Randomized Controlled Trial Clinical Trial
The effect of order on pain of local anesthetic infiltration.
To define the relationship between order of injection and pain of infiltration of buffered lidocaine. ⋯ The second injection of buffered lidocaine was found to be statistically more painful than the first in this protocol that controlled for all variables except for order of injection. Future studies involving paired comparisons should take this information into account.

Randomized Controlled Trial Clinical Trial
Effectiveness of 50% nitrous oxide/50% oxygen during laceration repair in children.
To determine the effect of an inhaled 50% nitrous oxide/50% oxygen mixture on measures of observed anxiety in children during laceration repair. ⋯ Administration of a 50% nitrous oxide/50% oxygen mixture to children during their laceration repair resulted in a significant decrease in measures of anxiety when compared with inhalation of 100% oxygen.

Randomized Controlled Trial Clinical Trial
Does the use of topical lidocaine, epinephrine, and tetracaine solution provide sufficient anesthesia for laceration repair?
To determine: 1) the effectiveness of lidocaine, epinephrine, and tetracaine (LET) solution in eliminating or reducing the pain experienced in suturing superficial lacerations in adult patients; and 2) the effectiveness of LET in reducing the pain of local anesthetic injection. ⋯ Significantly fewer patients require an injectable anesthetic when LET is applied. Those who do require an injection may experience less discomfort. These advantages should be balanced against the 20 to 30 minutes necessary for the LET to take effect.

Randomized Controlled Trial Clinical Trial
Local anesthesia for lacerations: pain of infiltration inside vs outside the wound.
To compare the pains of infiltration of a local anesthetic for simple lacerations when used from within the wound vs through intact skin. ⋯ Local anesthesia is less painful when injected from within a laceration as compared with intact skin.

To examine the consistency of Australasian National Triage Scale (NTS) categorization in a large hospital ED, especially in relation to daily activity. ⋯ In this ED, triage categorization according to the Australasian NTS does not vary with daily activity and has been consistent over time. Further study in other settings is required, particularly to identify variation dependent on the presenting population.
