Handgrip Strength Predicts Persistent Walking Recovery After Hip Fracture Surgery

Background

In older people, hip fractures often lead to disability and death. We evaluated handgrip strength, an objective measure of physical function for bedridden patients, as a predictor of walking recovery in the year after fracture surgery.

Methods

This multicenter prospective cohort study included 504 patients, aged 70 years or more, who were admitted to the hospital for hip fracture surgery and were formerly able to walk independently. A multidimensional geriatric evaluation that included a physical examination, Short Portable Mental Status Questionnaire, Geriatric Depression Scale, Charlson Index, Basic Activities of Daily Living, and grip strength was administered at the time of admission. Follow-ups were performed every 3 months for 1 year after surgery to assess functional status and survival. The walking recovery probability was evaluated using multivariable logistic regression models.

Results

The mean age of the participants was 85.3 ± 5.5 years, and 76.1% of the participants were women. The mean grip strength was greater in men (β: 6.6 ± 0.62, P < .001) and was directly related to the Short Portable Mental Status Questionnaire results (P < .001), Basic Activities of Daily Living results (P < .001), serum vitamin D levels (P = .03), and time before surgery (P < .001), whereas it was inversely related to age (P < .001), Geriatric Depression Scale score (P < .001), and Charlson Index (P < .001). After adjusting for confounders, the grip strength was directly associated with the probability of both incident and persistent walking recovery (odds ratio highest tertile vs lowest tertile, 2.84, confidence interval, 1.76-4.59 and 2.79, confidence interval, 1.35-5.79, respectively).

Conclusions

In older patients with hip fractures, early grip strength evaluation might provide important prognostic information regarding the patient's future functional trajectory.     

Predictors of Graft Patency 3 Years After Coronary Artery Bypass Graft Surgery

Objectives. The purpose of this analysis was to define the factors that predict 3-year graft patency.

Background. The success of coronary artery bypass graft surgery (CABG) is dependent on vein graft patency after the operation. It has been well established by a series of Department of Veterans Affairs Cooperative Trials that aspirin (325 mg daily) improves saphenous vein graft patency early (7 to 10 days) and at 1 year, but not at 3 years after CABG. This analysis, based on one of these trials, defined factors that predict 3-year graft patency.

Methods. This analysis consisted of 266 patients, with 656 grafts that were patent 7 to 10 days after the operation, who underwent 3-year catheterization. To determine which patient-specific and/or graft-specific factors, or both, predict graft occlusion, a multivariate logistic regression analysis in terms of latent variables was used. It yielded a model that also took into account possible intraclass correlations.

Results. For a vein graft that was patent at 7 to 10 days after the operation, the positive predictors, according to univariate analysis, for that graft being patent at 3 years were cross-clamp time ≤80 min (p < 0.001), vein preservation solution temperature ≤5°C (p = 0.009), bypass time ≤2 h (p = 0.042), number of proximal anastomoses ≤2 (p = 0.018), operation time ≤5 h (p = 0.044) and continuous versus intermittent cross-clamp technique (p = 0.024). There was also a trend with regard to recipient artery diameter >1.5 mm (p = 0.063), serum cholesterol ≤225 mg/dl (p = 0.084) and single versus sequential or Y vein graft (p = 0.060). Factors not predictive of 3-year patency were age, race, smoking history, high density lipoprotein cholesterol, vein source (thigh vs. calf), coronary artery grafted and aspirin treatment. Of all the predictors obtained in the univariate analysis, the only variables that were sufficient to yield a good model within the multivariate analysis were solution temperature (p = 0.004), serum cholesterol (p = 0.024), number of proximal anastomoses (p = 0.032) and recipient artery diameter (p = 0.034).

Conclusions. For a patient with patent vein grafts 7 to 10 days after the operation, predictors of 3-year graft patency are more closely related to operative techniques and underlying disease and not to aspirin treatment.

Da-Cheng-Qi-Tang Promotes the Recovery of Gastrointestinal Motility After Abdominal Surgery in Humans

In order to examine the effects of Da-Cheng-Qi-Tang (DCQT) on gastrointestinal motility functions after abdominal surgery in humans, 33 patients with abdominal surgeries and 36 patients with cholecystectomies were divided into the DCQT and the control groups at random. Electrogastrography (EGG) and gastroduodenojejunal manometry was performed and the levels of plasma motilin were measured by radioimmunoassay. The results were as follows: (1) on the day of surgery, the ratio of EGG normal frequency in the DCQT group was higher than in the control group (P=0.0016); (2) the power of EGG in the DCQT group was higher than in the control group on the second and third days after surgeries (P=0.0011 and P=0.0215, respectively); (3) the percentage of normal bowel peristalsis was significantly higher in the DCQT group than in the control group (P<0.01); and (4) in the DCQT group, the plasma motilin level reached its peak earlier than in the control group. Our results suggest that DCQT can increase plasma motilin, enhance gastrointestinal motility, improve gastric dysrythmia, and reduce gastroparesis after abdominal surgery.     

