Brief summary

This study was conducted to determine the effect of mechanical vibration and ShotBlocker methods on pain level, crying time and procedure time during heel prick blood collection in healthy term infants.

Detailed description

Heel prick blood collection, which is one of the painful medical procedures, is one of the diagnostic methods used in newborns and is a more painful procedure compared to other blood collection procedures. Prevention of pain in newborns should be the primary goal of all healthcare personnel working with newborns, both because it is an ethical obligation and because repeated painful exposures have the potential to cause harmful consequences. Nonpharmacologic methods used for the control of acute pain associated with medical procedures are easy to use, have no side effects, are inexpensive and time-saving. Mechanical vibration and ShotBlocker application are among the non-pharmacologic methods frequently used in the management of pain associated with heel prick procedure in term infants. Previous studies have shown that parent-related methods (kangaroo care, mother/father hug, breastfeeding, etc.) are commonly used for pain management of the newborn during heel prick. In this respect, it is important to determine the effectiveness of mechanical vibration and ShotBlocker methods that can be used independently of the parent, especially in intensive care settings where access to the parent is not always possible.

Interventions

DEVICEShotBlocker

The protruding surface of the ShotBlocker was placed on the heel lance procedure site. While applying pressure on the skin through the ShotBlocker, the nurse performed heel lancing with the needle through the opening in the center of the ShotBlocker. During the 10-second waiting phase, the ShotBlocker was kept at the procedure site with the same pressure. Then ShotBlocker was removed from the skin and routine capillary blood collection procedure was performed.

The vibration device was placed on the infant's left extremity in the mid/lateral region just below the knee where the sural nerve passes. The device was secured to the extremity with a gauze bandage. The vibration device was operated for 30 seconds with reference to previous studies. While the vibration continued, the nurse punctured the heel with a needle. Then, the vibration device continued to work in the waiting phase for 10 seconds. The vibration device was removed from the baby's extremity and routine capillary blood collection procedure was performed.

Masking description

Using the block randomization technique, participants were divided into three groups. A web-based randomization list generation tool was used to assign participants to groups. Control and intervention groups were coded as A, B and C using the sealed envelope method. Randomization information was withheld from the researcher involved in data collection until data was collected. The researcher determines which group each baby is in. The researcher found out during the painful procedure. (investigator blinding). Within the scope of the research, parents knew which group the baby was in. However, due to the nature of the sample group, the babies were blind. To avoid statistical bias, study groups were coded as A, B and C; statistical blinding was performed (statistician blinding).

Intervention model description

In the study, participants were assigned to groups by block randomization. Type of delivery (vaginal and cesarean section), gender (male and female) and birth weight (2500-3000 g, 3001-3500 g, 3501 and above) variables were used for block randomization. Blocks were repeated three times in each group and 36 participants were assigned to each. A randomization list with 2 X 2 X 3 X 3 blocks was developed using an online randomization tool. In the study, the group to which the first participant was assigned was determined by a sealed envelope method.

Design outcomes

Primary

MeasureTime frameDescription
Procedural pain score- Neonatal Infant Pain Scale (NIPS)1 min before the heel lance procedure (T-1 min), during the procedure (T+0 sec), 2 min (T+2 min) and 5 min (T+5 min) after the procedure; an average of 6 minutesThe scale is used to assess procedural pain in neonates. It is a behavioral scale assessing five behavioral indicators (facial expression, cry, arms, legs, and state of alertness) and one physiological indicator (breathing patterns). Five items (facial expression, breathing pattern, arms, legs, and state of alertness) are scored as 0 (Good) or 1 (Bad), while one item (crying) is scored as 0 (Good), 1, or 2 (Bad). The total scale score ranges from 0 to 7, with higher scores indicating more pain.

Secondary

MeasureTime frameDescription
Crying timeThrough painful procedure completion, an average of 5 minutesCrying time is the crying time between the moment of heel puncture and 5 minutes after the procedure.
Procedure timeThrough painful procedure completion, an average of 2 minutesThe duration of the procedure is the time between the moment of heel lance and the closure of the heel with gauze after the collection of capillary blood.
