Clinical Trial Summary

Background: Performance of endoscopy in children requires more patience, experience, and expertise than in adults. The anxiety of the children is related to parent's separation, loss of self-control, unknown surroundings and strange people that are taking care of them, and frequently unpleasant or even painful procedures. Painful and frightening procedures in children have been shown to result in short-term physiologic changes and long-term behavioral changes. The response to unpleasant stimuli with stress and fear may be exaggerated in children and experienced as pain. Most infants and children and many teenagers need deep sedation or light general anesthesia to complete a successful and safe procedure. Induction of general anesthesia is a stressful procedure itself. Strategies to reduce preanesthesia anxiety include pharmacologic and non-pharmacologic interventions.

However, this evidence is based mainly on self reports rather than objective measurements. Therefore, objective and non-invasive measurements to be utilized in the current study, should provide an assessment tools regardless the children's age.

Multiple studies, beginning in the 1970's, have shown that humor has many positive effects on physical and mental health and well-being. Previous investigations have reported that humor has beneficial effects on the immune system, stress related to potentially fatal illnesses, pain tolerance, and mental functions.

Dream doctors (DDs) are professional medical clowns or stage artists, who received training specifically to understand medical patient's need and to give the patient adjuvant therapy during hospital admissions or ambulatory treatment.The Israel dream doctors project, integrates professional medical clowning into the medical services provided at Israeli hospitals.Studies already proved that presence of medical clowns significantly reduces the level of anxiety during induction of anesthesia in children. Hypothesis of the study: 1) DDs lessen the level of anxiety and attention impairment in children undergoing gastroscopies. 2) DDs improve the satisfaction of children and their parents during gastroscopies.

The aim of this study is: 1) To explore the influence of DDs on the satisfaction of children and their parents undergoing gastroscopy, utilizing questioners. 2) To explore the effects of DDs on anxiety and attention of children and their parents, undergoing gastroscopies by means of GSR, startle response and pre-pulse inhibition (PPI) tests, as well as , and measuring anxiety-related biologic indices.

Description:

The effect of Dream Doctors in children undergoing digestive endoscopic procedures:

Physiological and biological assessment of emotional and cognitive consequences.

Background: Since the advent of pediatric gastrointestinal endoscopy in the early 1970's, there has been a remarkable increase in the number of diagnostic and therapeutic procedures performed in infants and children. Performance of endoscopy in children requires more patience, experience, and expertise than in adults. The anxiety of the children is related to parent's separation, loss of self-control, unknown surroundings and strange people that are taking care of them, and frequently unpleasant or even painful procedures. Painful and frightening procedures in children have been shown to result in short-term physiologic changes and long-term behavioral changes. The response to unpleasant stimuli with stress and fear may be exaggerated in children and experienced as pain. Most infants and children and many teenagers need deep sedation or light general anesthesia to complete a successful and safe procedure. Induction of general anesthesia is a stressful procedure itself. Strategies to reduce preanesthesia anxiety include pharmacologic and non-pharmacologic interventions.

However, this evidence is based mainly on self reports rather than objective measurements. Therefore, objective and non-invasive measurements to be utilized in the current study, should provide an assessment tools regardless the children's age.

Multiple studies, beginning in the 1970's, have shown that humor has many positive effects on physical and mental health and well-being. Previous investigations have reported that humor has beneficial effects on the immune system, stress related to potentially fatal illnesses, pain tolerance, and mental functions.

Dream doctors are professional medical clowns or stage artists, who received training specifically to understand medical patient's need and to give the patient adjuvant therapy during hospital admissions or ambulatory treatment. Laughter has physiological effects on different body mechanisms and it affects the cardiovascular system (decreasing heart rate and blood pressure), strengthens the immune system, and lowers level of stress hormones like Norepinephrine. Humor can also help in strengthening the bond between therapist and patient and reduce stress and anxiety and enhance recovery. The Israel dream doctors project, integrates professional medical clowning into the medical services provided at Israeli hospitals. The DDs are part of the multidisciplinary staff, principally but not only, in pediatric wards. Studies already proved that presence of medical clowns significantly reduces the level of anxiety during induction of anesthesia in children. In the pediatric ward in Afula Medical Center, the investigators have experience with DDs for preparing children to kidney scans.

Pre-Puls Inhibition PPI A computerized human startle response monitoring system (SR-HLAB STARTLE REFLEX, San Diego Instruments, San Diego, CA) was used to deliver acoustic startle stimuli via headphones and record and score the corresponding electro myographic activity from the orbicularis oculi muscle. Two disposable electrodes (sensor area 12 mm2) were placed approximately 0.75-1cm below the pupil on the orbicularis oculi muscle and 3rd reference electrode on the mastoid bone. The skin area at the electrode site was cleaned with a cotton swab saturated with rubbing alcohol, then prepared by gently rubbing a small amount of EEG & ECG Skin Prepping Gel (Signa Gel- Parker Laboratories Inc., Fairfield, New jersey, USA), and cleaned again with a cotton swab.

