A randomized controlled trial evaluating low-intensity shockwave therapy for treatment of persistent storage symptoms following transurethral surgery for benign prostatic obstruction.

BACKGROUND: Low-intensity shockwave therapy (Li-SWT) can improve bladder function through enhancement of angiogenesis and nerve regeneration and suppression of inflammation and overactivity. In this trial, we aimed to evaluate the efficacy of Li-SWT on persistent storage symptoms after transurethral surgery (TUS) for benign prostatic obstruction (BPO). METHODS: Between July 2020 and July 2022, 137 patients with persistent storage symptoms; urgency episodes/24 h ≥ 1 and daytime frequency ≥8, for at least three months after TUS for BPO were randomly allocated to Li-SWT versus sham versus solifenacin 10 mg/day in 3:1:1 ratio. The primary end point was the percent reduction from baseline in overactive bladder symptom score (OABSS) at 3-month follow-up. The changes in 3-day voiding diary parameters, quality of life (QoL) score, peak flow rate and residual urine at 3 and 6-month follow-up were compared. Treatment-related adverse effects were also evaluated. RESULTS: Baseline data were comparable between groups. The percent reduction from baseline in OABSS at 3-month follow-up was significantly higher in Li-SWT compared to sham (-55% versus -11%), and it was comparable between Li-SWT and solifenacin-10 (-55% versus -60%). Li-SWT achieved significant improvement like solifenacin-10 in 3-day voiding diary parameters and QoL score at 3-month follow-up. This improvement remained comparable between Li-SWT and solifenacin-10 at 6-month follow-up. No adverse effects related to Li-SWT were noted apart from tolerable pain during the procedure. Solifenacin-10 was associated with bothersome adverse effects in 73% of the patients with 11.5% discontinuation rate. CONCLUSIONS: Li-SWT ameliorates persistent storage symptoms and promotes QoL after TUS for BPO, with comparable efficacy and better tolerance compared to solifenacin.

Randomized trial to assess the potential role of ascorbic acid and statin for post-contrast acute kidney injury prevention.

PURPOSE: To evaluate the effect of using statins and ascorbic acid for the prevention of post-contrast acute kidney injury (PC-AKI) in patients undergoing urologic diagnostic elective contrast-enhanced computed tomography (CECT). METHODS: This registered trial (NCT03391830) was for statin naïve patients underwent elective CECT. Patients were randomized allocated to two groups: the first group received atorvastatin 80-mg the day before the study and atorvastatin 40-mg two hours before the CECT and for continue on atorvastatin 40-mg two days after CECT; plus ascorbic acid 500 mg with atorvastatin. The other group received two tablets of placebo once/daily before the procedure and for another 3 days. The primary outcome was to assess the incidence PC-AKI. RESULTS: The baseline parameters were comparable between both groups. The final median (interquartile range "IQR") serum creatinine were 0.80 (0.60, 1.00) and 0.80 (0.60, 1.00), respectively, with insignificant p-value (p = 0.8). The median (IQR) final estimated GFR were 95.2 (72.8, 108.1) and 88.6 (71.9, 111.0) mL/min in placebo and statin plus ascorbic acid groups, respectively (p = 0.48). The eGFR difference median (IQR) were - 6.46 (- 11.72, - 4.18) and - 6.57 (- 13.38, - 3.82) ml/min in placebo and statin plus ascorbic acid groups, respectively (p = 0.58). PC-AKI occurred in 11 patients (9.8%) in placebo group and in 3 patients (3%) in statin plus ascorbic acid group (p = 0.04). CONCLUSIONS: Statin and ascorbic acid did not statistically improve neither serum creatinine nor eGFR values in patient underwent CECT. However, it can decrease the incidence of the clinically insignificant PC-AKI.

A Single-Step Genome-Wide Association Study for Semen Traits of Egyptian Buffalo Bulls.

