The effect of different doses of chloroprocaine 1% for low dose saddle anaesthesia in outpatient perianal surgery: A prospective randomized study

The present study was designed to investigate saddle anesthesia with different doses of chloroprocaine at the same concentration (0.5%, w/v) in terms of extent of sensory and motor block, recovery from block, time for ambulation and time for urinary voiding. The study was conducted in the department of Anaesthesiology of a tertiary healthcare centre of southern Rajasthan. 120 patients of either sex, aged between 20-50 years, with American Society of Anaesthesiologists grade I/II scheduled for elective perianal surgery in lithotomy position (duration < 40 minutes), were enrolled in the study. The patients were divided into three groups (n=40/group), receiving either 10mg, 15mg or 20mg of 1% 2-chloroprocaine in saddle anaesthesia. The effect was noted and compared in terms of extent of sensory and motor block, recovery from block, time for ambulation and time for urinary voiding. All the three groups were comparable with no statistical difference in terms of age, weight, height, BMI, ASA grading and site of injection among the participants of the groups. Number of patients who were able to move from stretcher to operation table and again from operation table to stretcher without help did not differ significantly among all the three groups. Similarly, there was no statistically significant difference in pre operative and post operative Bromage scores of participants among three groups (p value > 0.05). There was significant difference in the number of anaesthetized dermatomes both pre and post operatively among all the three groups (p value <0.001). Duration of surgery did not differ significantly among the three groups. There was also significant diference in the time for unassisted ambulation post operatively and time for urinary voiding among the three groups (p value < 0.001). 10 mg chloroprocaine may cause early post operative pain while 30 mg dose may cause delayed unassisted ambulation and urinary voiding postoperatively so 15 mg dose can be used as minimum optimal dose for saddle anaesthesia for ultra-short perianal procedures.

Different Doses

Background: Though, various studies have been conducted to show the efficacy of dexmedetomidine as an adjuvant to brachial plexus block, there is no clear consensus for its optimal dose. We compared 2 different doses of dexmedetomidine (1mcg/kg Vs 2mcg/kg) with ropivaciane in USG guided brachial plexus block for the quality of anesthesia and analgesia. Materials and Methods: Fifty patients (18-50years, 50-60kgs), ASA PS I and II undergoing surgery of upper limb were enrolled in this prospective, double blind, randomized control trial. Group Rd received 19ml of 0.5% Ropivaciane with 1mcg/kg of dexmedetomidine (total 20ml), and Group RD received 19ml of 0.5% Ropivacaine with 2mcg/kg of dexmedetomidine (total 20ml). Onset and duration of sensory and motor block, duration of analgesia, sedation score, hemodyanamic changes were compared. We also monitored for various un towards effects. Results: The onset time of sensory and motor block (9.36±1.114 mins and 14.40 ± 1.528 mins in group Rd vs 8.32 ±0.945 mins and 12.40 ± 1.21 mins in group RD) were not significantly different between two groups (p-value > 0.05).The duration of sensory and motor block (596.20 ± 76.859 mins and 541.20±81.564 mins in group Rd vs 730.80 + 65.187 mins and 659.80±93.607 mins in group RD) were not significantly longer in group RD than group Rd (p-value > 0.05). The duration of analgesia (626.00±70.475 mins in group Rd vs 754.00±60.139 mins in group RD) were not significantly longer in group RD than group Rd (p-value > 0.05). Hemodynamic parameters were also comparable between two groups (p-value >0.05) but 3 patients in RD group (2mcg/kg) developed bradycardia and required treatment with atropine whereas in Rd group (1mcg/kg) none developed bradycardia. Conclusions: There is no significant difference in the onset and duration of block between the two groups. However, higher dose of dexmedetomidine is associated bradycardia. Hence, in comparision with 2mcg/kg, 1mcg/kg of dexmedetomidine is better adjuvant to 0.5% ropivaciane in terms of safety and effectiveness.Keywords: dexmedetomidine; ropivacaine; supraclavicular brachial plexus block.

