Objective To discuss the relationship between recovery of anatomical integrity and functional outcome in elderly patients with distal radius fractures by comparing the effects of open reduction and closed reduction. Methods The cl inical data were retrospectively analyzed from 78 elderly patients with distal radius fractures treating with nonoperation andoperation from February 2005 to March 2009. Thirty-seven patients underwent closed reduction and spl intlet fixation or cast appl ication (non-operation group), and forty-one patients underwent open reduction and internal fixation (operation group). In non-operation group, there were 15 males and 22 females with an average age of 73 years (60-83 years). According to the AO classification system for fracture, there were 8 cases of type A2, 7 cases of type A3, 7 cases of type B1, 4 cases of type B2, 2 cases of type B3, 4 cases of type C1, 2 cases of type C2, and 3 cases of type C3. The time from injury to admission was between 30 minutes and 3 days with a mean time of 1 day. In operation group, there were 18 males and 23 females with an average age of 71 years (62-80 years). According to the AO classification system for fracture, there were 5 cases of type A2, 7 cases of type A3, 7 cases of type B1, 6 cases of type B2, 3 cases of type B3, 4 cases of type C1, 5 cases of type C2, and 4 cases of type C3. The time from injury to admission was between 30 minutes and 7 days with a mean time of 1 day. There were no significant differences (P gt; 0.05) in sex, age, disease course and fracture classification between two groups. Results All incisions obtained heal ing by first intention after operation in operation group. All patients were followed up for 9-36 months (20 months on average). Fracture heal ing was achieved within 8 to 15 weeks, with an average of 11 weeks. There were no significant differences (P gt; 0.05) in fracture heal ing time between non-operation group [(10.8 ± 2.0) weeks] and operation group [(11.7 ± 2.5) weeks]. At last follow-up, thepalmar tilt angle was (5.6 ± 2.0)° and (8.6 ± 3.0)°, the radial incl ination angle was (19.1 ± 4.9)° and (21.8 ± 2.0)°, and the radial length was (8.3 ± 1.3) mm and (10.4 ± 1.4) mm in non-operation group and operation group, respectively; showing significant differences (P lt; 0.05) between two groups. According to the Gartland-Werley score, the results were excellent in 9 cases, good in 21 cases, fair in 5 cases, and poor in 2 cases in non-operation group, the excellent and good rate was 81.1%; in operation group, the results were excellent in 13 cases, good in 25 cases, fair in 2 cases, and poor in 1 case, the excellent and good rate was 92.7%, showing no significant difference (P gt; 0.05) between two groups. There were no significant differences (P gt; 0.05) in flexion and extension activity of wrist, radioulnar partial activity, pronation-supination activity, grip and pinch strength between two groups. Conclusion Open reduction and closed reduction can achieve satisfactory functional outcomes, but closed reduction was inferior to open reduction in anatomic reduction for treating distal radius fractures in elderly patients.
Objective To evaluate the influence of dexmedetomidine on the stress of elderly patients with cardiovascular risk undergoing gastrointestinal laparoscopic surgery. Methods From August 2014 to December 2015, 210 patients undergoing elective laparoscopic gastrointestinal operations were randomly divided into three groups, including the low concentration group (group D1), the high concentration group (group D2), and the control group (group C), with 70 cases in each group. The patients in group D1 and group D2 were injected with dexmedetomidine (0.4 and 0.8 μg/kg respectively) by infusion pump before anesthesia induction, and were continuously pumped with dexmedetomidine [0.4 and 0.8 μg/(kg·h) respectively] until the end of the surgery. Meanwhile, the patients in group C were injected with normal saline of the equal volumes. The heart rate and mean arterial pressure (MAP) was recorded before anesthesia, after endotracheal intubation and extubation. Myocardial ischemia and cardiovascular adverse events thatneeded to be handled were recorded. The concentrations of dopamine, adrenaline (AD) and noradrenaline (NE) were monitored at 15:00 one day before surgery (Ty), one hour after the beginning of surgery (T0), and at 15:00 of the 1st, 2nd, and 3rd day after surgery (T1, T2, T3). Results A total of 178 patients completed the study and were enrolled in this study, including 60 cases in group D1 and 59 cases in group D2 and C respectively. In group D1 and D2, the heart rates after intubation [(80.4±9.6), (68.2±10.5) times/minutes], extubation [(70.1±6.2), (69.7±7.8) times/minutes] and MAP after extubation [(100.2±12.0), (98.0±13.1) mm Hg (1 mm Hg=0.133 kPa)] were lower than those in group C [(98.4±10.5) and (95.2±7.3) times/minutes; (121.8±10.5) mm Hg], and the differences were significant (P<0.05). The bradycardia and hypotension in group D2 (27.12%, 22.03%) was significantly higher than those in group C (3.39%, 8.47%). Hypertension in group D1 and D2 (5.00%, 1.69%) was significantly lower than that in group C (37.29%), and the differences were significant (P<0.05). Compared with the base value at Ty in the three groups, the concentration of dopamine at T0-T3 in group C, at T0-T1 in group D1, and at T0 in group D2 increased significantly (P<0.05); the AD at T0-T3 in group C, at T0-T2 in group D1, and at T0-T1 in group D2 increased significantly (P<0.05); the NE at T0-T2 in group C, and at T1 in group D1 increased significantly (P<0.05). Compared with group C at the same time, the DA at T3 in group D1 and at T1-T3 in group D2, the AD at T2-T3 in group D1 and at T0-T3 in group D2, the NE at T0-T1 in group D1 and T0-T3 in group D2, decreased significantly (P<0.05). Conclusions Dexmedetomidine can effectively restrain the changes of hemodynamics and catecholamine induced by perioperative stress responses in a dose-dependent manner. During the surgery of elderly patients with cardiovascular risk, the concentration of dexmedetomidine should be controlled moderately to gain the optimal effect.
