A randomized controlled trial on virtual reality distraction during venous cannulation in young children.

BACKGROUND AND OBJECTIVES: Pain management in children is often inadequate, and the single most common painful procedure in children who are hospitalized is needle procedures. Virtual reality (VR) has been shown to decrease anxiety and pain in children undergoing painful procedures primarily in children from the age of 7 years. Our aim for this study is to investigate patient satisfaction and pain reduction by using a three-dimensional VR interactive game as a distraction in 4-7 years old children during venous cannulation. METHODS: In this randomized clinical trial, we enrolled 106 children aged 4-7 years who were scheduled for venous cannulation. Patients assigned to the control group were adherent to standard of care, including topical numbing cream, positioning, and distraction in this group by games of choice on a tablet/smartphone. In the study group, children were adherent to standard of care and were distracted by an interactive VR game. Primary outcomes were patient satisfaction and the procedural pain assessed by using Wong-Baker Faces Pain Rating Scale; secondary outcomes were the procedural time and any adverse events. RESULTS: We found an overall high level of patient satisfaction with our regime of topical numbing cream, positioning, and distraction. The primary outcome of pain during the procedure was median 20 mm (IQR 0-40) and 20 mm (IQR 0-55) (Wong-Baker 0-100 mm) in the VR group and the control group, respectively (difference: 0 mm, 95%CI: 0-20, p = .19). No significant difference was found in procedural times. The number of adverse effects was low, with no significant difference between the two groups. CONCLUSIONS: VR distraction is an acceptable form of distraction for children 4-7 years old when combined with topical numbing cream and positioning during preoperative venous cannulation. No difference was found between VR- and smartphone/tablet distraction.

Structured intervention for management of pain following day surgery in children.

BACKGROUND: Ambulatory surgery forms a large part of pediatric surgical practice. Several studies indicate that postoperative pain is poorly managed with more than 30% of children having moderate to severe pain. In a busy outpatient clinic contact between healthcare professionals and the family is increasingly limited calling for a global and efficient pain management regime. OBJECTIVE: The aim of this prospective observational cohort study was to determine postoperative pain intensity following day surgery in children after our structured intervention for pain management. METHODS: A number of interventions in an effort to address barriers to effective postoperative pain management after day surgery were identified in the literature. By introducing our concept structured intervention, we aimed to address the majority if not all these barriers. Accordingly, we adapted postoperative pain management to each child using a multimodal approach consisting of surgery-specific analgesia with weight appropriate doses of acetaminophen and ibuprofen. Analgesics were handed out to the parents in formulations accepted by child and parent and after thorough information to the parents. RESULTS: Two hundred and forty-five children were scheduled for surgery during the 3-month period of which 149 children were available for analysis. The postoperative pain as assessed by the parents with a the Short Form of the Parents' Postoperative Pain Measure (PPPM-SF) was well managed exhibiting a median pain score of 4 on postoperative day 0 (POD0) and median 1 on postoperative day 1 (POD1) and a numeric rating scale (NRS) median pain score of 2 on POD0 and median 1 on POD1. We found a highly significant correlation between the PPPM-SF and the NRS scores. CONCLUSION: After thorough information of the parents we have successfully implemented a surgery-specific regime of primarily around-the-clock dosing of drug formulations acceptable for the specific child with dispensed medication ready available for the family.

Long-term biopsychosocial issues and health-related quality of life in young adolescents and adults treated for childhood Complex Regional Pain Syndrome, type 1.