2619 Background: Vaccination with the intracellular domain (ICD) of HER2 in pre-clinical models is both immunogenic and protective against the development of mammary tumors. This study (NCT00436254) was designed to examine the safety and optimal immunogenic dose of a DNA-based vaccine encoding the HER2 ICD in subjects with HER2+ breast cancer. Methods: Sixty-six patients with stage III or IV HER2 + breast cancer in remission or with stable bone only disease were enrolled into three vaccine arms: 1 (10mcg dose of plasmid), 2 (100mcg) and 3 (500mcg). Vaccines were administered i.d. monthly for three immunizations. Endpoints included safety and optimal dose. HER2 specific IFN-gamma immune responses were evaluated and DNA persistence at the vaccine site was assessed. Toxicity and clinical outcomes were followed for 10 years. Results: The majority of vaccine-related toxicity was grade 1 (89%) and grade 2 (11%) and was not significantly different between the three dose arms. All Arms developed HER2 ICD immunity after vaccination, however, patients in Arm 2 and Arm 3 had significantly better immune responses (of higher magnitude and at most time points) than patients in Arm 1 (p=0.003 and p<0.001, respectively) after adjusting for baseline factors. At 60 weeks, the number of patients who maintained the greatest fold-difference in HER2 ICD immune responses from their baseline was highest in Arm 2 (73%) when compared to Arm 1 (47%) and Arm 3 (45%). Associations between ICD responses and plasmid DNA persistence at the vaccine site were estimated via linear regression models. HER ICD immunity after the end of immunizations, relative to baseline, was significantly lower in patients with DNA persistence at week 16 compared to those without persistence (p=0.02). Patients at the highest dose demonstrated the greatest incidence of plasmid persistence (92%) as compared to 33% in Arm 1 and 10% in Arm 2. The median time of follow-up was 118.6 months (Arm 1), 99.7 months (Arm 2), and 73.5 months (Arm 3). The median OS and PFS has not been reached in any Arm and did not differ with respect to treatment arm (Log-rank p-value 0.36 for OS, and 0.63 for PFS). However, we observed a separation of Kaplan-Meier curves for OS from about 40 months and curves for PFS from about 30 months, and the separation maintained until the end of the study for Arm 2 versus Arm 1 and Arm 3. One patient in Arm 2 developed lymphocytic colitis 2.2 years from enrollment deemed possibly related to vaccination. Conclusions: An intermediate dose (100mcg) of vaccine was immunogenic and associated with persistence of immunity at 60 weeks. A randomized phase II trial of the HER2 ICD plasmid-based vaccine in the neoadjuvant setting is in development. Clinical trial information: NCT00436254.

Aim: To compare the outcomes in term of complication of Veress Needle Insertion (VNI) to Direct Trocar Insertion (DTI) for creation of pneumoperitoneum in laparoscopic cholecystectomy. Design: Randomized controlled trial Place and Duration of Study: The current analysis was conducted at Khawaja Muhammad Safdar Medical College Surgical Department, Allama Iqbal Memorial Hospital and Govt. Sardar Begum Teaching Hospital, Sialkot from September 27, 2017, to September 26, 2020. Methodology: A total of six hundred and eight (n=608) patients, having age 30 to 75 years planned for laparoscopic cholecystectomy were included in this study. Patients were randomly divided into two groups, Group A (Direct Trocar Insertion), Group B (Veress Needle Insertion). Both groups had age and sex matched males and female. All trocars and veress needle used were disposable, with a safety shield. The primary outcome of our study was to compare the complications to assess the safety levels, while total time taken by the procedure and mean time for laparoscopic entry were the secondary end points. The collected data was analyzed by using software SPSS version 22. Chi-square test was used to check the significance of variance. P-value less than 0.05 remained the statistically significant. Results: The complication rate in VNI group were significantly greater than the DTI group (p < 0.01), the duration of surgery between the two groups was not significantly different (p > 0.05), but we found statistically significant difference in mean laparoscope insertion time (DTI 3.4+ 1.4 versus VNI 4.8+ 0.7 minutes, p < 0.001). Conclusion: From the results of our study, it can be concluded that the direct trocar insertion is a safe alternative to veress needle insertion in laparoscopic cholecystectomy as it is associated with fewer complications.