The present study aimed to contribute to the limited research on buffalo (Bubalus bubalis) semen traits by incorporating genomic data. A total of 8465 ejaculates were collected. The genotyping procedure was conducted using the Axiom® Buffalo Genotyping 90 K array designed by the Affymetrix Expert Design Program. After conducting a quality assessment, we utilized 67,282 SNPs genotyped in 192 animals. We identified several genomic loci explaining high genetic variance by employing single-step genomic evaluation. The aforementioned regions were located on buffalo chromosomes no. 3, 4, 6, 7, 14, 16, 20, 22, and the X-chromosome. The X-chromosome exhibited substantial influence, accounting for 4.18, 4.59, 5.16, 5.19, and 4.31% of the genomic variance for ejaculate volume, mass motility, livability, abnormality, and concentration, respectively. In the examined genomic regions, we identified five novel candidate genes linked to male fertility and spermatogenesis, four in the X-chromosome and one in chromosome no. 16. Additional extensive research with larger sample sizes and datasets is imperative to validate these findings and evaluate their applicability for genomic selection.

Instrumented assisted soft tissue mobilization vs extracorporeal shock wave therapy in treatment of myofascial pain syndrome.

BACKGROUND: Active myofascial trigger points (TrPs) often occur in the upper region of the upper trapezius (UT) muscle. These TrPs can be a significant source of neck, shoulder, and upper back pain and headaches. These TrPs and their related pain and disability can adversely affect an individual's everyday routine functioning, work-related productivity, and general quality of life. AIM: To investigate the effects of instrument assisted soft tissue mobilization (IASTM) vs extracorporeal shock wave therapy (ESWT) on the TrPs of the UT muscle. METHODS: A randomized, single-blind, comparative clinical study was conducted at the Medical Center of the Egyptian Railway Station in Cairo. Forty patients (28 females and 12 males), aged between 20-years-old and 40-years-old, with active myofascial TrPs in the UT muscle were randomly assigned to two equal groups (A and B). Group A received IASTM, while group B received ESWT. Each group was treated twice weekly for 2 weeks. Both groups received muscle energy technique for the UT muscle. Patients were evaluated twice (pre- and post-treatment) for pain intensity using the visual analogue scale and for pain pressure threshold (PPT) using a pressure algometer. RESULTS: Comparing the pre- and post-treatment mean values for all variables for group A, there were significant differences in pain intensity for TrP1 and TrP2 (P = 0.0001) and PPT for TrP1 (P = 0.0002) and TrP2 (P = 0.0001). Also, for group B, there were significant differences between the pre- and post-treatment pain intensity for TrP1 and TrP2 and PPT for TrP1 and TrP2 (P = 0.0001). There were no significant differences between the two groups in the post-treatment mean values of pain intensity for TrP1 (P = 0.9) and TrP2 (P = 0.76) and PPT for TrP1 (P = 0.09) and for TrP2 (P = 0.91). CONCLUSION: IASTM and ESWT are effective methods for improving pain and PPT in patients with UT muscle TrPs. There is no significant difference between either treatment method.

Association of IL-17F Gene Polymorphism and Its Serum Level with SARS-CoV-2 Infection.

OBJECTIVE: Although multiple studies have addressed the clinical outcomes of coronavirus disease, little data exist regarding the defi- nition of immune and inflammatory profiles associated with this infection. Its clinical manifestations often worsen in association with hypercytokinemia (elevated interleukin 8 and interleukin 17). We conducted this research to elucidate the effect of interleukin 17 levels and interleukin 17F gene polymorphism on the severity and outcomes of coronavirus disease. MATERIAL AND METHODS: Ninety patients with confirmed coronavirus disease and 30 healthy controls were enrolled. Coronavirus disease cases were classified into nonsevere, severe, and critical according to the World Health Organization definition. Approximately 10 mL peripheral blood sample was collected from all patients and controls by venipuncture in-plane and ethylenediaminetetraacetic acid tube. Enzyme-linked immunosorbent assay kits were used for calculating serum interleukin 17 levels, whereas real-time polymerase chain reaction was used for genotyping using the 5'-nuclease allelic discrimination assay for single nucleotide polymorphisms genotyping. RESULTS: As regards interleukin 17 levels, there was a significant elevation of interleukin 17 in coronavirus disease cases compared to control healthy persons (P < .001). Moreover, serum interleukin 17 levels tended to be significantly higher with increased disease sever- ity (P = .004). Patients with critical diseases expressed a significant rise of interleukin 17 compared to severe (P = .03) and nonsevere cases (P = .02). We noted no significant difference between the critical, severe, and nonsevere cases regarding different interleukin 17F genotypes. CONCLUSION: Coronavirus disease is associated with elevated levels of interleukin 17, which tended to be considerably higher with disease severity. However, different interleukin 17F genotypes do not affect either the predisposition or the severity of coronavirus disease.

