ABSTRACT
Objective:To compare the effects between video-assisted thoracoscopic surgery (VATS) and conventional surgery in internal fixation of multiple rib fractures.Methods:Patients with multiple rib fractures, who were admitted to Emergency Center of Shenzhen People's Hospital from June 2010 to May 2020, were included. Patients were divided into the VATS group (incision positioning with VATS) and the conventional group (incisionpositioning with CT scan). The primary outcome measures was the risk of complications, and the secondary outcome measures included postoperative pain, incision length, operation time, and mechanical ventilation rate. Continuous and categorical variables were compared using LSD- t test and Chi-square test. Repeated measures analysis of variance was performed to assess the trend of postoperative pain over time. A logistic regression analysis was used to explore the association of VATS with postoperative complications. Results:A total of 221 patients, including 128 patients in the VATS group and 93 patitents in the conventional group, were enrolled. Baseline characteristics were identical between the two groups ( P>0.05). In the VATS group, the length of incision, intraoperative blood loss, operation time, mechanical ventilation rate after operation, ventilation time, thoracic tube indwelling time, ICU and total length of stay, and medical costs were better than those in the conventional group (all P<0.05). Repeated measures analysis of variance showed that pain relief was faster and more profoundly in the VATS group than in the conventional group ( F=3 517.808, P<0.01). Logistic regression analysis indicated that VATS was an independent protective factor for reducing postoperative complications ( OR=0.225, 95% CI:0.121-0.416, P<0.01). Conclusions:During internal fixation of multiple rib fractures, VATS is an effective approach to reduce postoperative pain and complications. Moreover, video-assisted technique is associated with a rapid recovery for patients, resulting in shorter length of hospital stay and less medical costs.
ABSTRACT
Objective To investigate the effect of limitation in flow of people on medical care quality in emergency resuscitation room (ERR).Methods This study was retrospectively performed to compare emergency medical quality before and after (October to December,2015 vs.February to April,2016) limitation of flow of people in ERR.Variables included noise level,occupational exposure,adverse event,hospital-acquired infection,length of stay (LOS) in ERR,mortality rate,return of spontaneous circulation (ROSC) rate after cardiopulmonary resuscitation (CPR),the rate of unexpected return to ERR,door to drug and door to balloon time for patients with ST-segment elevated myocardial infarction (STEMI),patients' and emergency personnels' satisfaction level.The data were analyzed with t-test,chi-square test or Poisson Z test where appropriate.Results There were 5 031 and 5 097 patients respectively admitted in ERR before and after limitation of flow of people.Patients' main diagnoses and severity of illness between the two periods had no significantly difference (P＞0.05).After the limitation of flow of people,the noise level in ERR was lowered (P＜0.01),the numbers of occupational exposure events (14 cases vs.4 cases,Z=2.357,P=0.018) and adverse events (18 cases vs.5 cases,Z=2.711,P=0.007) were decreased,the rate of hospital-acquired infection was reduced (1.1％ vs.0.5％,x2=8.111,P=0.004),the LOS in ERR was shortened [(6.3±0.8) h vs.(4.6±0.6) h,t=121.083,P＜0.01],the door to balloon time for STEMI patients was also decreased [(91.2±12.8) min vs.(89.3±8.0) min,t=2.486,P=0.013].Moreover,patients' and emergency personnels' satisfaction level were elevated.No significant difference was observed in mortality rate,ROSC rate,rate of unexpected return to ERR and door to drug time for STEMI patients.Conclusions The limitation of flow of people in ERR can lower the noise level,reduce emergency personnels' working pressure,improve their working efficiency,avoid medical errors,elevate patients' and emergency personnels' satisfaction level.