Introduction: Thyroidectomy is a common surgery in the neck area, in which the application of platysma muscle suture after thyroidectomy is still being discussed. This study was conducted to compare the application (currently common) or non-application of suture for platysma muscle. Methods: In this retrospective cross-sectional study, 117 patients underwent thyroidectomy, among which 63 cases without suturing platysma (control group) and 54 subjects with suturing platysma (Intervention group ) were examined in terms of postoperative pain based on visual analogue scale score measured 24 h post-operation. The samples were also investigated regarding hematoma and seroma, wound infection, length of hospitalization, scarring (1 year after surgery), duration of surgery, and the number of cases using opioids during the hospitalization. Patients with diabetes, previous neck surgery, coagulopathy, and radiation history were excluded from the study. The gathered data were analyzed statistically in SPSS software (version 18) using the Chi-square test and the Mann–Whitney U test. A p-value of less than (0.05) was considered significant. Results: Based on the findings, the mean age of the patients in the Intervention group was calculated at 51 years, of which 41 and 13 cases were females and males, respectively. In the Intervention group, 34 patients underwent complete thyroidectomy and 20 patients had hemithyroidectomy. The mean age score of subjects in the control group was calculated at 50 years, of which 44 and 19 patients were respectively female and male. No significant difference was revealed considering wound infection, length of hospitalization, created scarring, the amount of opioid use (opioids), and postoperative pain. However, only the length of surgery was different between the groups (P-value<0.05). Conclusions: There was no difference between wound and surgical complications and cosmetic results between both groups; nevertheless, due to the duration of the surgery and other benefits, such as consuming less thread, not suturing the platysma is recommended.

Background: Various studies have shown the effects of morbid obesity on the adverse consequences of various surgeries, especially postoperative infections. However, some studies have shown that the complications of spinal surgery in obese and non-obese patients are not significantly different. Objectives: This study investigated and compared the duration of surgery, length of hospital stay, and complications after common spinal surgeries by orthopedic spine fellowship in obese and non-obese patients in a specialized spine center in Iran. Methods: All patients who underwent decompression with or without lumbar fusion were included in this retrospective study. These patients were classified into two groups: non-obese (BMI <30 kg/m2) and obese (BMI ≥30 kg/m2). The data related to type and levels of surgery, 30-day hospital complications, length of hospital stay, rate of postoperative wound infection, blood loss, and need for transfusion were all extracted and compared between the two groups. Results: A total of 148 patients (74%) were in the non-obese group and 52 patients (26%) in the obese group. The number of patients that need packed cells was significantly higher in the obese group (51.8% vs 32.6%) (P=0.01). Otherwise, there were not a significant difference between type of treatment (fusion or only decompression) (P=0.78), interbody fusion (P=0.26), osteotomy (P=0.56), duration of surgery (P=0.25), length of hospital stay (P=0.72), mean amount of blood loss (P=0.09), and postoperative complications (P=0.68) between the two groups. Conclusion: Our results suggest that duration of surgery, length of hospital stay, and postoperative complications are not associated with the BMI of the patients.

Background: Intravenous (IV) sulfamethoxazole/trimethoprim (SMX/TMP) has been associated with hyponatremia in adults. Objective: The primary objective was to identify the number of patients with a serum sodium <135 mEq/L. Secondary objectives between the hyponatremic versus nonhyponatremic groups included demographic comparisons, median serum sodium concentrations, SMX/TMP cumulative dose, number of diuretics, and other medications causing hyponatremia. Methods: This was a retrospective study of children <18 years receiving IV SMP/TMX. Comparisons were conducted via Mann-Whitney-Wilcoxon and Mantel-Haenszel χ2 tests with an a priori P value <0.05. Results: Sixty-one patients received 66 total courses; 20 courses (30.3%) were associated with hyponatremia with a decrease in the median nadir serum sodium concentration of 133 and 138 mEq/L in the hyponatremic and nonhyponatremic groups, respectively ( P<0.001). The median age (interquartile range) was lower in the hyponatremic versus nonhyponatremic group, but this was not statistically significant: 0.6 (0.1-5.5) versus 3.9 (0.3-11.0) years; P=0.077. There was no significant difference in the median cumulative dose (mg/kg) between groups; P=0.104. In addition, there was a significant difference in the number of children in the hyponatremic versus nonhyponatremic groups receiving diuretics (16 [80.0%] vs 23 [50.0%], P=0.023) and other medications that cause hyponatremia (7 [35.0%] vs 5 [10.9%], P=0.034), respectively. Furosemide was noted to be the medication most associated with hyponatremia. Conclusion and Relevance: Approximately one-third administered IV SMX/TMP developed hyponatremia. Concomitant furosemide administration was one of the most common risk factors. Clinicians should be aware of this potential adverse event when initiating IV SMX/TMP in children.

