PURPOSE
The aim of this study was to assess the clinical efficacy of combined treatment with local anesthesia and ketamine procedural sedation for pediatric facial laceration repair in the Emergency Department (ED).
METHODS
Patients aged 1 to 5 years receiving ketamine for facial laceration repair were prospectively enrolled in a double-blind, randomized, and controlled study at an ED. All patients were to receive intravenous ketamine (2 mg/kg). The local anesthesia group (LA group) received a local anesthetic along with ketamine, whereas the no local anesthesia group (NLA group) received only ketamine. The total time of sedation, the patients' movements and groans, adverse events, and the satisfaction ratings of physicians, nurses, and parents were recorded.
RESULTS
A total of 186 patients were randomized (NLA group: 90, LA group: 96). The total time of sedation (30.5 minutes for the NLA group, 32.6 minutes for the LA group; p=0.660), patients' groans (26 (28.9%) versus 23 (24.0%); 0.446) and movements (27 (30%) versus 35 (36.5%); p=0.350) was not affected by the addition of local anesthesia. Other adverse events were similar between the two groups. Also, the satisfaction ratings of physicians (median 4 for the NLA group versus 4 for the LA group (p=0.796)), nurses (2 versus 2.5 (p=0.400)), and parents (4 versus 4 (p=0.199)) were equivalent between the two groups.
CONCLUSION
In this study, we found that local anesthesia was not required along with ketamine sedation for pediatric facial laceration repair.

PURPOSE
Traumatic head injury is very common in the emergency room. Early diagnosis and treatment can significantly reduce mortality and morbidity. When diagnosis is delayed, however, it could be critical to the patients. In reality, it is difficult to take a brain CT for all patients with head trauma, so this study examined the relationship between type and size of scalp injury and intracranial injury.
METHODS
This prospective study was conducted from May 2005 to July 2005. The participants were 193 patients who had had a brain CT. Head trauma included obvious external injury or was based on reports of witnesses to the accident. Children under three years of age were also included if there was a witness to the accident. The size of the injury was measured based on the maximum diameter.
RESULTS
Out of the total of 193 patients, patients with scalp bleeding totaled 126 (65.2%), and patients without scalp bleeding totaled 67 (34.8%). Among patients with scalp bleeding, patients with intracranial injuries numbered nine, and among patients without scalp bleeding, patients with intracranial injuries numbered 17 (P=0.001). Among patients who showed evidence of scalp swelling with no scalp bleeding, the relationship between the size of the scalp swelling and intracranial injury was statistically significant when the size of the scalp swelling was between 2 cm and 5 cm.
CONCLUSION
Among patients who visit an emergency medical center due to traumatic head injury, patients with no scalp bleeding, but with scalp swelling between 2 cm and 5 cm, should undergone more accurate and careful examination, as well as as a brain CT.
