Clinical trials

Intraoperative hypotension is commonly treated with fluid administration; however, excessive fluid therapy may contribute to postoperative pulmonary complications. This randomized double-blind controlled trial evaluates whether proactive administration of fixed low-dose norepinephrine reduces intraoperative crystalloid administration while maintaining hemodynamic stability in high-risk patients undergoing laparoscopic abdominal surgery. One hundred and thirty patients will be randomized to receive either norepinephrine infusion (0.03 µg/kg/min) or placebo from induction until skin closure within a protocolized hemodynamic strategy guided by mean arterial pressure and pulse pressure variation.

Stress urinary incontinence (SUI) is a common pelvic floor disorder among women, especially those with a history of childbirth, aging, or pelvic surgery. Stress urinary incontinence is defined as the complaint of involuntary leakage on effort or exertion, or on sneezing or coughing. The condition significantly affects quality of life, emotional well-being, and daily functioning.

Achieving effective root canal disinfection while minimizing postoperative pain is a critical goal in endodontic therapy. Advanced irrigation protocols, such as ultrasonic activation, laser activation, negative pressure irrigation (PulpSucker device), and mechanical activation (Easy Clean device), have shown promise in enhancing bacterial reduction within the root canal system. However, their impact on postoperative pain has not been fully explored. This randomized controlled clinical trial aims to compare bacterial reduction and postoperative pain levels in infected root canals using four different irrigation protocols. The study will use metagenomic analysis to evaluate changes in bacterial community composition and the Visual Analogue Scale (VAS) to assess patient-reported pain levels at multiple time points postoperatively.

Group II (control group) will have stainless steel screws/pins placed bucco-palatally to maintain the elevated membrane and stabilize the formed blood clot. Platelet rich fibrin (PRF) will be placed at the site of elevated membrane in both groups.

Pre-eclampsia, more than being proteinuric gestational hypertension alone, is a state of exaggerated systemic inflammation and remains a leading direct cause of maternal morbidity and mortality worldwide.1 Standardization of antenatal and postnatal assessment and surveillance of pre-eclampsia with protocols that recognize the systemic inflammatory model of preeclampsia have been associated with reduced maternal morbidity.

This study investigates the role of respiratory variation in the internal jugular vein as a tool for intraoperative fluid management during abdominal surgeries under general anesthesia. The purpose of this clinical trial is to reduce postoperative complications and improve patient outcomes through proper intraoperative fluid management. The main question it aims to answer is: Can intraoperative fluid management guided by the respiratory variation of the internal jugular vein during abdominal surgeries reduce postoperative complications? Research Hypothesis (Alternative Hypothesis): We hypothesize that fluid management guided by the respiratory variation of the internal jugular vein during abdominal surgeries can reduce postoperative complications. The patients will be divided into two groups and randomized to receive either intraoperative fluid therapy guided by the respiratory variation of the internal jugular vein or standard fluid therapy. Postoperative complications, length of hospital stay, total amount of fluid administered intraoperatively, use of vasopressors in both groups, and incidence of hypotensive episodes will be recorded.

Cataract surgery in elderly patients with controlled hypertension carries a risk of hemodynamic instability, particularly fluctuations in mean arterial blood pressure (MAP). Dexmedetomidine, a selective α2-adrenergic agonist, offers hemodynamic stabilization and sedation when administered intranasally and provides a simple and non-invasive premedication option. This study evaluates the effects of intranasal dexmedetomidine on perioperative mean arterial blood pressure in patients undergoing cataract surgeries. Research Question: Does intranasal dexmedetomidine premedication control blood pressure in elderly hypertensive patients undergoing cataract surgery? Research Hypothesis: Intranasal dexmedetomidine significantly reduces MAP and improves secondary outcomes compared to placebo. Primary Objective: To evaluate the efficacy of intranasal Dexmedetomidine as a premedication to control hypertension in elderly patients scheduled for cataract surgery. Secondary Objectives: 1. To assess surgery cancellation rates. 2. To evaluate satisfaction levels among patients, anesthesiologists, and surgeons using the Modified Observer's assessment of alertness/sedation scale (MOAA/S). 3- To evaluate the effect of intranasal dexmedetomidine on HR multiple readings starting from preoperative hold area till 2 hours postoperatively. This randomized, double-blinded clinical trial will include 126 elderly hypertensive patients (≥65 years) undergoing cataract surgery under local anesthesia. Inclusion Criteria will consist of patients aged ≥65 years, ASA II or III, stage 2 hypertension as per ACC / AHA guidelines (SBP\>140 and DBP\> 90 mmHg), undergoing elective cataract surgery under local anesthesia. Exclusion Criteria will include allergy or contraindication to dexmedetomidine, significant baseline bradycardia (\<50 bpm) or arrhythmia, use of sedative or anxiolytic medications, history of severe hepatic, renal, or cerebrovascular disease. Participants will be randomly assigned to receive either intranasal dexmedetomidine (1 mcg/kg ideal body weight) or a placebo (normal saline) 30 minutes before surgery. MAP, HR, and SpO₂ will be recorded at multiple perioperative intervals, and surgical cancellation rates, satisfaction levels will be noted, surgical duration, and hospital stay will be documented.