Main Target

In this study we compared the efficacy of 1000 mg phenazone with that of placebo in the treatment of acute migraine attacks in a randomized double-blind, placebo-controlled study of 208 patients. The main target criterion was the number of patients with a pain reduction from severe or moderate to slight or no pain 2 h after taking the pain medication. The percentage of patients satisfying the main target criterion was 48.6% for phenazone and 27.2% ( P < 0.05) for placebo. Freedom from pain after 2 h was reported by 27.6% with phenazone treatment and 13.6% ( P < 0.05) with placebo. Compared with placebo, the phenazone treatment also resulted in a significant improvement in the associated migraine symptoms of nausea, phonophobia and photophobia. Of patients treated with phenazone 11.4%, and 5.8% of those treated with placebo reported adverse events. There was no significant difference between the groups with regard to numbers of patients with adverse events. No serious adverse events occurred. The results show that phenazone at a dosage of 1000 mg is effective and well tolerated in the treatment of acute migraine attacks.

Category: Ankle Arthritis Introduction/Purpose: The number of total ankle arthroplasties (TAA) is on the rise. Complications associated with TAA include need for blood transfusion, deep vein thrombosis, hematoma, infection, and wound complications. Tranexamic acid (TXA) use in the total knee and total hip population has been found to decrease the rate of blood transfusion. The rate of infections and blood transfusions in TAA was reported to be 3.2% and 1.3%, respectively. In calcaneal fractures TXA was found to decrease wound complications. Our goal was to evaluate the use of TXA in the TAA population to see if its use decreases blood loss or wound complications. Methods: This is a retrospective review of two patient cohorts operated on by a single surgeon from 2010 to 2016. We compared a group of TAA patients that did not receive TXA versus a subsequent group that received TXA. Patients received 1 g IV TXA before tourniquet was inflated and another 1 g following the release of the tourniquet. Pre-operative hemoglobin and hematocrit levels were compared to postoperative levels. Post-operative complications were compared between the two groups. Results: 87 patients were included in the study. 35 patients (40%) received TXA. In patients that received TXA, 18 had postoperative hemoglobin levels available. These patients were compared to a control cohort of 52 patients that did not receive TXA. No significant difference existed between the two groups in gender or age (p=0.9; p=0.7 respectively). Mean estimated blood loss was the same between the two groups. Overall postoperative complications, including wound complications, were higher in the TXA group at 26% vs 12% but this was not statistically significant (p-value = 0.086). The preoperative to postoperative change in hemoglobin/hematocrit levels was not statistically significant between groups (p-value = 0.78). There was one transfusion required in the non-TXA group and no transfusions required in the TXA group (p=0.9). Conclusion: The use of TXA was not found to provide a beneficial effect in total ankle arthroplasty in either decreasing wound complications or blood loss. Given these results, TXA use might not be cost effective in total ankle arthroplasty as opposed to other total joint arthroplasties. Further higher levels studies with increased number of patients are required to further evaluate TXA effectiveness in TAA.

Preanesthetic Medication

Introduction: Anxiety in children undergoing surgery is characterized by subjective feeling of tension, apprehension,nervousness and worry that may be expressed in various forms. Clonidine, an alpha 2-adrenoceptor agonist, has beenshown to be as a preanesthetic medication in childrens. The current study was designed to investigate the differencesof level sedation clonidine syrup and diazepam syrup as a premedicant in children.Methods: In a randomized, double-blind, controlled clinical trial, 40 children, aged 2-12 yr, undergoing electivesurgery received 2 micrograms/kg clonidine syrup or 0.4 mg/kg diazepam syrup orally. These agents were administered120 min before the estimated time of induction of general anesthesia and noted the children’s level of sedation. Thelevel of sedation were compared among the two groups. PASS <1 demanded rescue intravenous sedation.Result: Clonidine syrup 2 mcg/kgBB provided better quality of sedation after 60 min of premedicant but it wasn’tsignificant(1.8±0.92) and diazepam syrup (0.80±0.89; p>0.05) and number of patients with rescue intravenous diazepamacceptance were same both clonidine group compared to diazepam, there was no significant difference between twogroups, 10% of clonidine group patients, 10 % of diazepam group patients (p>0.05). No clinically significanthypotension or bradycardia was observed after preanesthetic medications of diazepam and clonidine syrup.Discussion: These data indicate that, even in pediatric surgery, the 2 micrograms/kg syrup clonidine is an effectivepremedication. However, the safety and optimal dose of clonidine in this setting remain to be determined.