Objective To investigate the effective dose of remimazolam benzenesulfonate to suppress cardiovascular responses to laryngeal mask placement in elderly patients. Methods Elderly patients undergoing laryngeal mask anesthesia between March and June 2023 were selected. Combined with sulfentanil 0.2 μg/kg, remimazolam was used as induction hypnotic. The first patient was given remizolam benzenesulfonate 0.16 mg/kg infused by pump for 1 min. The dose of remimazolam for the next patient was determined by the biased coin up-and-down method based on the patient’s response to the laryngeal mask placement. The score of Modified Observer’s Assessment of Alert/Sedation, vital signs and anesthesia depth index (AI) were recorded during induction. Probit analysis was used to calculate the half effective dose (ED50), 95% effective dose (ED95) and half effective AI (AI50). According to the statistical requirements, at least 45 negative patients were required. Results A total of 53 elderly patients were enrolled in the study until the end of the trial. The ED50 and ED95 of remimazolam benzenesulfonate for inhibiting cardiovascular responses to laryngeal mask insertion were 0.154 mg/kg [95% confidence interval (CI) (0.034, 0.170) mg/kg] and 0.207 mg/kg [95%CI (0.190, 0.614) mg/kg], respectively. AI decreased during induction, with an AI50 of 64.119 [95%CI (60.609, 69.984)]. Conclusion When combined with 0.2 μg/kg sufentanil, infusing 0.2 mg/kg remimazolam benzenesulfonate for 1 min is effective and safe for laryngeal mask anesthesia induction in elderly patients.
ObjectiveTo systematically review the postoperative infection-related complications between cemented and cementless hemiarthroplasty in elderly patients with femoral neck fracture.MethodsCochrane Library, PubMed, Embase, China Biology Medicine Database, Chongqing VIP China Science and Technology Journal Database, China National Knowledge Infrastructure, and Wanfang Database were searched to collect randomized controlled trials of postoperative infection-related complications between cemented and cementless hemiarthroplasty in elderly patients with femoral neck fracture from inception to January 2018. A systematic review was performed to compare the postoperative deep infection, superficial wound infection, pneumonia infection, and urinary tract infection between cemented and cementless hemiarthroplasty. Analyses were conducted using Review Manager version 5.2.0 software.ResultsA total of 11 studies were included in the Meta-analysis, including 1 533 patients. There was no significant difference in the incidence of deep infection [odds ratio (OR)=1.62, 95% confidence interval (CI) (0.66, 3.94), P=0.29], superficial wound infection [OR=1.17, 95%CI (0.56, 2.47), P=0.68], pneumonia infection [OR=0.73, 95%CI (0.47, 1.13), P=0.16], or urinary tract infection [OR=1.10, 95%CI (0.65, 1.86), P=0.73] between the two groups.ConclusionWhen selecting a fixation method for hemiarthroplasty to treat eldly patients with femoral neck fracture, infection-related postoperative complications are not the determinant factor to consider.