ABSTRACT
Objective To compare the efficacy and safety of nicardipine versus urapidil in blood pressure (BP) management during the acute phase of intracerebral hemorrhage (ICH).Methods ICH patients admitted in Emergency Intensive Care Unit of Shenzhen People's Hospital from March,2013 through March,2016 were retrospectively studied.Patients were enrolled as nicardipine group or urapidil group depending on the initial antihypertensive drug given at admission.The differences in rate of patients reached the goal BP within the first 24 h,time required for getting goal BP,blood pressure variability (BPV),rebleeding or hematoma expansion during the first 24 h,cerebral state index (CSI) within 7 days and 28-day mortality were compared between the two groups.The differences in adverse events including bradycardia,tachycardia and hypotension were also compared between two groups.An independent t test and x2 test were performed to compare different variables.An analysis of variance of repeated measurement was performed to compare CSI within 7 days between two groups.Results Seventy-seven patients were included with 42 in nicardipine group and 55 in urapidil group.Rate of patients getting goal BP in nicardipine group was (94±5)％ and (86±11)％ in urapidil group (P＜0.01).Time required to get goal BP was (35 ± 28) min in nicardipine group and (52 ± 37) min in urapidil group (P =0.02).BPV was (11.23 ± 2.38) in nicardipine group and (13.16 ± 3.15) in urapidil group (P =0.003).Rebleeding or hematoma expansion rate during the first 24 h and 28-day mortality rate were comparable between the two groups (P ＞ 0.05).Through analysis of variance of repeated measurement,CSI in nicardipine group improves more rapidly than that in urapidil group (F =1 581.115,P =0.000).Hypotension,bradycardia and tachycardia were also comparable between groups (P ＞ 0.05).Conclusion Compared with urapidil,nicardipine produces effect more rapidly with more stable BP and higher rate of patients with ICH getting goal BP.Moreover,the application of nicardipine may be better to improve the CSI of ICH patients.
ABSTRACT
Objective To study the effects of large dose anisodamine (654-2) combined with ulinastain on severe acute pancreatitis (SAP).Methods 100 healthy adult SD rats which were fasted 12 hours before experiment and were allowed drinking water freely,were divided to 5 groups randomly (random number):normal control group,SAPgroup,SAP + Ulinastain group,SAP + Anisodamine group,SAP +Ulinastain + Anisodamine,there were 20 rats in every group.To observe the levels of diastase,phospholipase A2 (PLA2) and endotoxin and pathology of rats in every group.Another cohort of 60 SD rats were divided into 3 groups:SAP group,SAP + Ulinastain group,SAP + Ulinastain + large dose Anisodamine group,survival periods were observed.Results The levels of diastase,PLA2 and endotoxin in SAP rats were higher than those in 3 SAP with treatment groups (P ＜ 0.05).The histopathological changes were most severe in SAP group.All of 3 markers in 3 SAP with treatment groups decreased obviously,and anisodamine alone was effective to treat SAP,but the effect of UTI + 654-2 was better than UTI or 654-2 alone,and histopathological changes were mild in this group treated with UTI + 654-2.Conclusions Anisodamine could effectively relax the Oddi sphincter thereby decreasing the hydrostatic pressure inside the bile duct and pancreatic duct.Ulinastain is a kind of proteinase inhibitor suppressing many kinds of enzymes and in tern to stabilize lysosomal membrane and inhibit the release of lysosomal enzyme.Combination of the large dose Anisodamine with Ulinastain could inhibit the overexpression of inflammationarv factors in SAP,thereby lessening the severity of viscera injury.
ABSTRACT
Objective To investigate the effect of Tetramethylpyrazine (extracted from Chinese herbal medicine Ligusticum wallichii) employed in the early stage of severe brain injury on the restoration of brain function in coma patients monitored with digitized cerebral state monitor and clinical signs.Methods A total of 364 patients were referred to us from Emergency Department and Neurosurgery Department,Shenzhen People's Hospital from January 2006 through May 2012.The scores of patients'GlasgowPittsburgh coma scales were between 7-20 as brain injury happened within 24 h and survived more than two weeks.All patients were randomly (random number) divided into two groups:Tetramethylpyrazine group (n =186) and control group (n =178).The patients of control group received routine treatment,and the patients of Tetramethylpyrazine group were treated with Tetramethylpyrazine in addition to routine treatment in early stage.The patients of two groups were assessed with cerebral state indexes (CSI) and GlasgowPittsburgh coma scales before treatment and 3,7,14 days after treatment.Statistical comparisons between groups were analyzed by using repeated measure design analysis of variance.Results A repeated measures design analysis of variance indicated that the CSI and clinical signs (Glasgow-Pittsburgh coma scale) were improved significantly in Tetramethylpyrazine group than those in the control group at 3,7,14 days after treatment (P =0.024).Conclusions Tetramethylpyrazine can protect brain function and improve clinical signs in patients with severe brain injury in the early stage.
