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. Therefore, in this study, we performed a percutaneous dilatational tracheostomy without using fiberoptic bronchoscopy. MATERIALS AND METHODS: This study was performed as a descriptive epidemiological survey among 70 patients in Shahid Rajaei Hospital of Qazvin in 2015 and 2016. The results were assessed in the patients. RESULTS: In this study, pneumothorax, trauma, major and minor bleeding, cuff leak and change to surgical procedures as well as accidental extubation were not seen. However, subcutaneous emphysema, mal-position and hypoxia each were seen in one patient (1.4%). CONCLUSION: Totally the results demonstrated that percutaneous dilatation tracheostomy without fiberoptic bronchoscopic guidance is useful and safe.

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. METHODS: A total of 60 patients aged from 45 to 75 years with the lower limb fractures (femur and hip) candidate for surgery by spinal anesthesia. In a randomized double-blind method, patients were divided into two groups as Magnesium Group (M) and Control Group (C). Group M received a bolus of 5 mg/kg magnesium sulfate plus (250 CC) normal saline and Group C received (250 CC) normal saline in the same condition. RESULTS: Pain score and the physical dissatisfaction were reduced at 12, 24, and 48 h after surgery in Group M as compared with Group C (P = 0.000). Total opioid requirement at the end of 48 h and at the first 24 h after surgery were reduced in Group M as compared with Group C (P = 0.001). The endurance of spinal block was increased in Group M as compared with Group C (P = 0.000). CONCLUSIONS: A low dose of magnesium sulfate reduced the pain score, opioid requirement, and physical dissatisfaction while increased endurance of spinal block.

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). People using opioids, painkillers and sedatives regularly and in large doses and patients with a history of lung or liver problems did not participate in this project. The parameters of the severity of pain and nausea (VAS), hemodynamic changes (BP and HR), pruritus, arterial oxygen desaturation and patient satisfaction (VAS) of both groups were measured by a third party (trained colleague). The data was analyzed using SPSS 16 statistical software then descriptive results were extracted and ultimately the groups were compared using the following statistical tests: student's T-test, chi 2 and Fisher's exact test (P<0.05). FINDINGS: The mean age of the participants was 45±12.5 years. Women constituted 24.3% of the patients and men 75.7%. The average pain severity for morphine and paracetamol groups (VAS) was 5.3±2.2and 6.37±1.7 after2 hours and reached 1.91±1.3 and 2.49±1.3 after 8 hours (after the operation) respectively. There was a significant difference between the groups after 2 and 4 hours in terms of pain severity (after 2 hours P=0.007 and after 4 hours P=0.047). However there was no significant difference between the average pain severity of the studied groups (after 6 hours P=0.4 and 8 hours P=0.08). After 8 hours, the average nausea severity was the minimum in both groups being 1.71±1.6 and 1.43±1.1 in morphine and paracetamol groups respectively. Nausea severity was higher after 2 hours in paracetamol group. In morphine group, it was higher after 4, 6 and 8 hours. Difference between the groups was not significant. The average satisfaction level (VAS) for morphine and paracetamol groups reached from 5.29±2.3 and 4.2±2.4 after 2 hours, to 7.94±1.8 and 7.69±2.1 after 8 hours (after the operation), respectively. The average satisfaction level of patients was higher in morphine group in 2,4,6 and 8 hours and except for, after 4 hours (P=0.01), the satisfaction difference between both groups was not significant in other hours (P=0.06 after 2 hours, P=0.6 after 6 hours and P=0.5 after 8 hours) CONCLUSION: Morphine seems to be more effective at 2 and 4 hours, but after 4 hours they have similar effects, the satisfaction difference between both groups was not significant in the patients.

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. In a double blind clinical trial study of 60 women, ASA I, 25-45 years old, were enrolled for elective tubal ligation in Kosar hospital in Qazvin, IRAN. Patients were randomly divided in two equal groups (30 each).One group received pethidine intraperitoneally and the other group received equal amount of placebo in the same region. The intensity of postoperative pain was evaluated by visual analogue scale (VAS) for about 8 hours. Incidence of nausea was also evaluated. Data was transformed to SPSS software. Then data analysis was performed by U-test. There was no significant statistical difference with regard to age, weight, and time of operation between the two groups. The mean score of pain was significantly lower in intraperitoneal pethidine group than placebo group but the incidence of nausea in the intraperitoneal pethidine group was more than in placebo group (P < 0.05). Thus, intraperitoneal pethidine decreases postoperative pain but increases postoperative nausea.