Objective To investigate the impact of nutritional risk on unplanned readmissions in elderly patients with chronic obstructive pulmonary disease (COPD), to provide evidence for clinical nutrition support intervention. Methods Elderly patients with COPD meeting the inclusive criteria and admitted between June 2014 and May 2015 were recruited and investigated with nutritional risk screening 2002 (NRS 2002) and unplanned readmission scale. Meanwhile, the patients’ body height and body weight were measured for calculating body mass index (BMI). Results The average score of nutritional risk screening of the elderly COPD patients was 4.65±1.33. There were 456 (40.07%) patients who had no nutritional risk and 682 (59.93%) patients who had nutritional risk. There were 47 (4.13%) patients with unplanned readmissions within 15 days, 155 (13.62%) patients within 30 days, 265 (23.28%) patients within 60 days, 336 (29.53%) patients within 180 days, and 705 (61.95%) patients within one year. The patients with nutritional risk had significantly higher possibilities of unplanned readmissions within 60 days, 180 days and one year than the patients with no nutritional risk (all P<0.05). The nutritional risk, age and severity of disease influenced unplanned readmissions of the elderly patients with COPD (all P<0.05). Conclusions There is a close correlation between nutritional risk and unplanned readmissions in elderly patients with COPD. Doctors and nurses should take some measures to reduce the nutritional risk so as to decrease the unplanned readmissions to some degree.
ObjectiveTo evaluate the nursing health education for elderly patients with restoration of complete denture by meta-analysis.MethodsWe searched the Joanna Briggs Institute Library, The Cochrane Library, PubMed, CBM, CNKI and WanFang Data from inception to March 2016 to collect RCTs about nursing health education for elderly patients with restoration of complete denture. Two researchers independently screened literatures, extracted data and assessed the risk of bias of included studies. Then meta-analysis was performed by RevMan 5.2 software.ResultsThirteen RCTs including 1 086 elderly patients who underwent restoration of complete denture were included, involving 575 cases in nursing health education group and 511 in normal nursing group. The results of meta-analysis showed that: the total effective rate (RR=1.26, 95%CI 1.12 to 1.41, P<0.000 1), the degree of mastering related knowledge (RR=1.30, 95%CI 1.16 to 1.45, P<0.000 01) and satisfaction of complete denture (voice: MD=0.21, 95%CI 0.09 to 0.32, P=0.000 4; retention: MD=0.18, 95%CI 0.06 to 0.30, P=0.003; comfort: MD=0.43, 95%CI 0.22 to 0.63, P<0.000 1) in health education group were superior to the control group.ConclusionNursing health education is effective for elderly patients with restoration of complete denture. Due to the limited quantity and quality of include studies, the above conclusions are still needed to be verified by more studies.
ObjectiveTo evaluate whether laparoscopic repair for perforated peptic ulcer o ers elderly patients an improved outcome compared with conventional open surgery. MethodsFrom May 2008 to December 2013, clinical data of 163 elderly patients ( ≥ 60 years) who underwent laparoscopic or open repair of perforated peptic ulcer disease were analyzed retrospectively in our hospital. Ninety-one patients received laparoscopic repair and 72 received conventional open repair. The primary end points that were evaluated were total operative time, searching time, nasogastric tube utilization, intravenous fluid requirement, total time of abdominal drainage and urinary catheter usage, time taken to return to normal gastrointestinal motility, percentage of intravenous/intramuscular opiate use, off-bed time, and total in-patient hospital stay. The second end points were morbidity. ResultsThere was a significant diTherence in total operative time in patients who had undergone laparoscopic repair and open repair [(67.9±3.6) minutes vs. (97.8±5.2) minutes]. There was a significant decrease in the time that the nasogastric tube (2.1 days vs. 3.1 days), urinary catheter (2.3 days vs. 3.7 days) and abdominal drain (2.2 days vs. 3.8 days) were required during the postoperative period. Patients who had undergone laparoscopic repair also required less intravenous fluids (2.4 days vs. 4.1 days) and returned to normal gastrointestinal motility [(32.1±1.5) hours vs. (58.4±4.8) hours] and off-bed time significantly earlier than those who had undergone open repair (2.1 days vs. 3.5 days). There was significantly less requirement for intravenous/intramuscular opiate analgesia in patients who had undergone laparoscopic repair (4.7% vs. 45.6%). In addition, patients who had undergone laparoscopic repair required a shorter in-patient hospital stay (4.1 days vs. 5.3 days). Moreover, morbidity of laparoscopic repair was much lower than open repair (3.3% vs. 16.7%). ConclusionLaparoscopic repair is a viable and safe surgical option for elderly patients with perforated peptic ulcer disease and should be considered for all patients.
