Objective To systematically evaluate effectiveness, dosage and adverse reaction of sufentanil versus fentanyl for postoperative patient-controlled epidural analgesia (PCEA), so as to provide evidence for rational drug use in clinic. Methods Databases including The Cochrane Library, the special trials registered in the Cochrane anesthesia group, MEDLINE, EMbase, CBM, CNKI, VIP and WanFang Data were searched by the end of 2012, and the relevant periodicals were also manually searched to collect the randomized controlled trials (RCTs) on sufentanil versus fentanyl for postoperative patient-controlled epidural analgesia. According to the Cochrane Handbook 5.0, literature was screened, data were extracted, and quality of the included studies was critically assessed. Then meta-analysis was performed using RevMan 5.1 software. Results A total of 25 RCTs involving 1 944 patients were included. The results of meta-analyses showed that: a) as for visual analog scale (VAS), compared with the fentanyl group, the postoperative VAS at 2-hour, 4-hour, 8-hour, 12-hour, 24-hour and 48-hour was decreased in the sufentanil group; b) as for sedation scale, the fentanyl group, the postoperative sedation at 12-hour and 24-hour was lower in the sufentanil group when adopting 0 to 3 points scoring method, but there were no significant differences at other time points; c) as for drug dosage, compared with the fentanyl group, the postoperative drug consumption at 24-hour and 48-hour was less in the sufentanil group; d) as for adverse reaction, the incidence of postoperative nausea, vomiting, dizziness and somnolence in the sufentanil group was lower than those in the fentanyl group. But there was no significant difference in other adverse reactions such as skin itching, limbs numbness and motor disturbance between the two groups; and e) as for the demands of additional analgesic drugs, compared with the fentanyl group, the incidence of demanding additional analgesic drugs was lower in the sufentanil group. Conclusion Compared with fentanyl, sufentanil has better effects of analgesia and sedation for PCEA; Its dosage and incidence of adverse reactions are lower, so sufentanil is safer in clinic.
Abstract： Objective To study thoracic bone remodeling and clinical effects after minimally invasive correctionfor pectus excavatum （PE） in children. Methods A retrospective review was conducted of a prospectively gathereddatabase of 74 child patients who underwent minimally invasive repair of PE at General Hospital of Beijing MilitaryDistrict between Apr. 2009 and Sept. 2010. Of the patients, 63 were males and 11 females; the age was（ 11.90±8.50）years, 11 patients ＜ 10-year-old among them. Under general anesthesia, two incisions were made at the side midaxillaryline, and the introducer created a tunnel at the trans-substernum and shaped the thoracic cavity. The bar was then insertedinto the retrosternum by video-assistant thoracoscopic monitoring. All patients were checked by chest computerizedtomography（CT） scan preoperatively and one week after operation, with three-dimensional reconstruction. The sagittalview was by means of the center line of the body of thoracic vertebrae. The distance between the sternum and the frontaledge of the body of thoracic vertebrae was measured and the return of displacement of the heart was observed. ResultsAll 74 operations were successful; there were no deaths. One bar was used for 66 patients （89.19%）, while two barswere used for the other 8 patients （10.81%）. Comparing the results of pre- with post-correction, for patients youngerthan 10 years（n=11） who had one bar placed, the inferior extremity of the manubrium and midsternum displacedforward to 3.76-22.92 mm. For 11-17 year-old patients（n=55） , anterior displacement of only the middle and lowerpart of the midsternum was 2.08-10.42 mm. There was a significant difference between the two groups in the inferiorextremity of the midsternum displaced（t=14.24, P ＜ 0.05）. For those patients with two bars, the inferior extremity ofthe manubrium and the midsternum were each displaced forward 4.19-15.03 mm at 7 d after operation. At 7 d after operation,the cardiac position in 65 patients（ 87.84%） of the all putted back by CT image. The chest shape of patients who received twobars was better than that of patients who received one bar. After 6-23 months of follow-up, it was pre-operative symptomsdisappeared in the patients, chest shape was satiation. Cardiac position in all patients was completely recovered. ConclusionThe thoracic bones of children with PE after minimally invasive repair have favorable remodeling. Older children requiregreater strength of support of the sternum during correction, but still realize a satisfactory therapeutic effect.
