Bleeding Tendency in People Anesthetized with Sevoflurane Vs Isoflurane

Abstract Background & Purpose The effects of desflurane and sevoflurane, two commonly used inhalation anesthetics for the maintenance of general anesthesia, on peri- and postoperative bleeding is a focus of interest. This study conductd to evaluating that; Sevoflurane can cause bleeding tendencies more than Isoflurane anesthesia or not? Study design Prospective, randomized comparative study. Setting Ain shams university hospitals. Subjects We included 40 tonsillectomy patients (age from 2 – 12 years old), and classified them according to the anesthetic drug used into 2 independent groups: Isoflurane group (20 patients) and Sevoflurane group (20 patients). Methods All patients were subjected to full history taking, oral cavity examination, anterior rhinoscopy nasal examination, basic laboratory studies for bleeding tendencies (e.g. platelets and INR), adenoidal-tonsillectomy operational data (including operative time calculation), bleeding outcomes (blood loss and packs of blood transfusion) will be recorded, and half of the cases will be anesthetized with sevoflurane and another half with isoflurane. Results In the studied population, the mean age of all patients was (7.1 ± 2.7) years, with (57.5%) of patients were males; while (42.5%) were females. Regarding bleeding outcome data; the average blood loss of all patients was (15.5 ± 3.7) cc, and the average packs used were (4.2 ± 1.1). We found a significant decrease in operative time in the Isoflurane group; compared to the Sevoflurane group (p = 0.0017). Regarding Bleeding outcome data; we found, a significant decrease in blood loss, in the Isoflurane group; compared to the Sevoflurane group (p = 0.00014), and a significant decrease in the number of packs used, in Isoflurane group; compared to Sevoflurane group (p = 0.0018). Conclusion To conclude, anesthesia with isoflurane can lead to a lower amount of intraoperative bleeding compared with sevoflurane. Therefore, isoflurane may be preferred as an inhalational agent for the maintenance of general anesthesia during tonsillectomy and adenoidectomy operations.

Abstract INTRODUCTION Lumbar spine surgery can be successfully performed using various anesthetic techniques. Previous studies have shown varying results in selected outcomes when directly comparing spinal anesthesia (SA) to general anesthesia (GA) in lumbar surgery. We sought to elucidate the more expedient anesthetic technique. METHODS Following IRB approval, a retrospective review of patients undergoing elective lumbar decompression surgery using GA or SA was performed. Demographic data known to influence perioperative morbidity was collected as well as safety and efficiency parameters. After controlling for patient and procedure characteristics, simple linear and multivariate regression analyses were performed to identify differences in operative blood loss, operative time, time from entering the OR until incision, time from bandage placement to exiting the OR, total anesthesia time, time in the post-anesthesia care unit (PACU), and length of hospital stay. RESULTS >544 consecutive lumbar laminectomy and discectomy surgeries were identified with 183 undergoing GA and 361 undergoing SA. The following times were all shorter for patients receiving SA than GA: operative time (97.4 vs. 151.8 min., P < 0.001), total anesthesia time (145.6 vs. 217.5 min., P < 0.001), time from entering the OR until incision (38.3 vs. 46.8 min., respectively, P < 0.001), time from bandage placement until exiting the OR (10.2 vs. 17.2 min., P < 0.001), and length of hospital stay (1.5 vs. 3.1 days, P < 0.001). The mean PACU length of stay was longer in the SA group than the GA group (178.0 vs. 116.5 min., P < 0.001). Estimated blood loss was less in the SA group than the GA group (62.1 vs. 176.3 mL, P < 0.001). CONCLUSION Spinal anesthesia may be the more expedient method of anesthesia in lumbar spinal surgery for all perioperative time points except for time in the PACU.

