Introduction: Intra-articular injections of hyaluronic acid (HA) could have potential interest in therapy of acute knee trauma injuries, but few results are available in humans. Objective: We reviewed the literature for animal studies of intra-articular HA injections after knee trauma injury to determine the interest of human clinical research into and/or use of such injections for knee trauma. Methods: Systematic literature search on MEDLINE for studies involving animal models of osteoarthritis created by acute knee trauma injury, with HA injections beginning during the 2 weeks after injury. Results: The search revealed 14 studies with a high methodological quality: 7 related to meniscus injury, 3 ACL injury, 1 combined ACL-meniscus injury and 3 cartilage injury. The animal models were rabbits in 10 studies. Four studies demonstrated positive effects and 3 moderate effects of intra-articular HA injection for meniscus injury; 1 positive effects and 2 no effect for ACL injury; 1 positive effects for combined ACL-meniscus injury; and 2 moderate effects and 1 no effect for cartilage injury. Conclusions: With a high strength of recommendation, intra-articular HA injections in animal models with meniscus injury improved the healing process and/or had a protective role in articular cartilage, a slightly protective role in ACL injury animal models and low or no effect on healing in articular cartilage injury animal models. © 2013 Elsevier Ltd.

BACKGROUND:: The impact of intraoperative ventilation on postoperative pulmonary complications is not defined. The authors aimed at determining the effectiveness of protective mechanical ventilation during open abdominal surgery on a modified Clinical Pulmonary Infection Score as primary outcome and postoperative pulmonary function. METHODS:: Prospective randomized, open-label, clinical trial performed in 56 patients scheduled to undergo elective open abdominal surgery lasting more than 2 h. Patients were assigned by envelopes to mechanical ventilation with tidal volume of 9 ml/kg ideal body weight and zero-positive end-expiratory pressure (standard ventilation strategy) or tidal volumes of 7 ml/kg ideal body weight, 10 cm H2O positive end-expiratory pressure, and recruitment maneuvers (protective ventilation strategy). Modified Clinical Pulmonary Infection Score, gas exchange, and pulmonary functional tests were measured preoperatively, as well as at days 1, 3, and 5 after surgery. RESULTS:: Patients ventilated protectively showed better pulmonary functional tests up to day 5, fewer alterations on chest x-ray up to day 3 and higher arterial oxygenation in air at days 1, 3, and 5 (mmHg; mean ± SD): 77.1 ± 13.0 versus 64.9 ± 11.3 (P = 0.0006), 80.5 ± 10.1 versus 69.7 ± 9.3 (P = 0.0002), and 82.1 ± 10.7 versus 78.5 ± 21.7 (P = 0.44) respectively. The modified Clinical Pulmonary Infection Score was lower in the protective ventilation strategy at days 1 and 3. The percentage of patients in hospital at day 28 after surgery was not different between groups (7 vs. 15% respectively, P = 0.42). CONCLUSION:: A protective ventilation strategy during abdominal surgery lasting more than 2 h improved respiratory function and reduced the modified Clinical Pulmonary Infection Score without affecting length of hospital stay.

OBJECTIVES:Magnetic resonance imaging (MRI) allows accurate assessment of Crohn's disease (CD), but requires gadolinium injection. Diffusion-weighted (DW)-MRI yields comparable performances in small bowel CD. We compared the accuracy of DW-MR enterocolonography (MREC) and the magnetic resonance index of activity (MaRIA), and performed an external validation of the Clermont score in assessing inflammation in CD.METHODS:This was an observational prospective study of a single-center cohort. A total of 130 CD patients underwent consecutively MREC with gadolinium injection and DWI sequences between July 2011 and December 2012.RESULTS:Of the 848 evaluated segments (small bowel=352, colon/rectum=496), 175 (20.6%) were active (small bowel=111, colon/rectum=64) defined as MaRIA ≥7. Using a receiver operating characteristic (ROC) curve, we determined an apparent coefficient of diffusion (ADC) threshold of 1.9 × 10 -3 mm 2 /s that yielded a sensitivity and a specificity in discriminating active from nonactive CD of 96.9% and 98.1%, respectively, for the colon/rectum, and 85.9% and 81.6%, respectively, for the ileum. ADC was better correlated to MaRIA ≥7 than related contrast enhancement obtained with injected sequences (P<0.001). The Clermont score (=1.646 × bowel thickness-1.321 × ADC+5.613 × edema+8.306 × ulceration+5.039) was highly correlated with the MaRIA (rho=0.99) in ileal CD but not in colonic CD (rho <0.80). Interobserver agreement was high with regard to ADC measurement (correlation >0.9, P<0.001, and concordance >0.9, P<0001).CONCLUSIONS:DW-MREC is a reliable tool to assess inflammation in colonic (ADC) and ileal (Clermont score) CD and its use in daily practice would avoid gadolinium injection. © 2014 by the American College of Gastroenterology.

