Performing Percutaneous Dilational Tracheostomy without using Fiberoptic Bronchoscope.

Background: Percutaneous tracheostomy is an elective method that is increasingly being taken up in the intensive care unit alongside the patient's bed. In many centers, bronchoscopy is used, but the necessity of using bronchoscopy in percutaneous tracheostomy has not yet been determined. Discontinuing use of bronchoscopy can potentially reduce the cost and increase the efficiency of percutaneous tracheostomy.

Effect of Intervenous Magnesium Sulfate on Decreasing Opioid Requirement after Surgery of the Lower Limb Fracture by Spinal Anesthesia.

Background: Magnesium is the calcium natural physiological antagonist; it also antagonizes N-Methyl-D-aspartate receptors, therefore, providing antinociceptive properties. The reason for effective role of treatment with magnesium on decreasing opioid usage, less dissatisfaction, and good sleep quality is proposed theoretically yet. This study aimed to evaluate the effect of magnesium sulfate on decreasing opioids requirement after surgery of the lower limbs fracture by spinal anesthesia.

The postoperative analgesic effect of morphine and paracetamol in the patients undergoing laparotomy, using PCA method.

Objective: postoperative pain increases the activity of the sympathetic system, causes hypermetabolic conditions, retains salt and water, increases glucose, fatty acid lactate and oxygen consumption, weakens the immunity system which delays wound healing. Our object was comparison of the analgesic effect of morphine and paracetamol in the patients undergoing laparotomy, using PCA method.

Method: Seventy patients who had undergone laparotomy were studied using double blind randomized clinical trial (35 patients received morphine and 35 paracetamol) in the Shahid Rajaee Center and Velayat Hospital (Qazvin, Iran).

Determining the effect of intraperitoneal pethidine on postoperative pain.

The main problem in the postoperative period is pain relief. Adequate postoperative analgesia not only leads to patient's comfort but also decreases morbidity, nursing care and time of hospitalization. Determination of the effect of intraperitoneal pethidine on postoperative pain in women scheduled for elective tubal ligation was undertaken.