Resource utilization in management of spontaneous intracerebral hemorrhage without systemic risk factors. Does early surgical decompression matter?

BACKGROUND: Even though different subtypes of spontaneous ICH are frequently linked to a poor prognosis, their causes, pathological features, and prognoses vary. Atypical intracerebral hemorrhage is the subtype of spontaneous ICH that usually occurs due to an underlying localized vascular lesion. It is unrelated to systemic vascular risk factors, mostly affects children and young adults and is associated with a relatively good outcome. This fact should be considered when planning the evaluation and treatment. Investigating the cause of this subtype is fundamental to providing optimal management. However, if resources do not allow completing the investigations, the cause will be more difficult to discover. Treatment decisions will be made under stress to save the patient's life, especially with rapidly deteriorating patients. METHODS: We described three cases of spontaneous ICH without systemic risk factors where the bleeding source could not be determined before surgery due to a lack of resources, preventing preoperative vascular investigation. Knowing that the atypical ICH has a distinct identity, regarding etiology and prognosis, encouraged the surgeons to resort to early surgical decompression as an alternative plan. We reviewed the literature searching for supporting evidence. RESULTS: The results of treatment of the presented cases were satisfactory. The lack of reported similar cases was brought to light by a literature analysis that sought to provide backing for the proposed management strategy. In the end, we supplied two graphic organizers to help readers remember the different types and treatment of hemorrhagic stroke. CONCLUSION: There isn't enough evidence to show that there are other ways to treat atypical intracerebral haemorrhage when resources are limited. The presented cases highlight the importance of decisionmaking in resource-constrained situations when patient outcomes can be improved.

Fungating and Ulcerating Breast Cancer: Wound Closure Algorithm, Complications, and Survival Trends.

Fungating breast cancer severely affects patients' daily lives, and patient management poses major oncology challenges. To present 10-year outcomes of unique tumor presentation, suggesting a focused algorithm for surgical management and providing deep analysis for factors affecting survival and surgical outcomes. Eighty-two patients with fungating breast cancer were enrolled in the period from January 2010 to February 2020 in the Mansoura University Oncology Center database. Epidemiological and pathological characteristics, risk factors, different surgical treatment techniques, and surgical and oncological outcomes were reviewed. Preoperative systemic therapy was used in 41 patients, with the majority (77.8%) showing progressive response. Mastectomy was performed in 81 (98.8%) patients, with primary wound closure in 71 (86.6%), and wide local excision in a single patient (1.2%). Different reconstructive techniques in non-primary closure operations were used. Complications were reported in 33 (40.7%) patients, of which 16 (48.5%) were of Clavien-Dindo grade II category. Loco-regional recurrence occurred in 20.7% of patients. The mortality rate during follow-up was 31.7% (n = 26). Estimated mean overall survival (with 95% CI) was 55.96 (41.98-69.9) months; estimated mean loco-regional recurrence-free survival (with 95% CI) was 38.01 (24.6-51.4) months. Surgery is a cornerstone fungating breast cancer treatment option, but at the expense of high morbidity. Sophisticated reconstructive procedures may be indicated for wound closure. A suggested algorithm based on the center's experience of wound management in difficult mastectomy cases is displayed.

