Background: Pediatric patients undergoing minor, but painful procedures in an Emergency Department (ED) need adequate relief of pain and distress to prevent long term negative effects and adversely impact procedures. Inhaled nitrous oxide (NO) is a needle-free pain management option. We conducted a systematic review to determine whether NO is as effective as local anesthesia in minor procedures. The purpose of this study was to evaluate available evidence regarding analgesic effectiveness of NO in pediatric patients.
Methods: We searched MEDLINE, Embase, Cochrane and Cinahl databases for controlled trials published in English with pediatric patients in an ED treated with NO compared to local anesthesia and with pain as primary outcome. Adverse events was one of the secondary outcomes. The GRADE system was used to rate the overall quality of evidence.
Results: We included seven studies with a total of 371 patients. Two studies showed NO was equally effective in pain treatment as local anesthesia. Five studies showed NO combined with local anesthesia is more effective in reducing pain than local anesthesia alone. None of the included studies reported major adverse effects. The quality of evidence is low.
Conclusions: NO can have an important contribution in pain management, but should be combined with local anesthesia for optimal pain management in pediatric patients undergoing minor, but painful procedures in an ED.
Level Of Evidence: IV.

Tooth impaction and eruption failure present common challenges in pediatric dentistry. We report a case of a 10-year-old boy of Indian origin presenting with a missing left mandibular primary second molar and impacted first permanent molar. Radiographic examination revealed an ankylosed primary molar obstructing the path of an unerupted premolar.

Background: Paravertebral block (PVB) is effective in controlling postoperative pain after video-assisted thoracoscopic surgery (VATS) lobectomy but is subject to a high rate of failure because of incorrect site of injection. We compared methylene blue PVB with thoracic epidural anesthesia (TEA) for postoperative pain after VATS lobectomy.
Methods: We conducted a prospective randomized trial of patients undergoing VATS lobectomy; 120 patients were randomly assigned to the PVB or TEA group.

The aim of this study was to evaluate the efficacy and patient satisfaction of lidocaine aerosol for pain management during periodontal scaling and root planning in patients with chronic periodontitis or dental plaque-induced gingivitis. This study specifically concentrated on comparing the effectiveness of lidocaine aerosol as a topical anesthetic against a placebo, assessing its impact on pain perception during the procedure. Additionally, the relationship between periodontal treatment and the reduction of oxidative stress markers in these patients was assessed.

Objective: This study aims to map the existing sources of evidence on perioperative care and recovery strategies for primary cleft palate repair, to identify elements that should be included in an enhanced recovery pathway (ERP), and to identify gaps in current knowledge.
Design: Scoping review.
Setting: ERPs are evidence-based, patient-centered, multimodal, perioperative care pathways designed to reduce surgical stress and improve postoperative outcomes and are increasingly being reported in the cleft lip and palate literature.
