Brief summary

This study is being conducted to determine the effect of EMLA cream and cold application on pain, fear and vital signs before chest tube removal in children aged 7-18 years.

Detailed description

A chest tube is a device used to drain air or fluid from the pleural cavity under sterile conditions by inserting a thin or thick tube. Chest tubes adhere to the endothelium of the chest cavity after insertion and while in place. For this reason, the pulling force applied when they are removed breaks these adhesions and causes intense, localised and transient acute pain. Chest tube removal pain, defined as one of the patient's worst life experiences related to the surgical procedure, is an iatrogenic pain caused by an invasive procedure. Therefore, chest tube removal is a painful, anxious and frightening experience for the patient. There are few studies of pharmacological and non-pharmacological methods of pain control during chest tube removal in children. However, the management of pain associated with surgical procedures in childhood is very important for the management of pain, anxiety and fear that children will experience with future medical procedures.

Interventions

EMLA cream is applied once, 3 hours before the tube is removed. EMLA cream will be applied by the researcher in a thin layer to an area of 7-10 cm2, with the chest tube entrance to the skin remaining in the center. It will be covered with a Tegaderm transparent film dressing.

PROCEDURECold application

Cold application will be made with an ice cube pack immediately before the chest tube removal procedure. Cold application will be applied to a 7 cm diameter area, with the chest tube entrance to the skin being considered as the center. Skin temperature will be measured with an infrared thermometer and will be ensured to reach 13.0 degrees. Ice pack application is expected to last approximately 9-10 minutes.

Masking description

Using the block randomization technique, participants will be divided into 3 groups. A web-based randomization list creation tool will be used to create the blocked randomization list. Control and intervention groups will be coded as A, B and C using the sealed envelope method. Randomization information will be kept from the researcher involved in data collection until data collection begins. The researcher will learn which group each child is in just before the application (researcher blinding). Research data will be entered into the computer database by coding the group name as A, B and C, and statistical analysis will be performed using this coding (statistician blinding).

Intervention model description

Participants will be assigned to experimental and control groups using block randomization method. Age, sex and procedural fear variables will be used for block randomization. In order to reach the sample size calculated in the study, strata will be repeated two times (2X2X3X2) and 24 children will be included in each group.

Design outcomes

Primary

MeasureTime frameDescription
Procedural pain score- Wong-Baker FACES Pain Rating Scale3 hours before the procedure, immediately before the procedure, 1 minute after the procedure and 5 minutes after the procedureThe scale is used to diagnose pain in children aged 3-18 years. It consists of six facial expressions, each one representing an increasing degree of pain scored on a scale 0 to 5 from left to right. The first face is a happy face representing no pain=0 while the last face is a crying face representing the worst pain imaginable=5. Higher scores indicate low pain tolerance. Participants are asked to choose the facial expression that best represents their pain.

Secondary

MeasureTime frameDescription
Procedural fear score- Children's Fear Scale (CFS)3 hours before the procedure, immediately before the procedure, 1 minute after the procedure and 5 minutes after the procedureThe CFS was developed to measure fear and anxiety in children. It consists of five facial expressions that represent a range from neutral to extreme fear. It is scored between 0 and 4. Both researchers and family members can use the CFS to measure fear and anxiety in children before and during procedure.
Oxygen saturation3 hours before the procedure, immediately before the procedure, 1 minute after the procedure and 5 minutes after the procedureChildren will be connected to a pulse oximeter monitor; oxygen saturation will be monitored before, during and after the procedure.
Pulse rate3 hours before the procedure, immediately before the procedure, 1 minute after the procedure and 5 minutes after the procedureChildren will be connected to a pulse oximeter monitor; their pulse rate will be monitored before, during and after the procedure.
