Objectives: The objectives were to determine whether pretreatment with needleless jet-delivered lidocaine decreases self-reported pain in children undergoing needle insertion in the emergency department (ED) and to explore whether pretreatment with a jet device decreases self-reported pain in children undergoing needle insertion in the ED. Methods: This study examined needle insertion pain in children 5-18 years of age. In the first phase of this study, children received either pretreatment with jet-delivered lidocaine (0.2 mL of buffered 1% lidocaine; n = 75) or pretreatment with jet-delivered placebo (0.2 mL of preservative-free normal saline; n = 75) 60 seconds before undergoing needle insertion. This phase of the study had a randomized, double-blind, placebo-controlled design. In the second phase, an unblinded, nonconcurrent, nonintervention control group (n = 47) was examined to describe any effect of using the jet device. Patients reported pain upon administration of the jet device and at needle insertion using a 100-mm color analog scale (CAS). Patients also reported their satisfaction with this device. The physicians and nurses performing needle insertions were asked to rate their ability to visualize the vein and their satisfaction with the device. Results: The mean (+/-standard deviation [SD]) needle insertion pain score for jet lidocaine, 28 (+/-7) mm, was similar to the mean needle insertion pain score for jet placebo, 34 (+/-7) mm. The mean needle insertion pain score for both the jet lidocaine and the jet placebo groups were lower than the needle insertion pain scores for the no device group, 52 (+/-8) mm. The majority of patients receiving the jet device reported that they would request this device for future needle insertions. Providers' ratings of their ability to visualize veins and the patient cooperation were similar in all three groups. Conclusions: Jet-delivered lidocaine is no more effective than jet-delivered placebo in providing local anesthesia for needle insertion. Jet lidocaine and jet placebo may provide superior analgesia compared to no local anesthetic pretreatment

METHODS: A cohort of children younger than 18 years presenting to an urban pediatric emergency department (PED) who underwent psychiatric consultation was analyzed. A standardized data collection sheet was prospectively completed and included: patient characteristics, extent of medical evaluation and findings, ancillary diagnostic studies, resources utilized, dangerous behaviors, and disposition. RESULTS: Two hundred ten patients required psychiatric evaluation. Median age was 14 years; 51.9% were boys; 71.9% had a past psychiatric history; 39.0% had prior psychiatric admission(s), and 40.5% were on psychiatric medications. The admission rate was 49.5%. Patients spent a median of 5.7 hours in the PED. Hospital police monitored 51.9% patients. Forty-five patients had 91 dangerous behaviors. Those patients presenting with a complaint of aggressive behavior (P = 0.00006), a past psychiatric history (P = 0.003), or a history of prior psychiatric hospitalization (P = 0.005) were more likely to have dangerous behaviors. Two hundred nine patients underwent a complete medical evaluation, and 207 were considered medically cleared. Patients who had diagnostic evaluations for medically indicated reasons were significantly more likely to have abnormal results than those requested by the psychiatric consultant for screening purposes (43.6% vs. 9.2%; relative risk, 2.33; 95% confidence interval, 1.33-4.08) but were not statistically more likely to result in medical intervention (5.4% vs. 0%, P = 0.243). CONCLUSIONS: PED patients requiring psychiatric consultation and psychiatric admission had a prolonged PED stay and a high incidence of dangerous behaviors requiring intervention. History and physical examination adequately identified medical illness. Laboratory evaluation obtained for psychiatric transfer or admission purposes was of low yield
