A prospective, randomized, double-blind study was carried out to evaluate two prophylactic regimes in patients undergoing cardiac surgery with cardiopulmonary bypass. Antibiotic plasma levels were measured in fifty consecutive adult patients undergoing valve and coronary surgery. They were divided into two comparable groups of 25 patients, each matched in age, sex, type of operation and duration of cardiopulmonary bypass. Group 1 received 1 g of cephradine with the anaesthetic premedication, 1 g in the prime of the oxygenator and 1 g every six hours during the first 72 hours of the postoperative course. Group 2 received cefazolin following the same protocol except that they received 1 g every eight hours during the postoperative course. There were no allergic or toxic reactions and no infections up to two months follow-up in both groups. Antibiotic plasma levels were significantly higher (p < 0·001) in the cefazolin group in four out of five sampling periods. Antibiotic plasma levels for group 1 versus group 2 were as follows: initial level 11·7 ± 5.2 mcg/ml vs 31 4 ± 35·4 mcg/ml. During cardiopulmonary bypass 26·6 ± 9·5 mcg/ml vs 51·7 ± 21 ·1 mcg/ml. Final levels 13·6 ± 7·0 mcg/ml vs 32·2 ± 17·8 mcg/ml. Baseline levels 2·7 ± 2·3 mcg/ml vs 6·· ± 7·7 mcg/ml and peak level 44·0 ± 16·2 mcg/ml vs 51·2 ± 23·4 mcg/ml (NS). The results of this study demonstrate that cefazolin achieved significantly higher plasma levels during the different phases of the operation and early postoperative period. Also, cefazolin and cephradine levels are above the minimal inhibitory concentrations for the gram positive and gram negative susceptible bacteria, except for the basal levels obtained by cephradine. The favourable pharmacokinetic characteristics of cefazolin, makes it a good choice for prophylactic use during cardiac surgery.

Introduction. Pain after cardiac surgery affects long-term patient wellness. This study investigated the effect of preoperative pregabalin on acute and chronic pain after elective cardiac surgery with median sternotomy. Methods. Prospective double blind study. 93 cardiac surgery patients were randomly assigned into three groups: Group 1 received placebo, Group 2 received oral pregabalin 75 mg, and Group 3 received oral pregabalin 150 mg. Data were collected 8 hours, 24 hours, and 3 months postoperatively. Results. Patients receiving pregabalin required fewer morphine boluses (10 in controls versus 6 in Group 1 versus 4 in Group 2, p=0.000) and had lower pain scores at 8 hours (4 versus 3 versus 3, p=0.001) and 3 months (3 versus 2 versus 2, p=0.000) and lower morphine consumption at 8 hours (14 versus 13 versus 12 mg, p=0.000) and 24 hours (19.5 versus 16 versus 15 mg, p=0.000). Percentage of patients with sleep disturbances or requiring analgesics was lower in the pregabalin group and even lower with higher pregabalin dose (16/31 versus 5/31 versus 3/31, p=0.000, and 26/31 versus 16/31 versus 10/31, p=0.000, resp.) 3 months after surgery. Conclusion. Preoperative oral pregabalin 75 or 150 mg reduces postoperative morphine requirements and acute and chronic pain after cardiac surgery.

Objective: Silicone gel has been shown effective in improving healing post-sternotomy scars. It remains to be determined whether adding herbal extracts to the gel would augment the healing effect. Method: After median sternotomy, patients were randomised into two groups. Group 1: topical silicone gel plus herbal extract gel (Allium cepa, Centella Asiatica, Aloe vera and Paper Mulberry) and Group 2: silicone gel. Patients were treated for six months. The postoperative scars were assessed at three and six months by plastic surgeons using the Vancouver Scar Scale (VSS) and the patient assessment scar scale. Results: Each group comprised 23 patients (n=46 in total). The VSS was significantly lower in Group 1 than in Group 2 (p=0.018 and p=0.051, respectively). In Group 1, the four differences from baseline were vascularity scores at three and six months (–0.391, p=0.025; –0.435, p=0.013, respectively), and pigmentation scores at three and six months (–0.391, p=0.019; –0.609, p=0.000, respectively). In Group 2, differences from baseline were the pigmentation and vascularity score at six months (–0.6609, p=0.000; –0.348, p=0.046, respectively). Conclusion: Our results suggest, post-sternotomy scars trend to have better vascularity and pigmentation when treated with silicone gel plus herbal extracts.

