Background & Objective: One of the most current aggressive methods to access to blood vessels intravenous peripheral catheters that contains excess complications and prevention of it is one of important medical goals. Therefore, this study was done to determining influence dressing with gauze sterile using in complication appearance rate of side effects patients in CCU and having venous catheter. Materials & Methods: This clinical trial accomplished on 64 patient’s hospitalization in CCU and post CCU of Malayer Hospital. 32 of patients in the experimental group (Use of dressing with gaze sterile) and 32 of patients shelled in the control group (Routine) randomly. For data collecting was used checklist and laboratory reports, the method was according to following. Form: In beginning, questionnaire which contained demographic information completed and then venous catheter was enclosed sterility in patient’s hand by one person, after the catheter was replaced, placed the gauze sterile on catheter site for the experimental group (Routine) then every 12 hours considered the place in aspect of phlebitis and infection to 72 hours duration, since phlebitis appearing and or finished 72 hours, the angiocat plastical tip detached from trunck by sterile bisturi and transferred to laboratory tube containing nutritive materials and sent the laboratory during minumm time possible time it was cultured in a culture environment growing 15 colony number on every platelet was considered as positive. Results: 65% of 2 groups are among 61-70 years old 53.1% of both group are illiterate. The majority of both groups (59.4%) had myocardial ischemic heart disease. Catheter situation in the experimental group 53.7% was in the left hand and the control group 63.1% was in the right hand in aspect of type of used drug 44.1% individuals of the 2 groups used 2 drugs heparin and vasodilators. Study’s result about phlebitis with (P<0.05) showed that the gauze sterile dressing has effected in preventing of it’s appearance, therefore statistical fisher test showed that gauze sterile dressing is not effected in preventing of venous catheter’s local infection. Conclusion: The use of the sterile gauze dressing can effect in preventing of phlebitis and colonization.

Background and Objective: Meralgia paresthetica (MP) is due to lateral femoral cutaneous nerve (LFCN) involvement if it is left either unattended miss treated it can be followed by significant disabilities. This study was done to compare the neurolysis and nerve resection in treatment refractory of Meralgia paresthetica. Materials and Methods: This descriptive - comparative study was carried out on 14 patients (7 males and 7 females) afflicted with Meralgia paresthetica and resisted to theraputical regiment in Poorsina hospital in Rasht, North of Iran during 2001-08. The patients were selected non-randomly and neurolysis were gone under either neurolysis or nerve resection surgery with 18-month follow-up. Results: All 5 patients with neurolysis operation were found to have the recurrent symptoms. Non of the patient operated with nerve resection demostrated the clinical manifestation of the recurment sympotms, following 18 month follow-up. The success rate of neurolysis and nerve resection were determined to be 3% and 98.8% respectively. Six women and three men are LFCN-resected a woman and four men treated with neurolysis. The mean age and the disease onset length were 64.6%±9.8 year and 18±11 months, respectively. Conclusion: Nerve resection method is suggested in patients with Meralgia paresthetica resisted to theraputical treatment.

Background and Objective: Previous studies suggest a correlation of central venous pressure (CVP) and peripheral venous pressure (PVP) in different surgeries. CVP is one of essential monitoring during coronary arterial bypass graft (CABG). Canulation of peripheral venous catheter and PVP measurement is easier, whit less complication. This study was done to compare the central venous and peripheral venous pressures in the antecubital region in coronary arterial bypass graft surgery. Materials and Methods: This descriptive analytical study was done on 84 patients with American society of anesthesiology III with CABG surgery in Shafa hospital, Kerman, Iran during 2007. The technique of anesthesia was the same in all patients. CVP and PVP were measured every 20 minutes intervals before, on and after cardio-pulmonary pump. Data were analyzed using STAT-10, ANOVA and linear regression tests. Results: A total of 750 simultaneous measurements of CVP and PVP were recorded in all patients. The mean of CVP before of pump was 6.8±0.9 and the mean of PVP was 8.8±1. The mean difference between CVP and PVP was ±2 mmHg and this difference was significant (P<0.05). The mean of CVP on pump was 3.9±1 and the mean on PVP was 7.6±1. The mean difference of these two changeable was ±3.7 mmHg. This difference was significant (P<0.05). The mean of CVP after of pump was 6.5±1 and the mean of PVP was 8.5±1. The mean difference this two changeable was ±2 mmHg and this difference was significant (P<0.05). Conclusion: PVP and CVP are related with each other on cardio-pulmonary pump even in severe hemodynamic condition. PVP and CVP changes are synchronized and PVP is a helpful clinical alternative for estimation of CVP.

Background and Objective: Repair of peripheral nerve is one of main challenge in surgery and despite improvement in this field less than 50% of cases have functional improvment. This study was done to evaluate the comparison of epineural and peripheral methods in ulnar nerve repair. Method: In this clinical trial study, 28 patients with ulnar nerve injury in distal of forearm were randomly divided equly into epineural and peripheral surgery methods. After 4 months of surgery, the subjects were examined using with EMG, nerve conduction velocity (NCV) and sensorimotor examination on the first dorsal interosos muscle (FDIM) and abductor digiti minim muscle (ADM). Results: The mean of domain nerve activity, latency nerve activity and NCV in affected upper limb and non affected side had significant differences in epineural and peripheral methods (P<0.05). Latency nerve activity and NCV were similar in both methods. The mean of motor unit potential (MUP) was determined in 71% and 64% of patiants in epineural and peripheral methods, respectively. Muscle activity of FDIM was observed in 64% and 57% of patients in epineural and peripheral methods, respectively. Light touch was determined in 35.7% and 28.5% of patients in epineural and peripheral methods, respectively. Pain was reported in 78.5% and 57% of patients in epineural and peripheral methods, respectively. Conclusion: There was no difference between nerve repair by epineurium and prineurium methods using EMG, NCV and motorosensorial examination.