Eccentric Versus Concentric Exercises in Patients With Rheumatoid Arthritis and Rotator Cuff Tendinopathy: A Randomized Comparative Study.

OBJECTIVE: To determine the efficacy of concentric vs. eccentric exercise in improving shoulder function, pain, and tendon characteristics for patients with rheumatoid arthritis and rotator cuff tendinopathy. METHODS: Forty patients with rheumatoid arthritis and rotator cuff tendinopathy were divided into either concentric or eccentric exercise groups, with 20 patients in each group. Patients received 12 sessions at a pace of 3 sessions per week. Shoulder Pain and Disability Index (SPADI), the visual analogue scale (VAS), supraspinatus and subscapularis thickness, echo pixels, and the Disease Activity Score-28-erythrocyte sedimentation rate (DAS-28-ESR) were assessed at baseline and post-treatment. RESULTS: There was a significant difference between the concentric and eccentric groups regarding SPADI and VAS scores in favor of the eccentric group. However, there was no significant difference between the two groups regarding tendon thickness, echo pixels, or DAS-28-ESR. CONCLUSION: Eccentric exercises were more effective than concentric exercises in improving shoulder function and pain intensity. However, neither of the two types of exercises was superior in improving tendon characteristics or disease activity.

Thermal performance enhancement of the wick-type solar still using titanium dioxide nanoparticles embedded in paraffin wax as a phase change material.

In this study, the performance of the wick-type solar still was investigated using phase change material (PCM) with titanium dioxide nanoparticles as a storage material. Therefore, two solar stills were fabricated one of which was operated with pure PCM and the other one was operated with PCM incorporated with Tio2 nanoparticles. The use of the nanoparticles was to enhance the thermal conductivity of the PCM and hence improve the productivity and the efficiency of the studied solar still. The proposed design was investigated with jute and cotton as wick materials. The results revealed that the addition of the nanoparticles increased the thermal conductivity of the PCM by 9.6%. Moreover, the daily productivity was found to be 1058 and 1226 ml/m2 day for cotton and jute, respectively in case of the presence of the PCM-nanocomposite.

Nursing Mothers' Experiences of Musculoskeletal Pain Attributed to Poor Posture During Breastfeeding: A Mixed Methods Study.

Background: Breastfeeding has various benefits for infants and mothers. However, if not performed in the correct posture, prolonged breastfeeding could cause musculoskeletal-related symptoms such as shoulder, neck, and upper back pain. In Jordan, nursing mothers do not have access to a breastfeeding midwifery team, a breastfeeding dietician, or a breastfeeding nurse for advice and education. The primary aim of this study was to explore nursing mothers' experiences of breastfeeding-related musculoskeletal pain; secondary aims were to explore nursing mothers' awareness of recommended breastfeeding postures and their experience of education and advice about breastfeeding postures. Methods: A cross-sectional mixed methods study was conducted with nursing mothers in Jordan who have breastfed their babies for 6 months or more following normal delivery, using an online survey questionnaire and semi-structured interviews. Participants were recruited through general practitioner clinics. Results: Four hundred ninety-three nursing mothers submitted the online questionnaire, and 12 interviews were completed. Nursing mothers reported experiencing nonspecific pain in lower back, neck, shoulder, and hand, attributed to breastfeeding. Pain in these joints affected mood, sleep, working ability, and quality of life by limiting activities of daily living. Findings showed that the majority of Jordanian nursing mothers did not receive education about safe or optimal breastfeeding positioning from health professionals. Conclusions: Nursing mothers in Jordan are not receiving appropriate education or advice about optimal postures for breastfeeding and have reported experiencing musculoskeletal pain, attributed to breastfeeding, that interferes with activities of daily living and affects quality of life. Postural education and advice should be provided to nursing mothers to prevent or avoid development of musculoskeletal pain.

Q-Switched 1064-nm Nd: YAG laser versus fractional carbon dioxide laser for post acne scarring: A split-face comparative study.

