Abstract
Background & Aim: Access to peripheral veins in more than 80% of hospitalized patients is necessary. This skill is more difficult in the patients with overweight. The study was conducted to determine the effect of local heating on the success rate of venipuncture in the patients with overweight.
Methods & Materials: An unblinded, randomized clinical trial (IRCT2017020832133N1) was done on 70 patients with overweight, hospitalized in the internal department of Imam Reza hospital in Mashhad in 2016. Subjects were randomly allocated to the two groups of experimental and control. For the experimental group, the 39.5 degree (Celsius) local dry heat was applied at the venipuncture site, 10 minutes before venipuncture. The control group had venipuncture in a similar condition but without local heating. In the two groups, the rate of visibility and palpability of peripheral veins was measured by the Lenhardt scale, the required time for venipuncture was determined by chronometer and the number of venipuncture attempt was measured by counting. Data were analyzed by descriptive statistics, independent t-test and Chi-square using the SPSS software version 16.
Results: For the intervention and control groups, the average number of venipuncture attempt were respectively 1.0±0.1 and 1.3±0.5 times, duration of venipuncture were 89.7±26.3 and 120±38.9 seconds and the rate of visibility and palpability of peripheral veins were 2.9±0.7 and 2.3±0.5, and all were statistically significant (P<0.05).
Conclusion: The use of local heating for the overweight patients can increase the visibility and palpability of peripheral veins and decrease the duration of venipuncture and venipuncture attempts.

Abstract
Background & Aim: Brain injury is one of the most common traumas and the most important cause of death in traumatic events. Ventilated patients are susceptible to pressure ulcers caused by endotracheal tube fixation (ETF). The aim of the present study is to compare three methods of ETF (band, adhesive and holder) on the incidence of pressure ulcers in patients with head injury.
Methods & Materials: This randomized clinical trial was performed in a hospital in Mashhad in 2017. A total of 108 hospitalized patients with head trauma were included in the study by convenience sampling. The patients were randomly divided into three groups of ETF using holder, band and adhesive. In three groups, the incidence of pressure ulcers caused by fixation method was assessed at 6, 12, 18, and 24 hours after the intervention. The grade of ulcer was measured by pressure grading scale (EPUAP/NPUAP). The data were analyzed using the SPSS software version 16.
Results: The incidence of pressure ulcers at 6, 12, 18, and 24 hours after the intervention was significantly different in the three groups (P<0.05). At six and 12 hours after the intervention, the three groups had a grade one ulcer. However, after 18 hours, 10% in the adhesive group and band group and 24 hours after the intervention, 25% in the band group and 12.1% in the adhesive group had a grade 2 pressure ulcer, but this amount was 0% in the holder group.
Conclusion: Use of holder rather than adhesive and band for ETF in mechanically ventilated patients causes less pressure ulcers.