Background: The primary objective of this study was to test and compare the efficacy of currently available intraoperative blood salvage systems via a demonstration of the level of increase in percentage concentration of red blood cells (RBC), white blood cells 9WBC) and platelets (Plt) in the end product. Methods: In a prospective, randomized study, data of 80 patients undergoing elective cardiac surgery with cardiopulmonary bypass in a 6-month period was collected, of which the volume aspirated from the surgical field was processed by either the HemoSep Novel Collection Bag (Advancis Surgical, Kirkby-in-Ashfield, Notts, UK) (N=40) (Group 1) or a cell- saver (C.A.T.S Plus Autotransfusion System, Fresenius Kabi, Bad Homburg, Germany) (N=40) (Group 2). Results: Hematocrit levels increased from 23.05%±2.7 to 43.02%±12 in Group 1 and from 24.5±2 up to 55.2±9 in Group 2 (p=0.013). The mean number of platelets rose to 225200±47000 from 116400 ±40000 in the HemoSep and decreased from 125200±25000 to 96500±30000 in the cell-saver group (p=0.00001). The leukocyte count was concentrated significantly better in Group 1 (from 10100±4300 to 18120±7000; p=0.001). IL-6 levels (pg/dL) decreased from 223±47 to 83±21 in Group 1 and from 219±40 to 200±40 in Group 2 (p=0.001). Fibrinogen was protected significantly better in the HemoSep group (from 185±35 to 455±45; p=0.004). Conclusions: Intraoperative blood salvage systems functioned properly and the resultant blood product was superior in terms of red blood cell species. The HemoSep group had significantly better platelet and leukocyte concentrations and fibrinogen content.

The desired use of the HPH Jr. is optimal due to the low priming volume; however, the lower rate of volume removal necessitates utilization of a larger hemofilter. Larger hemofilters carry a higher prime volume, which is impactful in the pediatric setting. Pediatric cardiac surgery patients under 18 kilograms requiring cardiopulmonary bypass were randomly assigned to one of two study groups. Group 1 (coated) contained an HPH Jr. hemofilter that was primed with the addition of 25% albumin and heparin. Group 2 (non-coated) contained an HPH Jr. hemofilter that was primed with only Normosol-R®. After cardioplegia delivery, zero balance ultrafiltration (ZBUF) was initiated and maintained for thirty consecutive minutes. The flow through the hemofilter was standardized at 70 ml/min and the vacuum applied to the effluent line was set at -150 mmHg. Effluent fluid removal was measured at the termination of thirty minutes and compared between the groups. Group comparisons between the coated vs non-coated hemofilter groups were assessed using two-sample t-tests or the Mann-Whitney U test, when appropriate. Forty-two patients were included in the analysis. There were 22 patients who had the non-coated hemofilter and 20 patients with a coated hemofilter. The differences between the two groups are illustrated in Table 1. There was a statistically significant higher ultrafiltration volume with the coated hemofilter group (p=0.008) (Figure 1). These results illustrate the improved efficiency of the HPH Jr. with the addition of 25% albumin and heparin during the priming process.

Background and Aim: Pneumoperitoneum (PP) for laparoscopic surgery is known to induce a pressor response. It can be attenuated by drugs, like opioids, vasodilators, beta blocking agents and alpha-2 agonists, but these drugs have their side effects. This study investigated the efficacy of magnesium sulphate to attenuate hemodynamic response associated with pneumoperitoneum in patients undergoing laparoscopic cholecystectomy.Methodology: This randomized, double blind, prospective study was carried out at Department of Anesthesiology, Maharishi Markandeshwar University, Mullana, Haryana (India). A total of 60 patients of ASA grade I or II, aged 20-60 y, of either sex, undergoing laparoscopic cholecystectomy, were randomly allocated into one of the two groups of 30 each. Standardized general anesthesia was administered to all patients. Group 1 patients received magnesium sulphate (30 mg/kg) intravenously as a bolus before induction of PP and Group 2 patients received same volume of 0.9% normal saline. Hemodynamic variables, e.g. heart rate (HR), systolic (SBP), diastolic (DBP), mean arterial pressures (MAP) were recorded from the start of surgery till extubation. Statistical analysis: SPSS version 17.0 for windows was used and p value of < 0.05 was considered significant.Results: Mean HR was 81.50 ± 8.44 vs. 93.03 ± 6.93/min, SBP was 126.37 ± 13.03 vs. 150.20 ± 10.45 mmHg, DBP was 82.50 ± 11.20 vs. 94.73 ± 8.33 mmHg, and MAP 98.43 ± 10.29 vs.113.27 ± 9.16 mmHg in Group 1 and Group 2, respectively, at 10 min after PP. Statistically significant fall in HR, SBP, DBP, MAP was seen in Group 1 at 10 min after PP till extubation. (p < 0.05).Conclusion: Intravenous magnesium sulphate effectively attenuates the hemodynamic response to pneumoperitoneum in laparoscopic cholecystectomy under general anesthesia.Citation: Bansal K, Santpur MU, Garg U, Goel K, Vijay D, Tatineni Bansal.