OBJECTIVES: Many treatment modalities are available for post acne scarring. However, the response to the treatment is extremely variable among patients. AIM: The aim of this study was to compare the efficacy and safety of Q-switched Nd: YAG (1064 nm) and fractional CO2 (10,600 nm) lasers in the treatment of atrophic post acne scars. METHODS: This study included 20 patients with atrophic facial post acne scars graded according to Sharquie's score. All subjects received four sessions of laser treatment with a 4-week interval between the sessions. The study was designed as a double-blinded, comparative, split-face study applying Q-switched 1064-nm Nd:YAG laser to the right side of the face and fractional CO2  laser to the left side. RESULTS: Q-switched 1064-nm Nd: YAG laser achieved significantly higher improvement percentage when compared to fractional CO2  lasers (33.33% versus 17.37% Sharquie's score reduction, respectively). There was a significant negative correlation between the percentages of improvement and the patients' age on both sides and a significant positive correlation with the baseline Sharquie scores on both sides. CONCLUSION: Q-Switched 1064-nm Nd: YAG laser could be a promising safe option for the management of atrophic post acne scars.

The alternating bidirectional versus the standard approach during shock wave lithotripsy for upper lumbar ureteric stones: a randomized controlled trial.

PURPOSE: To compare the outcome of shock wave lithotripsy (SWL) for upper lumbar ureteric stones using the alternating bidirectional approach versus the standard approach during the first session. METHODS: Our study was a randomized controlled trial including patients with single radio-opaque stone < 1 cm located in the upper lumbar ureter (from the ureteropelvic junction till the level medial to the lower margin of the kidney). SWL was conducted using electromagnetic Dornier Gemini Lithotripter. In group 1, patients were treated with the alternating under and over-table approach during the first session only and if other sessions were needed, the standard under-table approach was used. In group 2, patients were treated with the standard under-table approach during all sessions. Stone disintegration after the first session was assessed by kidney-ureter-bladder X-ray, renal ultrasonography and noncontrast computed tomography. Moreover, the incidence and severity of postoperative complications were evaluated. RESULTS: Forty-eight patients in each group completed the study. Patient demographics and stone characteristics were comparable in both groups. Complete disintegration was achieved in 41.7% of patients in group 1 versus 18.8% in group 2 (P = 0.021). Stone-free rate (SFR) was 58.3% and 20.8% in group 1 and 2 respectively (P = 0.001). The mean session time was 56.42 min in group 1 versus 46.35 min in group 2 (P < 0.001). There was no significant difference in postoperative complications. CONCLUSION: Stone disintegration and SFR after the first SWL session are higher when using the alternating bidirectional approach for upper lumbar ureteric stones at the expense of longer procedural duration.

Ultrasound versus thoracoscopic-guided paravertebral block during thoracotomy.

BACKGROUND: Paravertebral block can be performed with the aid of surgical landmarks, ultrasound, or a thoracoscope. This study was designed to compare ultrasound-guided paravertebral block with the thoracoscopic technique. METHODS: This prospective randomized comparative study included 40 adults scheduled for elective thoracic surgery. Study participants were randomized to an ultrasound group or a thoracoscope group. A catheter for paravertebral block was inserted prior to thoracotomy with real-time ultrasound visualization in the ultrasound group, and under thoracoscopic guidance in the thoracoscope group. Total analgesic consumption, visual analogue pain score, technical difficulties, and complications were compared between the 2 groups. RESULTS: Total analgesic consumption in the first 24 hours was less in the ultrasound group than in the thoracoscope group (rescue intravenous fentanyl 121.25 ± 64.01 µg in the ultrasound group vs. 178.75 ± 91.36 µg in the thoracoscope group; p = 0.027). Total paravertebral bupivacaine consumption was 376.00 ± 33.779 mg in the ultrasound group and 471.50 ± 64.341 mg in the thoracoscope group (p < 0.001). Technical difficulties and complications in terms of time consumed during the maneuver, more than one needle pass, and pleural puncture were significantly lower in the ultrasound group than in the thoracoscope group. CONCLUSION: Ultrasound-guided paravertebral catheter insertion is more effective, technically easier, and safer than the thoracoscope-assisted technique.