ObjectiveTo investigate the effect of anterior chest wall depression on the cardiac function and the effectiveness of minimally invasive surgery for pectus excavatum by comparing cardiac function and morphology between pre- and post-operation. MethodsBetween August 2009 and December 2010, 102 adult patients with pectus excavatum were treated with minimally invasive surgery, including the primary operation in 95 cases and the reoperation in 7 cases. There were 84 males and 18 females, aged 18-57 years (mean, 23.4 years). The haller index (HI) was 4.59 ± 1.51. Of 102 patients, 59 were classified as pectus excavatum type I and 43 as type II; 42 had clinical symptoms and 19 had the physical sign of heart. The preoperative chest CT examination showed cardiac compression in all patients and heart displacement in 74 patients. The left ventricular ejection fraction (LVEF) was 68.9% ± 6.2%. ResultsThe procedure was successful in all patients, and no death or serious complication occurred. The patients were followed up 12-28 months (mean, 21 months). The clinical symptoms and cardiac physical sign of the patients disappeared after operation. HI was 2.70 ± 0.33 at 12 months after operation, showing significant difference when compared with preoperative HI (t=5.83, P=0.00). According to Nuss’s evaluation method, the results were excellent in 99 patients and good in 3 patients. CT examination showed complete relief of cardiac compression in 101 patients and mild cardiac compression in 1 patient; the heart position was normal at 12 months after operation. Electrocardiogram returned to normal in 4 patients having abnormal electrocardiogram. LVEF was 70.5% ± 4.8% after operation, showing no significant difference when compared with preoperative LVEF (t=1.08, P=0.30). ConclusionThe main effects of pectus excavatum in adults on heart are compression and displacement. Cardiac compression may be relieved efficiently and the patient’s clinical symptoms can be abated by minimally invasive surgery.
Objective To investigate the clinical feasibility and effectiveness of the modified grafted tubularized incised plate urethroplasty (G-TIP), namely “glans G-TIP (GG-TIP) ”, in treatment of hypospadias. Methods A clinical data of 137 children with hypospadias qualified by the selection criteria between January 2021 and June 2023 was retrospectively analyzed. Among them, 75 children were treated with GG-TIP (GG-TIP group) and 62 with G-TIP (G-TIP group). There was no significant difference (P>0.05) between the two groups in terms of age, hypospadias type, penile length, penile head width, penile head height, penile curvature, meatus-apex distance, urethral plate width, and distance from the distal endpoint of navicular groove to the dorsal or ventral midline point of the glans corona, and the difference between the two. The operation time, reconstructed urethral length, distance from meatus to ventral glans corona, postoperative complications, maximum urinary flow rate at 2 weeks after operation, and the hypospadias objective scoring evaluation (HOSE) score at 6 months after operation in the two groups were recorded and analyzed. Results The operation time was significantly shorter in GG-TIP group than in G-TIP group (P<0.05); but there was no significant difference (P>0.05) between the two groups in terms of reconstructed urethral length and distance from meatus to ventral glans corona. All urinary meatus located at the tip of glans with vertical fissure shape. All children in the two groups were followed up 6-35 months (median, 26 months). During follow-up, there were 3 cases of urethral fistula, 2 cases of urethral stricture, and 1 case of glans separation in GG-TIP group, and 3, 3, and 1 cases in the G-TIP group, respectively. There was no significant difference in the incidence of complications between the two groups (P>0.05). The maximum urinary flow rate at 2 weeks and the HOSE score at 6 months after operation were significantly higher in GG-TIP group than in G-TIP group (P<0.05). Conclusion GG-TIP is safe and effective for repairing hypospadias in children. Compared with G-TIP, it has the advantages of relatively simple operation, shortened operation time, significant improvement in urinary flow rate, and better cosmetic results.
ObjectiveTo investigate the effectiveness of penile up transfer method in the treatment of penoscrotal transposition (PST) in children. Methods A clinical data of 46 children with PST admitted between January 2015 and March 2021 and met selective criteria was retrospectively analyzed. The M-shaped scrotal flap method was adopted in 21 cases (group A), and the penile up transfer method was adopted in 25 cases (group B). There was no significant difference in age and PST typing between the two groups (t=0.491, P=0.626; χ2=0.710, P=0.790). The operation time and postoperative complications of the two groups were recorded and compared, and the correction effect of PST was evaluated. Results All operations were successfully completed, and no urethral injury occurred during operation. The operation time was significantly less in group B than in group A [(70.36±9.76) minutes vs. (96.62±13.18) minutes; t=7.553, P=0.000]. All children were followed up 6-33 months (mean, 13.2 months). There were 5 cases (23.8%) of skin necrosis and 6 cases (28.6%) of scar hyperplasia in group A, and 1 case (4.0%) of skin necrosis and 1 case (4.0%) of scar hyperplasia in group B. The incidence of complication was significantly lower in group B than in group A (χ2=3.949, P=0.047; χ2=5.341, P=0.021). In the evaluation of PST correction at 6 months after operation, there were 15 cases of complete correction and 6 cases of incomplete correction in group A, 24 cases of complete correction and 1 case of incomplete correction in group B, and the difference was significant (χ2=5.341, P=0.021). Conclusion The penis up transfer method is not only easy to correct PST, but also can correct scrotal separation at the same time, with fewer postoperative complications and satisfactory correction effect of penile scrotal appearance.
