ABSTRACT
Objective@#Subthreshold attention-deficit/hyperactivity disorder (ADHD) has been suggested to be a “morbid condition” which also needs medical attention. @*Methods@#The present study recruited 89 children with subthreshold ADHD (sADHD), 115 children with diagnosed ADHD (cADHD), and 79 healthy controls (HC) to explore the clinical manifestation, executive functions (EFs) of sADHD, and the caregiver strain. The clinical manifestation was evaluated through clinical interviews and parent-reports. Executive functions were assessed both experimentally and ecologically. Caregiver strain was measured by a parent-reported questionnaire. @*Results@#For the clinical manifestation, both sADHD and cADHD indicated impairments when compared with HC. The comorbidities and the scaled symptoms indicated that the externalizing behaviors were relatively less serious in sADHD than cADHD, whereas the internalizing behaviors between two groups were comparable. For ecological EFs, sADHD scored between cADHD and HC in inhibition and working memory. For experimental EFs, sADHD was comparable to cADHD in inhibition, shifting, and was worse than cADHD in verbal working memory. For the caregiver strain, all scores of sADHD were between that in cADHD and that in HC. @*Conclusion@#Our present findings supported the suggestion of subthreshold ADHD as “morbid condition,” which should be treated with caution in clinical practice, especially for the internalizing behaviors and some key components of EFs.
ABSTRACT
Objective:To evaluate the efficay of different doses of remimazolam for anesthesia induction during reoperation in asthenic patients with tracheotomy.Methods:One hundred and twenty patients of both sexes, aged 19-64 yr, with a modified frailty index score ≥3, of American Society of Anesthesiologists physical status Ⅳ, scheduled for reoperation after tracheotomy, were divided into 4 groups ( n=30 each)using a random number table method: propofol group (group C) and different doses of remimazolam groups (R 1, R 2 and R 3 groups). Anesthesia was induced with intravenous sufentanil 5 μg, propofol 1.5 mg/kg in group C and with remimazolam 0.1, 0.2 and 0.3 mg/kg in R 1, R 2 and R 3 groups, respectively.The tracheotomy cannula was replaced with a reinforced endotracheal intubation (ID=6.0 mm) when bispectral index value ≤ 65.Mean arterial pressure and heart rate were recorded before induction (T 0), immediately before replacement of the tube (T 1) and immediately after replacement of the tube (T 2). The onset time of anesthesia and adverse reactions such as hypotension, bradycardia and bucking during replacement of the tube, and requirement for rescue sedation were recorded. Results:Compared with group C, mean arterial pressure was significantly increased at T 1, 2 in group R 1 and group R 2, the onset time of anesthesia was significantly prolonged, the incidence of hypotension and bradycardia was decreased in R 1, R 2 and R 3 groups, and the requirement for rescue sedation in group R 1 and incidence of bucking in group R 1 and group R 2 were increased ( P<0.05 or 0.01). Compared with group R 1, heart rate at T 2 was significantly decreased, the onset time of anesthesia was shortened, and the requirement for rescue sedation and incidence of bucking were decreased in C, R 2 and R 3 groups, and the incidence of hypotension was significantly increased in group R 3 ( P<0.05 or 0.01). Compared with group R 2, the onset time of anesthesia was significantly shortened in group R 3 ( P<0.05). Conclusions:Remimazolam 0.2 mg/kg provides good efficacy when used for anesthesia induction with fewer side effects during reoperation in asthenic patients with tracheotomy.
ABSTRACT
Objective:To develop and test the reliability and validity of the assessment scale for patients with persistent vegetative state (PVS) or minimally conscious state (MCS) discharge from the anesthesia recovery room after operation.Methods:From September 2018 to October 2020, three dimensions and 17 item pools were determined through literature review and discussion among the project members. Two rounds of expert consultation were conducted to determine the respiratory (R), circulatory (C), oxygenation (O), bispectral index (B) and neuromuscular monitoring (N) scale (RCOBN scale), the reliability and validity were tested. 87 patients with PVS or MCS after operation Affiliated Sichuan Bayi Rehabilitation Center of Chengdu University of Traditional Chinese Medicine were selected to verify the effectiveness.Results:In the first round, 23 questionnaires were distributed. The total score of experts was 50 ± 3, F=9.24, CV were 0.00-0.43. The Cronbach α coefficient of each dimension was 0.782-0.846, and the Cronbach α coefficient of the total scale was 0.813. In the second round, 10 questionnaires were distributed. The item-level content validity index was 0.7-1.0, the probability of random consistency ( Pc) was 0.001-0.117, the adjusted kappa value ( k*) was 0.567-1.000, and the sum of the index scores corresponding to k* > 0.74 was 8. The scale-level content validity index of the overall consistency was 0.87. The ratio of patients transferred out of PACU by two rounds of evaluation method was 100 : 96.55, and the difference was not statistically significant ( χ2=3.05, P>0.05). The time of the first round of assessment was significantly longer than that of the second round, which were (197 ± 52) s and (58 ± 14) s respectively. The difference was statistically significant ( t=26.52, P < 0.01). Conclusions:The RCOBN scale has high reliability and validity. It can be used as an assessment scale for patients with PVS or MCS to transfer out of PACU after surgery, and those with a total score of 8 can be transferred out of PACU.
ABSTRACT
Objective:To evaluate the efficacy of remimazolam combined with low-dose propofol for sedation during induction of anesthesia.Methods:A total of 228 patients of both sexes, aged 18-64 yr, with body mass index of 19-35 kg/m 2, of American Society of Anesthesiologists physical status Ⅰ-Ⅲ, undergoing elective laparoscopic cholecystectomy, were divided into 2 groups ( n=114 each) by a random number table method: remimazolam combined with low-dose propofol group (group R) and propofol group (group P). Anesthesia was induced with intravenous injection of sufentanil 0.3 μg/kg, remimazolam 0.3 mg/kg, propofol 0.5 mg/kg and micuronium 0.2 mg/kg in group R, and sufentanil 0.3 μg/kg, propofol 2 mg/kg and micuronium 0.2 mg/kg in group P. Endotracheal intubation was performed when bispectral index value ≤ 50.Before induction (T 0), immediately before intubation (T 1), at 1 min (T 2) and 3 min (T 3) after intubation, mean arterial pressure (MAP) and heart rate (HR) were recorded.The anesthesia induction time and the incidence of hypotension and bradycardia were recorded in the two groups. Results:There was no significant difference in MAP and HR at T 0 between the two groups ( P>0.05). Compared with the value at T 0, MAP in two groups and HR were significantly decreased at T 1-3 in group P ( P<0.01). Compared with group P, the anesthesia induction time was significantly prolonged, and hypotension and bradycardia was decreased in group R ( P<0.05). Conclusion:The combination of remimazolam and low-dose propofol exerts better efficacy for sedation during induction of anesthesia than propofol alone.