Background: Pulmonary function is impaired during pneumoperitoneum mainly as a result of atelectasis formation. We studied the effects of 10 cm H 2O of positive end-expiratory pressure (PEEP) and PEEP followed by a recruitment maneuver (PEEP+RM) on end-expiratory lung volume (EELV), oxygenation and respiratory mechanics in patients undergoing laparoscopic surgery. Methods: Sixty consecutive adult patients (30 obese, 30 healthy weight) in reverse Trendelenburg position were prospectively studied. EELV, static elastance of the respiratory system, dead space, and gas exchange were measured before and after pneumoperitoneum insufflation with zero end-expiratory pressure, with PEEP alone, and with PEEP+RM. Results are presented as mean ± SD. Results: Pneumoperitoneum reduced EELV (healthy weight, 1195 ± 405 vs. 1724 ± 774 ml; obese, 751 ± 258 vs. 886 ± 284 ml) and worsened static elastance and dead space in both groups (in all P < 0.01 vs. zero-end expiratory pressure before pneumoperitoneum) whereas oxygenation was unaffected. PEEP increased EELV (healthy weight, 570 ml, P < 0.01; obese, 364 ml, P < 0.01) with no effect on oxygenation. Compared with PEEP alone, EELV and static elastance were further improved after RM in both groups (P < 0.05), as was oxygenation (P < 0.01). In all patients, RM-induced change in EELV was 16% (P = 0.04). These improvements were maintained 30 min after RM. RM-induced changes in EELV correlated with change in oxygenation (r = 0.42, P < 0.01). Conclusion: RM combined with 10 cm H2O of PEEP improved EELV, respiratory mechanics, and oxygenation during pneumoperitoneum whereas PEEP alone did not. © 2010, the American Society of Anesthesiologists, Inc.

Purpose of review: Tissue hypoxia is a key trigger for organ dysfunction. The maintenance of adequate tissue oxygenation is therefore of particular importance during major surgery. In this review, we discuss the physiological basis and the rationale underlying the recent concepts of perioperative oxygen therapy. Recent findings: Adequate tissue oxygenation is vital for optimal tissue healing in the surgical context. Nevertheless, the definitive proof for a beneficial effect of perioperative oxygen therapy with an increase in inspired oxygen has not been established. In contrast, optimization of oxygen delivery (DO2), using either or both fluid loading and inotropic supports, to prevent tissue hypoxia in relation to an increased oxygen consumption (VO2) could improve outcome. In this context, the use of central venous oxygen saturation (ScvO2), which reflects important changes in the DO2/VO2 relationship and of central venous-to-arterial carbon dioxide difference, to address adequacy of oxygen utilization, has shown promising results. Summary: Adequacy of oxygen delivery to tissue oxygen metabolic demand is essential during the perioperative period. The benefit of perioperative oxygen therapy is rather optimizing the DO2 than increasing inspired oxygen. Improving DO2 has been demonstrated in the perioperative period to reduce both morbidity and mortality. Adaptation of DO2 to O2 consumption using specific goals seems promising. © 2010 Wolters Kluwer Health | Lippincott Williams & Wilkins.

Background: Effective postoperative analgesia is essential for early rehabilitation after surgery. Continuous wound infiltration (CWI) of local anesthetics has been proposed as an alternative to epidural analgesia (EA) during colorectal surgery. This prospective, double-blind trial compared CWI and EA in patients undergoing elective open colorectal surgery. Methods: Fifty consecutive patients were randomized to receive EA or CWI for 48 h. In both groups, patients were managed according to Enhanced Recovery After Surgery recommendations. The primary outcome was the dynamic pain score measured during mobilization 24 h after surgery (H24) using a 100-mm verbal numerical scale. Secondary outcomes were time to functional recovery, analgesic technique-related side effects, and length of hospital stay. Results: Median postoperative dynamic pain score was lower in the EA than in the CWI group (10 [interquartile range: 1.6-20] vs. 37 [interquartile range: 30-49], P < 0.001) and remained lower until hospital discharge. The median times to return of gut function and tolerance of a normal, complete diet were shorter in the EA than in the CWI group (P < 0.01 each). Sleep quality was also better in the EA group, but there was no difference in urinary retention rate (P = 0.57). The median length of stay was lower in the EA than in the CWI group (4 [interquartile range: 3.4-5.3] days vs. 5.5 [interquartile range: 4.5-7] days; P = 0.006). Conclusion: Within an Enhanced Recovery After Surgery program, EA provided quicker functional recovery than CWI and reduced length of hospital stay after open colorectal surgery. © 2013, the American Society of Anesthesiologists, Inc.

