgical and anesthesia details were recorded. The primary outcome studied was reasons of admission for planned versus unplanned postoperative ICU admissions. The secondary outcomes included mortality outcome and length of stay in ICU.

NCT ID: NCT04441762 Completed - Acute Renal Colic Clinical Trials

Atomized Intranasal Vs Intravenous Ketorolac in Acute Renal Colic Pain Management.

Start date: December 30, 2020
Phase: Phase 2/Phase 3
Study type: Interventional

Introduction: Pain is a common reason for individuals to seek health care, especially emergency care. Ketorolac has numerous advantages over other pain medications, especially the opioids. The intranasal administration of ketorolac has been shown to be safe and effective in the treatment of postoperative pain following major abdominal surgery and post dental surgery, but there have been no studies evaluating the use of intranasal ketorolac for the treatment of acute renal colic pain in the emergency department. Methods: This is a double blinded randomized controlled trial. two hundred renal colic patients presented to the emergency department will be randomized to intervention (30 mg intranasal ketorolac) and (30mg intravenous ketorolac) case groups. Their pain before and after receiving ketorolac will be measured by visual Analog Scale (VAS pain score). Patient, attending physician and administering nurse will be blinded throughout the study. The analgesic effects will be assessed by several measures including pain relief, pain intensity difference, global pain evaluation, global assessment of analgesia, and the summed pain intensity difference. The safety will be assessed by documentation of adverse events, vital signs, and clinical assessment before and after drug administration. Aim: The aim of this study is to compare analgesic effects of intranasal Ketorolac tromethamine versus intravenous Ketorolac tromethamine in adult patients with moderate to severe renal colic. Primary Objective: Analgesic effects of Intranasal Ketorolac on the visual analog scale (VAS). Secondary Objectives: Adverse Events, the need of rescue pain medications, time to discharge and recurrent visit within 24 hours. Patient Population: Adults (from age 18 to 64 years) who presents to emergency department (ED) at Sultan Qaboos University Hospital with moderate to severe acute flank pain suggestive of renal colic (visual analog scale 7 or more). Intervention: Single dose of intranasal ketorolac 30mg. Clinical measurement: Visual Analog Scale will be assessed at 0, 30 and 60 minutes after intervention. Number and dosage of rescue medication, any reported events by patient or attending physician will be documented. Outcome: Decrease in pain measures by VAS pain score after intranasal ketorolac is given, tolerability and safety evaluation.