The session (a total of 56 trials) is started with 3 min acclimatization period with a 60 dB background noise level that is delivered continuously throughout the test session. The session is comprised from two blocks. block1: comprised from randomly delivered six trials of single 40 msec 120 dB "pulse alone" startle stimuli in order to evaluate the startle response, ten "pre" stimuli (at 74, 78, 82, 86 or 92 dB), and thirty "pre pulse" trials that consisted of a single 120 dB pulse preceded (120 msec inter-stimulus-interval) by a 20 msec pre pulse of 14, 18, 22, 26 or 32 dB above background (i.e., 74, 78, 82, 86 or 92 dB). Block1 trials were delivered on average 20 sec inter-trial-interval ITI (15-25 sec, total 46 trials). Block2: comprised of the last ten trials of "pulse alone" startle, at fixed 2 sec ITI in order to evaluate a measure of habituation in response to repeated delivery of the startling stimuli. Finally, prepulse inhibition (PPI) was calculated as the percent of the habituated response as follows [100-(max response to "pre pulse" trial / max response to "pulse alone" trial X 100)]

GSR - Galvanic Skin Response Electrodermal activity will be measured by the differences of the skin conductivity. Two 5 mm electrodes will be placed on fingers 2 and 4 of the non-dominant hand. The electrodes will be connected to sensor and amplifying receiver with a 10Hz sampling rate.

Different portions of the skin can show differences in conductivity, due to sweat related to stress. Thus, measuring the skin conductivity of the non-dominant hand was shown to reduce this variability.

Hypothesis of the study: 1) DDs lessen the level of anxiety and attention impairment in children undergoing gastroscopies. 2) DDs improve the satisfaction of children and their parents during gastroscopies.

The aim of this study is: 1) To explore the influence of DDs on the satisfaction of children and their parents undergoing gastroscopy, utilizing questioners. 2) To explore the effects of DDs on anxiety and attention of children and their parents, undergoing gastroscopies by means of GSR, startle response and pre-pulse inhibition (PPI) tests and measuring anxiety-related biologic indices.

Patients and Methods: This randomized, controlled study will be conducted with children undergoing deep sedation during pediatric upper gastrointestinal endoscopies in the Gastroenterology institute of the Emek Medical Center,Afula, Israel. One hundred children (age 1-18 years) scheduled to undergo deep sedation and elective gastroscopy will be enrolled. During enrollment, the potential clown involvement will be explained to parents. Patients will be assigned to one of two groups: Group 1:children and their parents with the presence of DD upon arrival to the Gastroenterology institute and throughout the induction of sedation, gastroscopy and recovery. Group 2: children and their parents undergoing gastroscopy with deep sedation without the presence of a DD.

The randomization process: In Afula Medical Center, the investigators perform gastroscopies weekly. During the study period the investigators will perform the gastroscopies one week with the DD and one week without the DD.The patients will not be aware to that fact that in some weeks the DD is participating during the sedation induction in some of the patients (every other week). The DD will use various methods for entertaining the child and alleviate stress according to the child's age. The parents and the children will be given anxiety questioners to fill before the induction of sedation. At the end of the gastroscopy the parents and the children will be given satisfaction questioners. The children will perform Pre-Pulse inhibition (PPI) test and GSR before and after the gastroscopy to assess physiological and biological emotional and cognitive consequences. The parents will perform PPI test and GSR before, during and after the gastroscopy (no caffeine or nicotine consumption will be allowed 30min before examination). The anesthesiologist and the nurse at the recovery room will fill a questioner evaluating the behavior of the child during the induction of sedation and awakening. While inserting an IV line blood spots will be taken for stress hormones: cortisol, epinephrine, and norepinephrine. The following physical indices will be measured: blood pressure, pulse, saturation and body temperature. The amount of drugs given for deep sedation will be evaluated.

The current study hold two major innovativeness: (a) The effects of DD as part of the medical team in gastroscopy in children. (b) The physiological and biological evaluation of the emotional and cognitive consequences in children and their parents during gastroscopy.

Statistical analysis:

The study design is Mixed design (2X3), with DD as between subject factor (with or without DD) and stage of treatment as within subject factor (prior, during and after gastroscopy examination).Thus, we will conduct a Two-Way ANOVA (2X3) with post hoc Tukey's test. Significant interactions will be further analyzed with One-Way ANOVA. Moreover to relate physiological and biological measurement to questioner items, Pearson's correlations will be calculated.
