[Clinical evaluation of oral midazolam sedation for dental treatment in children].

Objective: To assess the safety, effectiveness and acceptability of oral midazolam sedation for dental treatment in children.

Methods: Twenty-three health children aged 4 to 14 (ASA I), who were classified as 4 or 5 by modified Venham's clinic anxiety and cooperative behavior rating scale, referred for dental treatment were included in the study. Each child was treated under sedation with oral midazolam (0.

[Effects of different concentrations of glucose infusion during the cleft lip and palate repair in infant patients].

Objective: To analyze the feasibility of regular infusion with different concentrations of dextrose and blood glucose monitor in infant from 2 to 12 months during operation.

Methods: Ninety ASA(American Society of Anesthesiologists) I-II infants (age 2-12 months) who undertook cleft lip and palate repair (excluding patients with congenital diabetes) were divided into three groups (30 cases per group). Group I patients were infused with normal saline, Group II with 2.

[Efficacy and safety of low-energy QS Nd:YAG and QS alexandrite laser for melasma].

Objective: To assess the efficacy and safety of low-energy QS Nd : YAG and QS alexandrite laser for melsasma.

Methods: We treated 32 patients with melasma using the low-energy QS Nd : YAG and QS alexandrite laser. Pigment subsided by > or = 90% was regarded as "cured", by 60% -89% as "remarkably improved", by 30% -59% as "effective", and by < 30% as "ineffective" .

[Comparison of antalgic effects of patient-controlled intravenous lornoxicam and sufentanil in patients after oral maxillofacial surgery].

Objective: To compare the analgesic efficiency and adverse effects of postoperative patient-controlled intravenous analgesia (PCIA) with lornoxicam and sufentanil in patients undergoing oral maxillofacial surgery.

Methods: 200 ASA (American Society of Anesthesiologists) I-II patients who undertook oral maxillofacial operation were divided into two groups: lornoxicam group (group L) and sufentanil group (group S), with 100 patients in each group. The effectiveness was assessed with visual analogue scale (VAS), Prince-Henry score (PHS) and Ramsay sedation Score (RSS) at different time points: 4, 8, 12, 24 and 48 h after the beginning of analgesia.