Effect of Adding Hydrocortisone to Intraperitoneal Bupivacaine in Laparoscopic Bariatric Surgery.

BACKGROUND: Bariatric surgery is the effective management of obesity; however, postoperative pain is associated with a great morbidity. The management of pain is important for the enhancement of patient recovery. Local anesthetics can be injected during laparoscopic surgery into the peritoneum throughout the ports produced either before the beginning of laparoscopy or before the closure of the wound to reduce postoperative pain. Our aim is to evaluate if there is an additive analgesic effect by the administration of intraperitoneal hydrocortisone with streamed intraperitoneal bupivacaine as a method of postoperative pain relief in laparoscopic bariatric surgeries. PATIENTS AND METHODS: One hundred patients listed for laparoscopic bariatric surgery were the subject of this study. Patients were randomly allocated into two groups: Group I received 100 mg of 0.5% isobaric bupivacaine plus 20 mL normal saline intraperitoneally and Group II received intraperitoneal 100 mg of 0.5% isobaric bupivacaine + 100 mg hydrocortisone + 20 mL of saline at the end of the laparoscopic procedure. The primary outcome was the Visual Analog Scale (VAS) score for pain. The secondary outcomes were the time of first analgesic request, total opioid requirement, heart rate, and mean blood pressure. RESULTS: VAS showed a significant decrease at 4, 6, and 12 h postoperative in Group II compared to Group I. There was a marked decrease in total meperidine requirement with prolonged time of the first analgesic request in Group II compared to Group I. CONCLUSION: Intraperitoneal hydrocortisone with bupivacaine had improved postoperative pain relief with a decrease in analgesic requirement.

Operative bleeding during thoracoscopic thymectomy: Causes and management strategies.

Bleeding during thoracoscopic thymectomy is a potentially critical complication that necessitates either immediate effective thoracoscopic control or conversion to an open approach. It can be difficult to manage and the surgeon must respond quickly in order to keep the patient safe . In this video tutorial we present various forms of intraoperative bleeding that can occur during thoracoscopic thymectomy and discuss how to manage them in patients with myasthenia gravis. Our management techniques include compression, clipping, stitching, and safe conversion to an open approach.

Recurrent mandibular ameloblastoma in soft tissue and rib graft 17 years after initial presentation.

BACKGROUND: Ameloblastoma is the commonest odontogenic tumour of epithelial origin with a high incidence for developing local recurrence. We present a patient who developed local recurrence in both soft tissue and bone graft 17 years after the initial presentation. CASE PRESENTATION: A 75-year-old female with a previous history of right hemimandibulectomy and rib reconstruction for ameloblastoma in 1999 presented to our centre with a large cystic mouth floor swelling, biopsy from which revealed recurrent ameloblastoma. The patient underwent excision of the recurrent mass en bloc with the cystic swelling through oral and cervical approaches. The patient was discharged after 5 days with an uneventful postoperative course and with a free 2-year follow-up from further recurrence. CONCLUSION: Ameloblastoma is a locally aggressive tumour for which wide local excision with adequate margins is the best management approach. Recurrence of ameloblastoma even after adequate resection is not uncommon, and its management is considered a surgical challenge. A very long time may pass between the initial presentation and the development of recurrence.

Comparative study of three different designs of a hybrid PV/T double-pass finned plate solar air heater.

In this paper, three different designs of a hybrid PV/T double-pass finned plate solar air heater (DPFPSAH) are investigated. The PV module is used to produce electricity needed to run the pump and blow the air into the solar collector. In the first design, the PV module is placed on the absorber plate of the air heater. In the second design, the PV module is placed beside the glass cover of the air heater; while, in the third one, the PV module is completely separated from the solar collector. The effects of mass flow rate of air, flow, and fan pumping powers are studied. The top losses of the third design are found to be higher than that of the first and the second designs by average values of 7.5% and 29%, respectively. The third design of the hybrid systems has the highest overall performance. The daily thermal efficiencies of the first, second, and third designs of the hybrid systems are obtained as 53%, 27%, and 64%, respectively, at mass flow rate of 0.02 kg/s.

