One hundred infants were divided into the following 3 gestational age (GA) groups: (I) premature infants (n = 30) with the gestational age between 29 and 32 weeks; (II) premature infants (n = 30) with the gestational age between 33 and 36 weeks; (III) full-term infants (n = 40). The recorded responses of all infants to pain included the behavioral responses to painful stimuli (cry, facial activity and limbs movement) and the variety of heart rate. ⋯ Pain expression in full term infants was more significant than premature infants to same stimuli. 33-weeks GA infants were differential from 29-weeks GA infants. Full term infants showed more vertical mouth stretch and more taut tongue and more hand to mouth than premature infants, but more horizontal mouth stretch in premature infants.

Comparative StudyA comparative study on the close reduction of arytenoid dislocation under indirect and direct laryngoscope.
To assess the curative effects of different reduction techniques on the dislocation of cricoarytenoid joint caused by intubation, indirect laryngoscope (IL) and direct laryngoscope (DL) were utilized for the closed reduction of the displaced arytenoid under local anesthesia. 23 patients who underwent the reduction for dislocated arytenoid under IL or DL from January 1991 to June 2001 were reviewed. The data were collected on the duration of the laryngeal injury, times of receiving reduction, side-effects after the treatment and the period for voice to return to normal. The relationship between the duration of the laryngeal lesion and the period of the voice rehabilitation was examined. 13 patients received the reduction under IL and 10 patients under DL. ⋯ It is concluded that the recovery of normal voice is obviously affected by the duration of arytenoid dislocation. The reduction under IL is as effective as under DL in the treatment of arytenoid dislocation. Reduction by DL is better suit the patients with long time course of disease.
