Intravenous (IV) catheterization is one of the common painful procedures in children. This study aimed to investigate the effect of cold and warm vibration on pain caused by IV catheterization in 3- to 6-year-old children using a buzzy device.

A randomized clinical trial was carried out in 108 children in Mashhad Akbar Pediatric Hospital selected via random blocking. They were divided into three groups to receive warm vibration, cold vibration, or vibration only (control group). In this study, a musical vibrating device in a form of bee with either a warm or cold pack was attached for 5 min at approximately 5-10 cm above the intravenous continuous infusion (IVCI) site. In last minute, vibration was applied, then, IV catheterization was done. The Wong-Baker FACES Pain Rating Scale (WBS) was used to rate pain severity. Data were analyzed in SPSS V19 at a significance level of 95%.

Before the intervention, there were no significant differences in mean pain score between the three groups (P>0.05). Pain score was significantly different during the procedure (P<0.05). Significant difference was seen in pain score between the two intervention groups (P<0.05). The pain score was found to be significantly different between the intervention group that received cold vibration and the control group (P<0.05), but, the score was not significantly different between the group with warm vibration and the control group (P>0.05).

Both cold and warm vibrations could reduce the pain caused by injection, but cold vibration showed greater effect on reducing pain. Therefore, cold or warm vibrating devices are suggested in management of aggressive painful procedures in children.

Intravenous catheter insertion in hospitalized children is common, invasive, painful and fearful procedure which can change physiological indicators. This study aimed to assess the effect of inhalation aromatherapy with Lavender essence on physiological indicators of intravenous catheter insertion in hospitalized preschool children.
A single-blind clinical trial was conducted using convenience sampling on 60 hospitalized preschool children at the pediatric ward in Beast hospital of Hamadan city in 2015. In the aromatherapy group, 30 children inhaled 5 drops of 2% Lavender essence and in the control group, 30 children inhaled 5 drops of distilled water as a placebo for 20 minutes before entering the venipuncture room. Physiological indicators were measured in 30 minutes before intravenous catheter insertion, immediately, 5 and 10 minutes after intravenous catheter insertion. Data were analyzed using SPSS (version 16) and Chi-squire, independent t, repeated measurement and multiple comparison tests.
There were significant differences between mean of heart rate (P= 0.001), SpO2 (P= 0.003) and respiratory rate (P= 0.001) at before, immediately, 5 and 10 minutes after intravenous catheter insertion in aromatherapy and control group.
Inhalation aromatherapy with Lavender essence reduced physiological changes of intravenous catheter insertion in hospitalized preschool children. It can be used as a simple, inexpensive and safe complementary treatment in pediatric wards.

A main purpose of clinical training in nursing education is mastery of clinical skills، which are learnt through repetition. So there is a relation between frequency of skill performance and clinical competency. In this study we used learning curve to set standards for required performance times of two main nursing skills: intramuscular injection and intravenous catheter insertion.

This time series study was conducted on 57 junior nursing students who were selected through a convenience sampling method at Mashhad nursing school during 2011. Competency score of each student for each skill performance episode was evaluated by Competency Evaluation Checklist (CEV) and recorded on learning curve till reaching a plateau. CEV was confirmed by computing content validity index and intra-rater reliability coefficients (r=. 91).

Mean competency score of IM injection was 62. 4%±21. 5 (out of 100) in first time which increased by 95. 1±5. 9 in tenth episode. The calculated value for IV catheter insertion was 36. 9±10. 3 in first time and 94. 1±4. 3 in the thirteenth. Learning curve was reached a plateau after 7 performances for intramuscular skill and 8 performances for intravenous catheter insertion skill. The number of practice episodes in IM injection and IV Catheter insertion required for acquiring a rate of 75% in competency، by 75% of students were 6 and 7 times، respectively.

It seems that at least 7 to 8 performances of IM injection and IV catheter insertion are considered essential to attain students’ mastery. Also designing and application of a clinical logbook is useful for documenting skills performance by nursing students.
