To analyze the efficacy and safety of different doses of esketamine for laparoscopic high hernia sac ligation in school-age children.
The school-age children who underwent laparoscopic high ligation of hernia sac were divided into small-dose group and conventional-dose group according to cohort method. The conventional-dose group was given intravenous 0.75 mg·kg-1 esketamine hydrochloride injection to prepare for induction; the small-dose group was given intravenous 0.50 mg·kg-1 esketamine hydrochloride injection to prepare for induction, and the two groups were given the same anesthesia induction, anesthesia maintenance and postoperative analgesia. The recovery time, laryngeal mask removal time, anesthesia recovery room residence time, children face, legs, activity, cry, consolability behavioral tool (FLACC) score of the children in the two groups were observed, the hemodynamic indexes were recorded at the time of entry (T1), before anesthesia induction (T2), immediately after laryngeal mask placement (T3), and the safety was evaluated.
A total of 39 cases and 43 cases children were included in the conventional-dose group and the small-dose group, respectively. After treatment, the recovery time of conventional-dose group and small-dose group were (26.36±3.91) and (23.21±3.55) min; the time of removing laryngeal mask were (13.02±2.15) and (12.24±2.30) min; the retention time of postanesthesia care unit (PACU) were (37.23±5.64) and (32.11±5.36) min; the scores of FLACC were (2.08±0.45) and (2.16±0.51) points, respectively. At T1, T2 and T3, the heart rate (HR) of the conventional-dose group were (99.23±15.78), (102.19±17.20) and (118.30±14.96) beat·min-1; that of the small-dose group were (99.93±16.27), (103.28±16.75) and (120.19±15.39) beat·min-1, respectively. The mean arterial pressure (MAP) of the conventional-dose group were (84.56±7.22), (85.92±6.96) and (89.89±7.02) mmHg; that of the small-dose group were (84.88±6.87), (86.16±6.45) and (91.12±7.31) mmHg, respectively. There were statistically significant differences in the recovery time and PACU retention time between the small-dose group and the conventional-dose group (all P<0.05). The adverse drug reactions in the two groups mainly included nausea and vomiting, increased secretions and transient hypertension. The incidence of total adverse drug reactions in the conventional-dose group and the small-dose group were 10.26% and 4.65%, respectively, with no statistical significance (P>0.05).
Small-dose esketamine hydrochloride injection can effectively maintain hemodynamic stability in the preoperative intravenous administration of school-age children undergoing laparoscopic high ligation of hernia sac, and the effect of reducing postoperative pain and inhibiting agitation during the recovery period is comparable to that of conventional-dose, with good safety.
To explore the clinical effects and influencing factors of recombinant human growth hormone (rhGH) treatment in pediatric patients with growth hormone deficiency.
The study subjects were pediatric patients with growth hormone deficiency, all of whom received a combination therapy of stanozolol tablets 2 mg (qd) and 0.1 U·kg-1·d-1 of recombinant human growth hormone injection for a continuous period of one year. After one year, the patients were divided into active group and invalid group based on clinical outcomes. Comparisons were made between the two groups in terms of height, annual growth velocity (GV) and height standard deviation score (HtSDS) before and after treatment, and safety evaluations were conducted. Multivariate Logistic regression analysis was used to identify factors that influenced the treatment outcomes in pediatric patients with growth hormone deficiency.
After one year of treatment, a total of 93 cases pediatric patients were included in the analysis, with 62 cases in the active group and 31 cases in the invalid group. The heights of the patients before and after treatment were (119.40±2.48) and (129.08±2.37) cm, respectively; the GV were (3.08±0.39) and (7.34±1.02) cm·year-1, respectively; the HtSDS were -2.45±0.49 and -1.68±0.35, respectively, with statistically significant differences observed for all comparisons (all P<0.05). In the active and invalid groups, the proportions of patients with GV<3.0 cm·year-1 before treatment were 32.26% and 58.06%, respectively; the proportions of patients with peak growth hormone (GH) levels <5.0 ng·mL-1 before treatment were 30.65% and 54.84%, respectively; the average maternal heights were (158.83±5.76) and (155.48±6.58) cm, respectively, with statistically significant differences observed for all comparisons (all P<0.05). The results of the Logistic regression model showed that GV<3.0 cm·year-1 before treatment, peak GH levels <5.0 ng·mL-1 before treatment, and a shorter maternal height were independent risk factors for poor treatment outcomes with rhGH in pediatric patients with growth hormone deficiency (all P<0.05). No severe adverse reactions occurred during the treatment of any patient; seven patients experienced pain at the injection site, one patient had a slight increase in blood glucose, and five patients had mild decreased appetite. The total incidence of adverse drug reactions were 13.98% (13 cases/93 cases).
Treatment with rhGH for pediatric patients with growth hormone deficiency can significantly improve height development and has good safety, but it is influenced by factors such as growth velocity, peak GH levels, and maternal height.