Abstract Introduction: The study aimed to compare the 2 procedures of tonsillectomy (coblation and diode laser) concerning the operative time, the amount of blood loss, postoperative pain, and other complications. Materials and Methods: A comparative study was conducted at many Private Hospitals, Baghdad, Iraq from February 2019- February 2020. Coblation and laser tonsillectomy were performed on the same patient (one for each side) which was blinded to the patients or their caregivers and the surgeon who did the tonsillectomy. Data concerning the age, gender, indications for tonsillectomy, operative time, the amount of the blood loss, post-tonsillectomy pain by VAS scores, and other complications were recorded for each patient. Results: Out of 62 participants, there were 34 (54.8%) females. The majority were from the age group ≤18 years (n=54, 87.1%). The operative time and amount of the intraoperative blood loss were significantly lower in the coblation than a diode laser tonsillectomy. However, the postoperative pain scores in the diode laser were a statistically significant difference less than the coblation group at the periods 3 hours, 8 hours, 24 hours, and 7 days (P-value<0.05). While there was no statistically significant difference between the two groups at 2 weeks postoperative period (P-value=0.392). No primary or secondary postoperative bleeding in all patients. Conclusion: coblation was better than diode laser because of shorter operative time and less intraoperative blood loss. However, the diode laser technique had lesser postoperative pain at the postoperative periods 3 hours, 8 hours, 24 hours, and 7 days than coblation.

Cold Dissection

Tonsillectomy is the most commonly performed surgery. Cold dissection tonsillectomy remains as the gold standard for tonsil removal, although it may increase risk for complication. Coblation tonsillectomy is a new technique .There are studies comparing these two method of surgery and have shown coblation technique to cause less postoperative pain, less intra operative time along with less intra and postoperative blood loss. In contrary few studies have shown it to be ineffective in reducing postoperative bleeding. Hence more studies are still required. Thus the objective of the present study was to compare coblation and cold dissection techniques outcome among tonsillectomy patients at Birat Medical College and Teaching Hospital. The study intended to determine and compare the intraoperative time, intra operative blood loss and postoperative pain in coblation and cold dissection tonsillectomy. This is a hospital based cross sectional comparative study. Eighty six patients underwent tonsillectomy during the study period of one year (15th Feb 2020 to 14th Feb 2021) in the department of ENT HNS, Birat Medical College and Teaching Hospital. Among 86 patients, 43 underwent cold dissection and 43 coblation tonsillectomy. Method of surgery was based on odd and even serial number of the patients during presentation. This study showed that intra operative time, intraoperative blood loss and post operative pain score was 16.77±2.7mins, 36.51±128ml and 6.28 respectively in coblation method and 37.84±3.1 mins, 101.4±12.7ml and 7.88 respectively in cold dissection method. Hence coblation method is a safer and effective method of tonsillectomy compared to cold dissection which ultimately leads to less post operative analgesics demands and early recovery.

OBJECTIVEThe purpose of this study was to investigate the effect of tranexamic acid (TXA) compared to placebo in low-risk adult patients undergoing elective minor lumbar spine surgery—specifically with respect to operative time, estimated blood loss, and complications. Studies have shown that TXA reduces blood loss during major spine surgery. There have been no previous studies on the effect of TXA in minor lumbar spine surgery in which these variables have been evaluated.METHODSThe authors enrolled patients with ASA grades 1 to 2 scheduled to undergo lumbar decompressive surgery at Middelfart Hospital into a double-blind, randomized, placebo-controlled, parallel-group study. Patients with thromboembolic disease, coagulopathy, hypersensitivity to TXA, or a history of convulsion were excluded. Patients were randomly assigned, in blocks of 10, to one of 2 groups, TXA or placebo. Anticoagulation therapy was discontinued 2–7 days preoperatively. Prior to the incision, patients received either a bolus of TXA (10 mg/kg) or an equivalent volume of saline solution (placebo). Independent t-tests were used to compare differences between the 2 groups, with statistical significance set at p < 0.05.RESULTSOf the 250 patients enrolled, 17 patients were excluded, leaving 233 cases for analysis (117 in the TXA group and 116 in the placebo group). The demographics of the 2 groups were similar, except for a higher proportion of women in the TXA group (TXA 50% vs placebo 32%, p = 0.017). There was no significant between-groups difference in operative time (49.53 ± 18.26 vs 54.74 ± 24.49 minutes for TXA and placebo, respectively; p = 0.108) or intraoperative blood loss (55.87 ± 48.48 vs 69.14 ± 83.47 ml for TXA and placebo, respectively; p = 0.702). Postoperative blood loss measured from drain output was 62% significantly lower in the TXA group (13.03 ± 21.82 ml) than in the placebo group (34.61 ± 44.38 ml) (p < 0.001). There was no significant difference in number of dural lesions or postoperative spinal epidural hematomas, and there were no thromboembolic events.CONCLUSIONSTranexamic acid did not have a statistically significant effect on operative time, intraoperative blood loss, or complications. This study gives no evidence to support the routine use of TXA during minor lumbar decompressive surgery.Clinical trial registration no.: NCT03714360 (clinicaltrials.gov)