OBJECTIVES: Treatment for childhood Complex Regional Pain Syndrome (CRPS) is associated with long-term recovery. The present study aimed to investigate the long-term biopsychosocial status and quality of life in young adolescents and adults after the treatment of childhood CRPS. METHODS: A 4 year follow-up of individuals with childhood-CRPS, type 1 (n=22; age:12 years (years) [median] at treatment and 17 years at follow-up) was completed. Biopsychosocial status and quality of life were assessed with structured interviews, using the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV), the Strengths and Difficulties Questionnaire (SDQ), the Pediatric Pain Coping Inventory (PPCI), and the Pediatric Quality of Life Inventory (PedsQL). Comparisons were made with normative samples of age-matched controls. RESULTS: CRPS at follow-up was still present in seven out of 22, and non-CRPS pain symptoms were found in 12 out of 22 individuals. Signs of mental health pain-related problems, including phobias and obsessive-compulsive disorder, were observed in ten out of 19 individuals. Mental well-being, social functioning, and quality of life (SDQ and PedsQL) were independent of pain status (p>0.05). Adaptive pain coping strategies were utilized regardless of pain status (PPCI). Social functioning (p<0.01) and the quality of life (p=0.01) were attenuated and statistically significantly poorer than healthy age-matched young adults but better than for fibromyalgia subjects. CONCLUSIONS: A subset of individuals treated for childhood-CRPS, type 1 experiences long-term consequences of persistent pain, a decrease in quality of life indicators, and demonstrates significant psychosocial issues. Childhood-CRPS is suggested to be associated with long-term psychosocial consequences and poorer quality of life than found in age-related healthy peers. Subjects treated for childhood CRPS may need a longer clinical follow-up attempting to preclude relapse of CRPS and non-CRPS pain.

Immersive Virtual Reality for Pediatric Procedural Pain: A Randomized Clinical Trial.

BACKGROUND AND OBJECTIVES: Pain management in children often is inadequate, and the single most common painful procedure in children who are hospitalized is needle procedures. Virtual reality (VR) is a promising and engaging intervention that may help to decrease anxiety and pain in children undergoing painful procedures. Our aim for this study is to investigate patient satisfaction and pain reduction by using a three-dimensional VR interactive game as a distraction. METHODS: In this randomized clinical trial, we enrolled 64 children aged 7 to 16 years who were scheduled for venous cannulation. Patients assigned to the control group were adherent to our standard of care, including topical numbing cream, positioning, and distraction by a specialized pain nurse. In the study group, children were adherent to the standard of care and were distracted by an interactive VR game. Primary outcomes were patient satisfaction and the procedural pain assessed by using a visual analog score; secondary outcomes were the procedural time and any adverse events. RESULTS: We found a high level of patient satisfaction with using the VR custom-made three-dimensional interactive game. All children (28 of 28 [100%]) in the VR group answered that they would prefer VR as a distraction for a later procedure, a borderline significant result compared with that of the control group (26 of 31 [84.9%]). No significant difference was found in pain scores and procedural times between the 2 groups. The number of adverse effects was low, with no significant difference between the 2 groups. CONCLUSIONS: We found no difference in pain scores but higher satisfaction when using VR versus standard care as part of a multimodal approach for management of procedural pain in children.

Topical morphine for oral mucositis in children: dose finding and absorption.

CONTEXT: Systemic opioids for painful chemotherapy-induced oral mucositis in children often result in unsatisfactory pain relief and a high frequency of side effects. Opioids applied topically can produce analgesia by binding to opioid receptors on peripheral terminals of sensory neurons. These receptors are upregulated during inflammation, for example, in oral mucositis. OBJECTIVES: The aims of this study were to investigate the dose-response relationship (n=7) and the potential absorption of topical morphine (n=5) across oral mucosa in children with oral mucositis. METHODS: The dose-response study was conducted according to a sequential study design (Dixon's Up-and-Down method) for topical morphine doses of 0.025-0.400mg/kg, with the decrease in oral pain score as the primary outcome. To assess potential absorption across oral mucosa after a single dose of topical morphine of 0.050mg/kg, blood samples were drawn and the plasma concentrations of morphine and metabolites were determined by high-pressure liquid chromatography. RESULTS: A decrease in oral pain score of ≥36% was achieved in six of seven patients in the dose-response part of the study. Plasma concentrations of morphine and metabolites were well below effective analgesic levels. CONCLUSION: No obvious dose-response effect was found for topical morphine doses of 0.025-0.400mg/kg, and topically applied morphine was not absorbed in clinically relevant doses. However, this study was limited by the small number of patients and the allowance of a systemic opioid as rescue medication. Thus, randomized controlled studies are needed to further investigate the analgesic properties of topical morphine.