Cardiac Preconditioning Effect of Ketamine-Dexmedetomidine versus Fentanyl-Propofol during Arrested Heart Revascularization.

BACKGROUND: Myocardial damage due to ischemia and reperfusion is still unavoidable during coronary surgery. Anesthetic agents have myocardial preconditioning effect. Ketamine has sympathomimetic effect, while dexmedetomidine has a sympatholytic effect in addition to anesthetic, analgesic, and anti-inflammatory properties of both the drugs. This study was carried out to compare ketamine-dexmedetomidine (KD) combination with fentanyl-propofol (FP) combination on the release of cardiac troponin T (cTnT) and outcome after coronary artery bypass graft. PATIENTS AND METHODS: Ninety adult patients who underwent coronary artery bypass grafting (CABG) were assigned to receive either KD base anesthesia (KD group) or FP anesthesia (FP group). Trends of high-sensitive cTnT, CK-MB, and serum cortisol were followed in the first postoperative 24 h. Other outcomes were vital signs, weaning from cardiopulmonary bypass, tracheal extubation time, and echocardiographic findings. RESULTS: There was a significant lower release of cTnT in KD group than FP group during its peak values at 6 h after aortic unclamping (92.01 ± 7.332 in KD versus 96.73 ± 12.532 ng.L-1 P = 0.032). significant lower levels of serum cortisol levels were noted KD group than in FP group at 6 and 12 h after aortic unclamping P < 0.001. As regard tracheal extubation time, patients assigned to KD group extubated earlier than whom in FP group 202.22 ± 28.674 versus 304.67 ± 40.598 min respectively P < 0.001. CONCLUSION: The use of KD during on-pump CABG confers better myocardial protective and anti-inflammatory effect than fentanyl propofol.

Volatile Anesthetics versus Total Intravenous Anesthesia for Cardiac Surgery.

BACKGROUND: Volatile (inhaled) anesthetic agents have cardioprotective effects, which might improve clinical outcomes in patients undergoing coronary-artery bypass grafting (CABG). METHODS: We conducted a pragmatic, multicenter, single-blind, controlled trial at 36 centers in 13 countries. Patients scheduled to undergo elective CABG were randomly assigned to an intraoperative anesthetic regimen that included a volatile anesthetic (desflurane, isoflurane, or sevoflurane) or to total intravenous anesthesia. The primary outcome was death from any cause at 1 year. RESULTS: A total of 5400 patients were randomly assigned: 2709 to the volatile anesthetics group and 2691 to the total intravenous anesthesia group. On-pump CABG was performed in 64% of patients, with a mean duration of cardiopulmonary bypass of 79 minutes. The two groups were similar with respect to demographic and clinical characteristics at baseline, the duration of cardiopulmonary bypass, and the number of grafts. At the time of the second interim analysis, the data and safety monitoring board advised that the trial should be stopped for futility. No significant difference between the groups with respect to deaths from any cause was seen at 1 year (2.8% in the volatile anesthetics group and 3.0% in the total intravenous anesthesia group; relative risk, 0.94; 95% confidence interval [CI], 0.69 to 1.29; P = 0.71), with data available for 5353 patients (99.1%), or at 30 days (1.4% and 1.3%, respectively; relative risk, 1.11; 95% CI, 0.70 to 1.76), with data available for 5398 patients (99.9%). There were no significant differences between the groups in any of the secondary outcomes or in the incidence of prespecified adverse events, including myocardial infarction. CONCLUSIONS: Among patients undergoing elective CABG, anesthesia with a volatile agent did not result in significantly fewer deaths at 1 year than total intravenous anesthesia.