ObjectiveVideo electroencephalography (VEEG) monitoring for health education of elderly patients based on a process-based communication model, and explore the impact of this model on the success rate, negative emotions, nursing satisfaction, and active cooperation rate of such patients.MethodsFrom September 2017 to September 2019, 118 patients with suspected epilepsy, encephalitis and other diseases who required VEEG monitoring in Suining Central Hospital were selected for this study (patients aged 61 to 73 years; 54 males and 64 females). Patients were divided into 2 groups using a random number table method, 59 patients in each group.A group received routine nursing, and B group received health education based on the process communication model. The monitoring success rate, negative emotion, active cooperation rate, and nursing satisfaction were compared between the two groups.ResultsThe total effective rate in the B group was 86.44%, which was significantly higher than 76.27% in the A group (P<0.05). After nursing intervention, the scores of anxiety and depression in the two groups were significantly decreased, but the decline was greater in the B group (P<0.05). The active cooperation rate and nursing satisfaction of the B group were significantly higher than those of the A group (P<0.05).ConclusionCompared with conventional nursing, health education based on process communication mode can significantly improve the success rate of VEEG monitoring in elderly patients, alleviate the negative emotions of patients, improve the active cooperation rate and nursing satisfaction.
Objective To explore the diagnosis and treatment strategies for elderly patients with ground-glass opacity (GGO). MethodsThe imaging features and postoperative pathological findings of the elderly patients with pulmonary GGO receiving surgery in our hospital from 2017 to 2019 were retrospectively analyzed. The patients were divided into an elderly patient group and a non-elderly patient group based on their age. Results Finally 575 patients were included in the study. There were 281 elderly patients, including 83 males and 198 females, with an average age of (67.0±5.3) years. There were 294 non-elderly patients, including 88 males and 206 females, with an average age of (49.1±7.3) years. Compared with the non-elderly patients, elderly GGO patients showed the following distinct clinical features: long observation time for lesions (P=0.001), high proportion of rough edges of GGO (P<0.001), significant pleural signs (P＜0.001) and bronchial signs (P＜0.001), and high proportion of type Ⅱ-Ⅳ GGO (P<0.001), lobectomy type (P=0.013), and invasive lesions reported in postoperative pathology (P<0.001). There was no statistical difference in the average hospital stay between the two groups (P=0.106). Multivariate logistic regression analysis showed that GGO diameter and GGO type were the main factors affecting the operation. Observation time, GGO diameter, GGO type and pleural signs were the main influencing factors for postoperative pathological infiltrative lesions. The cut-off value of GGO diameter in predicting infiltrating lesions was 10.5 mm in the elderly patients group. Conclusion The size and type of GGO are important factors in predicting invasive lesions and selecting surgical methods. Elderly patients with radiographic manifestations of type Ⅱ-Ⅳ GGO lesions with a diameter greater than 10.5 mm should be closely followed up.
ObjectiveTo systematically review the influence of dexmedetomidine on early postoperative cognitive dysfunction (POCD) and serum inflammatory factors in elderly patients.MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, CNKI, WanFang Data and VIP databases from inception to April 2017, to collect randomized controlled trials (RCTs) about dexmedetomidine for early POCD in elderly patients. Two reviewers independently screened literature, extracted data, and assessed the risk of bias of included studies. Then, meta-analysis was performed by RevMan 5.3 software.ResultsA total of 23 RCTs, including 2 026 patients were enrolled. The results of meta-analysis showed that, the incidence of POCD in the dexmedetomidine group was lower than that in the control group (the first day: RR=0.40, 95%CI 0.30 to 0.53, P<0.000 01; the third day: RR=0.33, 95%CI 0.23 to 0.48,P<0.000 01; the seventh day: RR=0.42, 95%CI 0.22 to 0.78,P=0.006). Meanwhile, compared with the control group, the dexmedetomidine group significantly decreased the serum levels of TNF-α (immediately after operation: MD=–5.43, 95%CI –7.44 to –3.42, P<0.000 01; 1 h after operation: MD=–4.64, 95%CI –6.92 to –2.36,P<0.000 1; 24 h after operation: MD=–3.27, 95%CI –4.92 to –1.63,P<0.000 1) and IL-6 (immediately after operation: MD=–30.69, 95%CI –41.39 to –20.00,P<0.000 01; 1h after operation: MD=–20.84, 95%CI –28.87 to –12.80,P<0.000 01; 24 h after operation: MD=–13.42, 95%CI –19.90 to –6.94,P<0.000 1).ConclusionCurrent evidence indicates that dexmedetomidine could relief early POCD in elderly patients, in which the reduction of serum inflammatory factors alleviate inflammation response may play a vital role. Due to the limited quality and quantity of included studies, more high quality RCTs are required to verify the above conclusion.
