66 ± 0.6919 with limits of agreement being -2.02 to 0.6936. Bland-Altman plot for cardiac output between cTD and NICaS™ showed a mean bias of -1.0386 ± 1.17 with limits of agreement being -3.34 to + 1.26. Percentage error for cardiac index and cardiac output were 64.78% and 64% respectively. Polar plot analysis showed an angular bias of 6.32° with radial limits of agreement being -8.114° to 20.75° for cardiac index and angular bias of 5.6682° with radial limits of agreement being -9.1422° to 20.4784° for cardiac output. Conclusion NICaS™ demonstrated a good trending ability for both CI and CO. However, NICaS™ derived parameters are not interchangeable with the values derived from continuous thermodilution technique.Background Upper thoracic epidural analgesia (TEA) is compared with lower thoracic epidural analgesia for the perioperative pain management and fast tracking in patients undergoing off pump coronary artery bypass grafting (OPCAB) surgery for the intraoperative hemodynamic, quality of analgesia, incentive spirometry, time to awakening & extubation and intensive care unit (ICU) duration. Materials and Methods A prospective, randomized comparative clinical study was conducted with total of 60 patients randomized to either Group U Upper TEA (n = 30) or Group L Lower TEA (n = 30). Visual analog scale (VAS) was recorded in both the groups during rest and deep breathing at the various time intervals postextubation. Both the groups were also compared for intraoperative hemodynamics, incentive spirometry, time to awakening, and extubation and ICU duration. Statistical analysis was performed using the independent Student’s t-test. A value of P less then 0.05 was considered statistically significant. Results Postextubation VAS score at rest and deep breathing at 0, 3, 6, 12, 24, 36, and 48 h were statistically significant in both groups (P ≤ 0.05). Incentive spirometry, time to awakening and extubation and duration of ICU stay were also statistically significant (P ≤ 0.05) between the groups. Conclusion Lower thoracic epidural was better than upper thoracic epidural in perioperative pain management and fast tracking in OPCAB surgery.Background Opioids are traditionally used as the drug of choice for the management of postoperative pain. However, their use is limited in patients undergoing Video-assisted thoracic surgery (VATS), due to their side effects, such as respiratory depression, nausea, and vomiting. Aim In this double-blind active-controlled randomized study, we have compared the analgesic effects of ketorolac and paracetamol to morphine. Methods Patients were randomly chosen from a pool of candidates who were undergoing VATS and were divided into three groups. During the first 24 h postsurgery, patients in the control group received a cumulative dose of morphine 20 mg, while patients in two treatment groups received ketorolac 120 mg and paracetamol 4 g in total. Doses were administered as bolus immediately after surgery and infusion during the first 24 h. Patients’ pain severity was evaluated by visual analogue scale rating (VAS) at rest and during coughing episodes. Results The average pain score at recovery time was 2.29 ± 2.13 and 2.26 ± 2.16 for ketorolac and paracetamol, respectively, and it was significantly lower than the morphine group with an average pain score of 3.87 (P = 0.003). Additionally, the VAS score during cough episodes was significantly higher in the control group throughout the study period compared to study groups. Comparison of mean morphine dose utilized as liberation analgesic (in case of patients had VAS >3) between three groups was not significantly different (P = 0.17). Conclusion Our study demonstrates the non-inferiority of ketorolac and paracetamol to morphine in controlling post-VATS pain without causing any significant side effects. We also show that ketorolac and paracetamol are superior to morphine in controlling pain during 2 h postsurgery.Background Left stellate ganglion blockade (LSGB) may have additive effect to topical administration of papaverine on prevention of vasospasm of left internal thoracic artery (LITA). EHop016 Aims This study aims to compare LITA blood flow with topical application of papaverine alone or in combination with LSGB. Setting Tertiary care hospital. Design Prospective randomized controlled study. Materials and Methods A total of 100 patients operated for coronary revascularization were randomly and equally allocated into two groups. In control Group-C, papaverine was applied topically during the dissection of LITA. In Group-S, the additional LSGB was performed. Blood flow was measured from cut end of the LITA for 15 s. Primary objectives of the evaluation were to observe differences in the LITA blood flow. Observing incidence of radial-femoral arterial pressure difference after cardiopulmonary bypass (CPB) was secondary objective. Statistical Analysis Student’s unpaired t-test and Fisher’s exact test to find out a significant difference between the groups. Results LITA flow in Group-S was insignificantly more (49.28 ± 7.88 ml/min) than Group-C (47.12 ± 7.24 ml/min), (P = 0.15). Radio-femoral arterial pressure difference remained low for 40 min after termination of CPB in the Group-S compared to the Group-C (-0.99 ± 1.85 vs. -1.92 ± 2.26). Conclusion Combining LSGB with papaverine does not increase the LITA blood flow compared to when the papaverine is used alone. However, ganglion blockade reduces radial-femoral arterial pressure difference after CPB. Blockade can be achieved successfully under the ultrasound guidance without any complications.Background Pectoral nerve (PECS1) block has been used for patients undergoing cardiac implantable electronic device (CIED) insertions, however, PECS1 block alone may lead to inadequate analgesia during tunneling and pocket creation because of the highly innervated chest wall. Transversus thoracis muscle plane (TTM) block targeting the anterior branches of T2-T6 intercostal nerves can be effectively used in combination with PECS1 for patients undergoing CIED insertion. The present study hypothesized that combined PECS1 and TTM blocks would provide effective analgesia for patients undergoing CIED insertion compared to PECS1 block alone. Materials and Methods Thirty adult patients between the age group of 18-85 years undergoing CIED insertion were enrolled in the study. A prospective, randomized, comparative, pilot study was conducted. A total of 30 patients were enrolled, who were randomized to either Group P PECS1 block (n = 15) or Group PT PECS1 and TTM blocks (n = 15). The intraoperative requirement of midazolam and local anesthetic and level of sedation by Ramsay sedation score were noted.
