Clinical trials

This randomized controlled trial will evaluate different epidural lidocaine-bupivacaine mixtures in patients undergoing lower limb surgery at a tertiary care hospital in Karachi, Pakistan. Ninety-six participants will be randomly assigned to one of three study groups receiving different combinations of lidocaine and bupivacaine for epidural anesthesia. The purpose of this study is to determine which anesthetic mixture provides the most effective anesthesia for lower limb surgery. The study will compare the speed of onset and duration of anesthesia, as well as the effects of the anesthetic mixtures on cardiovascular stability during surgery. The results of this study may help identify an epidural anesthetic regimen that provides optimal surgical conditions, effective pain control, and stable hemodynamic parameters for patients undergoing lower limb procedures.

The goal of this clinical trial is to find out whether height-based dosing of spinal anaesthesia provides better hemodynamic stability and anesthetic outcome than conventional fixed dosing in elderly patients undergoing lower limb orthopaedic surgery.The main questions this study aims to answer are: 1. Does height-based spinal anaesthetic dosing reduce the risk of hypotension and bradycardia during surgery as compared to conventional fixed dosing? 2. Does it improve anaesthetic outcomes, such as the onset and duration of sensory and motor block?

The goal of this clinical trial is to learn if povidone-iodine foam dressing is better in achieving complete reepithelialization of donor site wounds after harvest of split-thickness skin graft as paraffin mesh gauze. The main questions it aims to answer are: Does povidone-iodine foam dressing promotes complete reepithelialization earlier in comparison? Which type of dressing will require fewer replacements? Which type of dressing material is associated with less pain? Non-probability consecutive sampling method will be used and participants divided in two groups. Donor site wounds after split-thickness skin graft harvest will be dressed using two different dressing materials. Participants will be followed until complete epithelialization with change of dressing on follow-ups if required. Complete epithelialization is usually achieved within two weeks.

The goal of this clinical trial is to learn if intravenous dexamethasone is effective for prevention of post spinal hypotension in geriatric population undergoing orthopedic surgeries. The main question aim to answer is: Does intravenous dexamethasone in participants undergoing orthopedic procedures of lower limb under spinal anesthesia prevents post spinal hypotension? Researchers are comparing two groups of participants * Participants in (Dexamethasone Group) Group D are receiving intravenous dexamethasone 8mg preoperatively * Participants in (Placebo Group) Group P are receiving placebo preoperatively.

The goal of this trial is to compare efficacy of xylometazoline nasal drops and adrenaline nasal pack in participants undergoing elective oromaxillofacial surgeries. The main question aim to answer is xylometazoline nasal drops better than adrenaline nasal packing in terms of nasal bleeding during nasotracheal intubation. Researchers are comparing 2 groups of participants. Participants in group Xylometazoline are receiving 0.1% xylometaxoline nasal drops. Participants in group Adrenaline are receiving adrenaline nasal packing.

The goal of this clinical trial is to know which type of laryngoscope is better for Double Lumen Tube (DLT) insertion, in participants undergoing elective thoracic surgeries. The main question aim to answer is Is C-MAC blade D video laryngoscope better than Macintosh laryngoscope for DLT insertion in term of time taking for intubation and hemodynamic changes to laryngoscopy? Researchers are comparing two groups of participants * Participants in Group A are receiving intubation from C-MAC blade D video laryngoscope. * Participants in Group B are receiving intubations from Macintosh laryngoscope.