BackgroundPostoperative pain after pediatric cardiac surgery is usually treated with intravenous opioids. Recently, the focus has been on postoperative regional analgesia with the introduction of ultrasound-guided erector spinae plane blocks (ESPBs). We hypothesized that bilateral ESPB with a programmed intermittent bolus (PIB) regimen decreases postoperative morphine consumption at 48 hours and improves analgesia in children who undergo cardiac surgery.MethodsThis randomized, double-blind, placebo-controlled study comprised 50 children who underwent cardiac surgery through midline sternotomy. The patients were allocated randomly into two groups: ultrasound-guided bilateral ESPB at the level of T3–T4 transverse process then PIB with saline infusion (group 1, n=23) or PIB with 0.2% ropivacaine (group 2, n=27). Intravenous morphine at 30 µg/kg/hour was used as rescue analgesia. Postoperative pain was assessed using the COMFORT-B score for extubation, drain removal, and mobilization, and the FLACC (Face, Legs, Activity, Cry, Consolability) scale at 0, 2, 4, 6, 8, 12, 16, 20, 24, 36, and 48 hours after surgery. Adverse events were noted.ResultsThe total dose of morphine in 48 hours was significantly decreased in patients receiving a bilateral ESPB with ropivacaine (120±320 µg/kg) compared with patients with saline infusion (512±560 µg/kg; p=0.03). Fourteen per cent of patients required rescue analgesia with morphine in group 2 compared with 41% in group 1 (p=0.05). The patients in group 2 demonstrated significantly reduced COMFORT-B scores at extubation, drain removal, and mobilization compared with those in group 1 and had reduced FLACC scale levels at 20 and 24 hours postoperatively (p=0.05 and p=0.001, respectively). No differences were reported for extubation and drain removal times or for length of hospital stay. In addition, vomiting episodes were decreased in group 2 (p=0.01).ConclusionsIn pediatric cardiac surgery, the results of this study confirm our hypothesis that bilateral ESPB analgesia with ropivacaine decreases the postoperative morphine consumption at 48 hours and demonstrates better postoperative analgesia compared with a control group.Trial registration numberNCT03593642.

Abstract Significant decreases in magnesium (Mg) concentration and alkaline phosphatase (ALP, EC 3.1.3.1) activity in serum were seen in patients after cardiac surgery with cardiopulmonary bypass (Group 1), as compared with non-cardiac-surgery patients after general anesthesia (Group 2) or only spinal anesthesia (Group 3). Mean changes for Mg and ALP by the first postoperative day, compared with pre-operative baseline values, were as follows: Group 1: Mg -7.5 mg/L (-38.3%), ALP -46U/L (-48.4%); Group 2: Mg -3.3 mg/L (-17.4%), ALP -17 U/L (-16.5%); and Group 3: Mg -1.9 mg/L (-10.0%), ALP -15 U/L (-14.0%). The decreases in Mg and ALP observed in post-cardiac-surgery patients appear to be a consequence of the cardiac surgery and the cardiopulmonary bypass pump. Measurement of Mg and ALP in a subgroup of 10 cardiac-surgery patients for 10 days postoperatively showed initial decreases, with gradual recovery to near-normal values by the 10th day. That the changes in Mg and ALP seen postoperatively were not attributable to hemodilution alone was confirmed by measuring total-protein concentrations before and after operation. ALP requires Mg ion in vitro for optimal activity, but addition of Mg in the appropriate amounts to sera with low ALP activity did not restore ALP activity. The low ALP activity seen in post-cardiac surgery patients in vivo may perhaps be related to factors other than Mg that were removed by the cardiopulmonary bypass pump.

Objective: To study multinodular goitre patients’ surgery by direct observation of surgical technique, and to compare complications with surgeons’ skills and experience, for improved training of future thyroid surgeons. Methods: Based on positivist epistemology and analytical observational design, this prospective double-blind study of a cohort of multinodular goitre patients operated upon by variedly experienced surgeons, was conducted at Bahawal Victoria Hospital Bahawalpur and Nishtar Medical University Hospital Multan, Pakistan, from December 2016 to April 2019. Patients were admitted through outpatient department and operated upon in routine operation lists. The surgeons were specialists/senior registrars, assistant professors, associate professors and professors. The patients were divided into two virtual groups: the one operated upon by surgeons with >3 years of post-fellowship experience and the other operated upon by surgeons with <3 years of post-fellowship experience. Surgeries were directly observed and differences in surgical technique and complications were recorded for respective groups. Data was analysed using SPSS 20. Results: Of the 134 patients, there were 73(54.5%) in group 1 and 61(45.5%) in group 2. Overall, there were 119(88.8%) females and 15(11.2%) males. The overall mean age was 37.17+/-13.41 years (range: 14-80 years). Of the 25 surgeons, 13(52%) were in group 1 and 12(48%) in group 2. Group 1 had fewer complications compared to group 2, which on certain parameters was statistically significant (p<0.05). Conclusion: Surgeons’ experience and technique were found to have significant relationship with the rate of complications. Direct observation of surgeries is significant for real life evaluation and training of junior surgeons.