Objective To enhance the understanding of nonfibrotic hypersensitivity pneumonitis (nfHP) by summarizing the clinical characteristics of 32 cases of nfHP. Methods The data of 32 cases with nfHP was collected and analyzed. They were diagnosed in Beijing Friendship Hospital, Capital Medical University from Jan 1st, 2017 to Oct 31, 2021. Results The median age of the nfHP patients was 54 years, among whom 75.0% were females. The cases developed in a majority of avian exposure (22 cases, 68.8%). The main symptoms were dyspnea/shortness of breath (28 cases, 87.5%), cough (25 cases, 78.1%）and sputum production (21 cases, 65.6%). High-resolution CT (HRCT) showed diffuse ground glass opacification (25 cases, 78.1%), centrilobular ground glass nodules (20 cases, 62.5%) and air trapping (9 cases, 28.1%). Bronchoalveolar lavage fluid (BALF) featured an increase of proportion of lymphocytes (>20%, 90.6% and >40%, 50%), and a decrease of CD4+/CD8+ T cell ratio (<1.2, 65.6% and <0.8, 40.6%). Most of the cases had reduced diffusion capacity for carbon monoxide (16 cases out of 26 cases, 61.5%) and decreased total lung capacity (13 cases out of 26 cases, 50%). Few cases showed obstructive ventilatory function (6 cases out of 26 cases, 23.1%). Most cases (22 cases, 68.8%) of nfHP showed an excellent survival with short-term corticosteroid treatment. Few cases (5 cases, 15.6%) experienced spontaneous remission after antigen avoidance. Conclusions The diagnosis of nfHP includes identifying antigenic exposures, featured chest HRCT and lymocytosis in BALF. nfHP patients showed an excellent survival with short-term corticosteroid treatment as well as antigen avoidance.
ObjectiveTo investigate the changes and clinical significance of cardiac structure and function evaluation by cardiac magnetic resonance imaging (CMR) for patients with pectus excavatum deformity at preoperation. MethodsWe retrospectively analyzed 54 patients (24 children and 30 adults) who underwent pectus excavatum surgery from June 2012 to June 2014. There were 48 males and 6 females at age of 7-33 (19.08±5.17) years. All the patients underwent CMR using 1.5 Tesla scanner for evaluation of compressing and displacement of the heart. The major and minor dimensions of right ventricle were measured. The right ventricle end-diastole volume (RVEDV), right ventricle end-systolic volume (RVESV), and right ventricle ejection fraction (RVEF) were also recorded and analyzed. ResultsThe heart compression and displacement occurred in 83.3% of the children group and 90.0% of the adults group. The extent of heart displacement in the adults was more serious than that in the children (76.86%±13.30% vs. 67.99%±8.15%, P<0.05). The structure of right ventricle were striking distorted because right atrum or right ventricule below valve ring was compressed locally, with the major dimension of right ventricle obviously increased, and the minor dimension of right ventricle obviously decreased. The indices of right ventricle major dimension and right ventricle minor dimension were 61.14±0.44 mm/m2 and 14.82±2.52 mm/m2 in the children, 49.54±15.40 mm/m2 and 18.90 ±3.14 mm/m2 in the adults. The RVEDV and RVESV were significantly higher in the adults than those in the children (139.09±29.08 ml vs. 121.50±31.27 ml; 73.61±16.05 ml vs. 64.92±19.28 ml; P<0.05). RVEF was similar between the children and the adults (45.29%±4.14% vs. 46.30±6.09%). The patients' symptoms disappeared after correction of pectus excavatum. ConclusionCMR is an useful method for evaluating right ventricular structure and functions in patients with cardiac compression and distortion by pectus excavatum before operation, which can bring strong indications for pectus excavatum repair surgery.
Objective To compare the in-hospital and midterm outcomes after simultaneous hybrid coronary revascularization (HCR) with off-pump coronary artery bypass grafting (OPCAB) in diabetic patients with multivessel coronary artery disease. Methods One hundred thirty-two diabetic patients with multivessel coronary artery disease underwent one-stop HCR at Fuwai Hospital from January 2010 to January 2015. These patients were 1∶2 matched with those who underwent OPCAB using propensity score matching. Results Simultaneous HCR had less chest tube drainage (618 (420, 811) ml vs. 969 (711, 1 213)ml, P<0.001), lower transfusion rate (19.7%vs. 34.1%, P=0.026), shorter mechanical ventilation time (11.6 (8.2, 14.8) h vs. 16.0 (12.1, 18.7) h, P<0.001), and shorter stay in intensive care unit (21.5 (18.8, 42.0) hvs. 44.6 (23.7, 70.1) h, P<0.001) than OPCAB. During over median 40 months follow-up, simultaneous HCR offered similar major adverse cardiac or cerebrovascular events (MACCE) rate (6.8%vs 9.0%, P=0.826), but lower stroke rate (0% vs 3.0%, P=0.029), compared with OPCAB. Conclusion For selected patients with diabetes, simultaneous HCR provides a safe and effective revascularization alternative. It decreases perioperative invasiveness and incurred similar and favorable midterm outcomes with OPCAB.