Background: Neurally adjusted ventilatory assist (NAVA) is a new mode of mechanical ventilation that delivers ventilatory assist in proportion to the electrical activity of the diaphragm. This study aimed to compare the ventilatory and gas exchange effects between NAVA and pressure support ventilation (PSV) during the weaning phase of critically ill patients who required mechanical ventilation subsequent to surgery. Methods: Fifteen patients, the majority of whom underwent abdominal surgery, were enrolled. They were ventilated with PSV and NAVA for 24 h each in a randomized crossover order. The ventilatory parameters and gas exchange effects produced by the two ventilation modes were compared. The variability of the ventilatory parameters was also evaluated by the coefficient of variation (SD to mean ratio). Results: Two patients failed to shift to NAVA because of postoperative bilateral diaphragmatic paralysis, and one patient interrupted the study because of worsening of his sickness. In the other 12 cases, the 48 h of the study protocol were completed, using both ventilation modes, with no signs of intolerance or complications. The PaO2/FIO2 (mean ± SD) ratio in NAVA was significantly higher than with PSV (264±71 vs. 230±75 mmHg, P<0.05). PaCO2 did not differ significantly between the two modes. The tidal volume (median [interquartile range]) with NAVA was significantly lower than with PSV (7.0 [6.4-8.6] vs. 6.5 [6.3-7.4] ml/kg predicted body weight, P < 0.05).Variability of insufflation airway pressure, tidal volume, and minute ventilation were significantly higher with NAVAthan with PSV. Electrical activity of the diaphragm variability was significantly lower with NAVA than with PSV. Conclusions: Compared with PSV, respiratory parameter variability was greater with NAVA, probably leading in part to the significant improvement in patient oxygenation. Copyright © 2010.

Objectives: There is no standardised technique for internal iliac artery aneurysm (IIAA) embolisation and results of long-term prevention of rupture are unknown. Design: We retrospectively evaluated technical aspects and results of IIAA embolisation in a multicentre study. Methods: Aneurysm morphology and embolisation techniques were reviewed. Aneurysm-related death, rupture, diameter increase, endoleak, secondary procedure and complication related to the IIA occlusion were recorded. Results: Between 2001 and 2011, 53 patients with 57 IIAA were treated. Mean diameter of IIAA was 41 mm (range: 25-88 mm). Embolisation techniques were distal and proximal occlusion (n = 24), proximal occlusion (n = 18) and sac packing (n = 15). Cumulative overall survival rate was 92% at 1 year, 83% at 3 years and 59% at 5 years. No cause of deaths was related to aneurysm. Aneurysm diameter increased in five patients and endoleak was observed in 11 patients. One secondary open conversion and five secondary endovascular procedures were performed for increase of diameter or proximal endoleak. Two patients experienced a disabling buttock claudication. Conclusions: Embolisation of IIAA is safe in the short- and midterm. However, endoleak and aneurysm diameter increases are not rare. Yearly post-procedure computed tomography angiography seems appropriate.© 2012 European Society for Vascular Surgery. Published by Elsevier Ltd. All rights reserved.

Frailty is the loss of resources in several domains leading to the inability to respond to physical or psychological stress. The evaluation of frailty is generally carried out using the Comprehensive Geriatric Assessment. For this evolving and potentially reversible syndrome, screening and early intervention are a priority in primary health care, and general practitioners require a simple screening tool. The aim of the present work was to review the literature for validated screening instruments for frailty in primary health care setting. A search was carried out on PubMed and Cochrane Central in June 2011. A total of 10 instruments screening for frailty in primary health care were listed, analysed and compared. It is difficult to show which tool today is the best for screening for frailty in the elderly in primary care settings. Two instruments are potentially suitable - the Tilburg Frailty Indicator and the SHARE Frailty Index. In addition, these instruments require validation in larger studies in primary health care settings and with more quality criteria. © 2012 Japan Geriatrics Society.

Background: Patient-ventilator asynchrony is common during noninvasive ventilation (NIV) with pressure support ventilation (PSV). We examined the effect of neurally adjusted ventilatory assist (NAVA) delivered through a facemask on synchronization in patients with acute respiratory failure (ARF). Methods: This was a prospective, physiologic, crossover study of 13 patients with ARF (median PaO2/FIO2, 196 [interquartile range (IQR), 142-225]) given two 30-min trials of NIV with PSV and NAVA in random order. Diaphragm electrical activity (EAdi), neural inspiratory time (T I n), trigger delay (Td), asynchrony index (AI), arterial blood gas levels, and patient discomfort were recorded. Results: There were significantly fewer asynchrony events during NAVA than during PSV (10 [IQR, 5-14] events vs 17 [IQR, 8-24] events, P = .017), and the occurrence of severe asynchrony (AI > 10%) was also less under NAVA(P = .027). Ineffective efforts and delayed cycling were significantly less with NAVA(P < .05 for both). NAVA was also associated with reduced Td (0 [IQR, 0-30] milliseconds vs 90 [IQR, 30-130] milliseconds, P < .001) and inspiratory time in excess (10 [IQR, 0-28] milliseconds vs 125 [IQR, 20-312] milliseconds, P,.001), but T I n was similar under PSV and NAVA. The EAdi signal to its maximal value was higher during NAVA than during PSV (P = .017). There were no significant differences in arterial blood gases or patient discomfort under PSV and NAVA. Conclusion: In view of specific experimental conditions, our comparison of PSV and NAVA indicated that NAVA signifi cantly reduced severe patient-ventilator asynchrony and resulted in similar improvements in gas exchange during NIV for ARF.