OBJECTIVEPosterior-based thoracolumbar 3-column osteotomy (3CO) is a formidable surgical procedure. Surgeon experience and case volume are known factors that influence surgical complication rates, but these factors have not been studied well in cases of adult spinal deformity (ASD). This study examines how surgeon experience affects perioperative complications and operative measures following thoracolumbar 3CO in ASD.METHODSA retrospective study was performed of a consecutive cohort of thoracolumbar ASD patients who underwent 3CO performed by the senior authors from 2006 to 2018. Multivariate analysis was used to assess whether experience (years of experience and/or number of procedures) is associated with perioperative complications, operative duration, and blood loss.RESULTSA total of 362 patients underwent 66 vertebral column resections (VCRs) and 296 pedicle subtraction osteotomies (PSOs). The overall complication rate was 29.4%, and the surgical complication rate was 8.0%. The rate of postoperative neurological deficits was 6.2%. There was a trend toward lower overall complication rates with greater operative years of experience (from 44.4% to 28.0%) (p = 0.115). Years of operative experience was associated with a significantly lower rate of neurological deficits (p = 0.027); the incidence dropped from 22.2% to 4.0%. The mean operative time was 310.7 minutes overall. Both increased years of experience and higher case numbers were significantly associated with shorter operative times (p < 0.001 and p = 0.001, respectively). Only operative years of experience was independently associated with operative times (p < 0.001): 358.3 minutes from 2006 to 2008 to 275.5 minutes in 2018 (82.8 minutes shorter). Over time, there was less deviation and more consistency in operative times, despite the implementation of various interventions to promote fusion and prevent construct failure: utilization of multiple-rod constructs (standard, satellite, and nested rods), bone morphogenetic protein, vertebroplasty, and ligament augmentation. Of note, the use of tranexamic acid did not significantly lower blood loss.CONCLUSIONSSurgeon years of experience, rather than number of 3COs performed, was a significant factor in mitigating neurological complications and improving quality measures following thoracolumbar 3CO for ASD. The 3- to 5-year experience mark was when the senior surgeon overcame a learning curve and was able to minimize neurological complication rates. There was a continuous decrease in operative time as the surgeon’s experience increased; this was in concurrence with the implementation of additional preventative surgical interventions. Ongoing practice changes should be implemented and can be done safely, but it is imperative to self-assess the risks and benefits of those practice changes.

The aim of this paper is to assess the efficiency and safety of the tranexamic acid in reducing blood loss and the need for transfusion in patients diagnosed with staghorn calculi treated by percutaneous nephrolithotomy. Percutaneous nephrolithotomy (PCNL) is a minimally invasive technique used for large kidney stones. Hemorrhagic complications and urinary sepsis are serious complications associated with this type of surgery. Tranexamic acid is an antifibrinolytic drug that has the property of reducing intra or postoperative bleeding. The experience with tranexamic acid in preventing blood loss during percutaneous nephrolithotomy for is limited. The use tranexamic acid in percutaneous nephrolithotomy for staghorn type stones is safe and is associated with reduced blood loss and a lower transfusion rate.

Objective This study was performed to evaluate the surgical indications, clinical efficacy, and preliminary experiences of nonstructural bone grafts for lumbar tuberculosis (TB). Methods Thirty-four patients with lumbar TB who were treated with nonstructural bone grafts were retrospectively assessed. The operative time, operative blood loss, hospital stay, bone graft fusion time, erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) concentration, visual analog scale (VAS) score, Oswestry Disability Index (ODI), American Spinal Injury Association (ASIA) impairment grade, and Cobb angle were recorded and analyzed. Results The mean operative time, operative blood loss, hospital stay, Cobb angle correction, and Cobb angle loss were 192.59 ± 42.16 minutes, 385.29 ± 251.82 mL, 14.91 ± 5.06 days, 9.02° ± 3.16°, and 5.54° ± 1.09°, respectively. During the mean follow-up of 27.53 ± 8.90 months, significant improvements were observed in the ESR, CRP concentration, VAS score, ODI, and ASIA grade. The mean bone graft fusion time was 5.15 ± 1.13 months. Three complications occurred, and all were cured after active treatment. Conclusions Nonstructural bone grafts may achieve satisfactory clinical efficacy for appropriately selected patients with lumbar TB.