Quality of Life and Chronic Pain Four Years After Gastrointestinal Surgery

Purpose Little is known about the prevalence of chronic postsurgical pain after gastrointestinal surgery. This study was designed to assess the prevalence of chronic pain andquality of life in a cohort of patients who underwent surgery for benign and malignant gastrointestinal disease. Methods A prospective cohort design was used to assess quality of life and morbidity at four years postoperatively in435 patients who had upper, hepatopancreaticobiliary, small-bowel, and/or colorectal anastomotic surgery in 1999 at one regional center in Northeast Scotland. Chronic pain and quality of life were assessed by postal survey using the European Organization for Research and Treatment of Cancer Quality of Life-C30 questionnaire and McGill Pain Questionnaire. Results Of the 435 patients recruited in 1999, 135 (31 percent) had died by censor date in 2003. There was a 74 percent (n = 202) response rate from surviving patients eligible for follow-up. Prevalence of chronic pain at four years postoperatively was 18 percent (95 percent confidence interval, 13–23 percent). Pain was predominantly neuropathic in character; a subgroup reported moderate-to-severe pain. Risk factors for chronic postsurgical pain included female gender, younger age, and surgery for benign disease. Compared with those who were pain-free at follow-up, patients with chronic pain had poorer functioning, poorer global quality of life, and more severe symptoms, independent of age, gender, and cancer status. Conclusions The prevalence of chronic pain after laparotomy for gastrointestinal malignancy and nonmalignant conditions at four years after surgery was 18 percent. These patients had significantly poorer quality of life scores independent of age, gender, and cancer status. Supported by the Departments of Surgery and Public Health at the University of Aberdeen.

Successful Voiding After Trial Without Catheter Is Not Synonymous With Recovery of Bladder Function After Colorectal Surgery

Purpose The need for monitoring postoperative urine output and the possibility of lower urinary tract dysfunction following colorectal surgery necessitates temporary urinary drainage. Current practice assumes recovery of lower urinary tract function to coincide with successful micturition after removal of urethral catheter. The aim of this study was to analyze the recovery of bladder function following colorectal surgery. Methods Patients undergoing colorectal operations underwent preoperative and postoperative uroflowmetry and residual urine estimation. All patients were catheterized suprapubically at surgery. Uroflowmetry and postvoid residual volumes were recorded postoperatively until recovery of bladder function was complete. Results Thirty consecutive patients underwent suprapubic catheterization, 25 of whom completed the study. Seventeen (68 percent) patients were able to pass urine within 72 hours of surgery. Recovery of lower urinary tract function was delayed in patients undergoing rectal vs. colonic resections (median, 6 vs. 3 days, P = 0.0015). Postvoid residual volumes greater than 200 ml were noted in three (20 percent) patients following rectal resections beyond the tenth postoperative day, with complete emptying achieved by six weeks. Conclusions Apparent successful micturition following rectal resections does not always indicate recovery of bladder function. The use of suprapubic catheters, in addition to being safe and effective, allows assessment of residual volumes postoperatively and smoothes the path to full recovery of lower urinary tract function.

Use of Acid Suppressive Medications After Laparoscopic Antireflux Surgery: Prevalence and Clinical Indications

Laparoscopic antireflux surgery (LARS) provides effective control of gastroesophageal reflux (GER) in more than 90% of patients. Despite this high success rate, some patients continue to consume acid suppressive medications after surgical intervention. In this study we evaluate the prevalence, clinical indications, and cause of use of acid reducing drugs in patients after LARS. Consecutive patients undergoing LARS for GERD were surveyed 2–3 years after surgery regarding use of acid suppressive medications, surgical outcome, and GERD specific symptoms. During the study period, 119 patients underwent LARS at our center. Ninety-eight (82%) were available for interview. Two patients died of unrelated causes and two declined to be interviewed. The remaining 94 individuals are the subject of this report. Ninety-four percent were satisfied with the outcome of surgery. Despite this high satisfaction rate, 37 of 94 (39%) were on antireflux medication (ARM; 62% proton pump inhibitors, 22% H2-receptor antagonists, and 16% others), with 70% using continuous medication. Of these patients, 54% took ARM after surgery for GERD-related symptoms, 95% of these patients responded to medical therapy, and yet again, 85% remained satisfied with the surgical outcome. Forty-six percent of patients on ARM after surgery had no GERD symptoms and took ARM for nonappropriate indications such as bloating. Only 47% of these responded to ARM; 82% of this group was satisfied with the surgical outcome. In conclusion, the use of ARM after LARS is a common occurrence despite a high satisfaction rate with this operation. Nearly half of patients consuming ARS after LARS are taking these medications for symptoms not necessarily related to GER. These findings underscore the importance of patient education in the use of these agents. The first two authors contributed equally to this article.