Abstract Background Postpartum hemorrhage (PPH) is one of the leading causes of maternal mortality and morbidity worldwide. It is believed that hemostatic imbalance secondary to release of tissue plasminogen activator (tPA) and subsequent hyperfibrinolysis plays a major role in PPH pathogenesis. Antifibrinolytic drugs such as tranexamic acid (TXA) are widely used in hemorrhagic conditions associated with hyperfibrinolysis. TXA reduced maternal death due to PPH and its use as a part of PPH treatment is recommended, and in recent years, a number of trials have investigated the efficacy of prophylactic use of TXA in reducing the incidence and the severity of PPH. The study is aiming to assess the efficacy of tranexamic acid in reducing blood loss throughout and after the lower segment cesarean section and reducing the risk of postpartum hemorrhage. Results The amount of blood loss was significantly lower in the study group than the control group (416.12±89.95 and 688.68±134.77 respectively). Also the 24-h postoperative hemoglobin was significantly higher in the study group (11.66±0.79 mg/dl) compared to the control group (10.53±1.07mg/dl), and the 24-h postoperative hematocrit value was significantly higher in the study group (34.99±2.40) compared to control (31.62±3.22). Conclusion Prophylactic administration of tranexamic acid reduces intraoperative and postoperative bleeding in cesarean section and the incidence of postpartum hemorrhage.

Abstract Objectives This study was designed to evaluate the safety and effectiveness of a two-hand technique combining harmonic scalpel (HS) and laparoscopic Peng’s multifunction operative dissector (LPMOD) in patients who underwent laparoscopic hemihepatectomy (LHH). Methods We designed and conducted a case-control study nested in a prospectively collected laparoscopic liver surgery database. Patients who underwent LHH for liver parenchyma transection using HS + LPMOD were defined as cases (n = 98) and LPMOD only as controls (n = 47) from January 2016 to May 2018. Propensity score matching (1:1) between the case and control groups was used in the analyses. Results The case group had significantly less intraoperative blood loss in milliliters (169.4 ± 133.5 vs. 221.5 ± 176.3, P = 0.03) and shorter operative time in minutes (210.5 ± 56.1 vs. 265.7 ± 67.1, P = 0.02) comparing to the control group. The conversion to laparotomy, postoperative hospital stay, resection margin, the mean peak level of postoperative liver function parameters, bile leakage rate, and others were comparable between the two groups. There was no perioperative mortality. Conclusions We demonstrated that the two-handed technique combing HS and LPMOD in LHH is safe and effective which is associated with shorter operative time and less intraoperative blood loss compared with LPMOD alone. The technique facilitates laparoscopic liver resection and is recommended for use.

Abstract Purpose New energy-based sutureless vessel ligation devices, such as the Thunderbeat (Olympus Medical Systems Corp., Tokyo, Japan), could reduce operative time and limit blood loss in head and neck surgery; however, efficacy and safety in major head and neck surgery have not been investigated in a prospective, randomized study. Methods This prospective, double-arm, randomized controlled trial consisted of two parts: total laryngectomy (TL) and neck dissection (ND). Thirty patients planned for TL were randomized in two groups. For the ND part, forty-two operative sides were likewise randomized. In both parts, Thunderbeat was used in addition to the standard instrumentation in the intervention groups, while only standard instrumentation was used in the control groups. Primary outcome values were blood loss, operative time and complication rate. Results For the TL part there was no difference in mean blood loss (p = 0.062), operative time (p = 0.512) and complications (p = 0.662) between both hemostatic techniques. For the neck dissection part, there was a reduction in blood loss (mean 210 mL versus 431 mL, p = 0.046) and in operative time (median 101 (IQR 85–130) minutes versus 150 (IQR 130–199) minutes, p = 0.014) when Thunderbeat was used. There was no difference in complication rate between both hemostatic systems (p = 0.261). Conclusion The Thunderbeat hemostatic device significantly reduces operative blood loss and operative time for neck dissections, without increase in complications. In TL, blood loss using Thunderbeat was comparable with the standard technique, but the operative time tended to be shorter.
