Pregnancy in Eisenmenger syndrome: a case series from a tertiary care hospital of Northern India.

BACKGROUND: Despite advances in medical care, we still come across pregnancy in Eisenmenger syndrome. Eisenmenger syndrome represents the severe end of the spectrum for disease in pulmonary artery hypertension associated with CHD. Due to very high maternal and perinatal morbidity and mortality, pregnancy is contraindicated among these women. Current guidelines also recommend that the women who become pregnant should opt for early termination of pregnancy. Here, we present a case series of 11 women of Eisenmenger syndrome and their pregnancy outcome. METHODS: It was a retrospective analysis of 12 pregnancies among 11 women with Eisenmenger syndrome who were managed in a tertiary care referral centre of Northern India. RESULTS: The mean age of these women was 28 ± 4 years (range 22 to 36 years). Almost 80% of them (9/11) were diagnosed with Eisenmenger syndrome during pregnancy. The commonest cardiac lesion was Ventricular Septal defect (54.5%) followed by Atrial Septal defect (27.3%) and Patent Ductus arteriosus (9.1%). Only three women opted for medical termination of pregnancy, rest eight continued the pregnancy or presented late. Pregnancy complications found include pre-eclampsia (50%), abruption (22%), and fetal growth retardation (62.5%). There were three maternal deaths (mortality rate 27%) in postpartum period. CONCLUSION: This case series highlights the delay in diagnosis and treatment of CHD despite improvement in medical care. Women with Eisenmenger syndrome require effective contraception, preconceptional counselling, early termination of pregnancy, and multidisciplinary care.

Factors Affecting Time to Emergence From General Anesthesia Following Clipping of Ruptured Aneurysms: A Prospective Observational Study.

INTRODUCTION: Early emergence from anesthesia is valuable, especially among neurosurgical patients for postoperative neurological evaluation and appropriate interventions. However, the factors affecting the emergence in patients undergoing clipping of ruptured aneurysms have not been studied. MATERIALS AND METHODS: This was a prospective observational study on patients of aneurysmal subarachnoid hemorrhage with World Federation of Neurological Surgeons (WFNS) Grades I to III, undergoing surgical clipping. All relevant preoperative and intraoperative details were collected and analyzed to assess the factors affecting emergence time. RESULTS: A total of 67 patients with a median age of 46 years were included in the study. The number of patients with Fisher Grades I, II, III, and IV was 6, 20, 25, and 16, respectively. The median time to emergence was 17 minutes (interquartile range 10-240 minutes). On univariate analysis, the factors that were found to have a significant relationship with time to emergence were preoperative Glasgow Coma Score (GCS; P = 0.02), WFNS grade (P = 0.005, temporary clipping time (P = 0.03), and the temperature at the end of surgery (P < 0.001) In the multivariate analysis using generalized linear model, preinduction GCS (P < 0.001), patient's temperature at the end of surgery (P < 0.001), and temporary clipping time (P = 0.01) had a significant impact on the emergence time, independent of age, American Society of Anesthesiologists grade, Fisher grade, duration of anesthesia and of each other, with GCS and temperature having the maximum impact. ROC curve for temperature had a cutoff value at 35.3°C with an 83% probability of awakening beyond 15 minutes if the temperature decreased below 35.3°C. CONCLUSION: The preinduction GCS, the temperature of patients at the end of surgery, and the duration of temporary clipping have a significant independent impact on the time to emergence from neurosurgical anesthesia, in the order of the strength of the association.

Comparison of Palonosetron and Dexamethasone with Ondansetron and Dexamethasone to Prevent Postoperative Nausea and Vomiting in Patients Undergoing Laparoscopic Cholecystectomy.

BACKGROUND: Laparoscopic cholecystectomy (LC) is associated with high risk of postoperative nausea and vomiting (PONV) if no prophylactic antiemetic is used. AIMS: The study compared prophylactic palonosetron and dexamethasone with ondansetron and dexamethasone in patients undergoing LC. SETTING AND DESIGN: This prospective, double-blinded, randomized, controlled study was conducted at a tertiary care center. MATERIALS AND METHODS: The study was carried out in 86 patients who underwent LC. The patients were randomly assigned to following study groups: Group 1 who received palonosetron (0.75 mg) with dexamethasone (8 mg) and Group II who received ondansetron (4 mg) with dexamethasone (8 mg). Patients were observed for nausea with visual analog scale and vomiting episode during 48 h postoperative follow-up. STATISTICAL ANALYSIS USED: Data were analyzed as mean, standard deviation, percentage, and number. The following statistical tests were used: paired or unpaired t-test, Mann-Whitney test, Chi-square test, and repeated ANOVA test. RESULTS: There was no statistically significant difference in heart rate, mean arterial pressure, and oxygen saturation from baseline. During 48 h follow-up, the incidence of nausea, vomiting, and PONV was higher in Group II, but the difference was not statistically significant. The total dose of rescue antiemetic was 2.14 ± 4.15 mg in Group I and 5.00 ± 8.62 mg in Group II patients (P = 0.058). Headache was present in three patients in Group I and two patients of Group II. CONCLUSION: The palonosetron with dexamethasone is comparable to ondansetron with dexamethasone in the prevention of PONV in patients undergoing LC.

Comparison of Two Supraglottic Airway Devices: I-gel Airway and ProSeal Laryngeal Mask Airway Following Digital Insertion in Nonparalyzed Anesthetized Patients.

AIMS: The study is aimed to compare the efficacy of I-gel and ProSeal laryngeal mask airway (PLMA) in nonparalysed anesthetized individuals following manufacturer-recommended digital insertion. MATERIALS AND METHODS: In this prospective randomized observational study, 40 American Society of Anesthesiologists I and II patients, aged 18-65 years scheduled for elective surgical procedures were allocated either to PLMA group (Group P, n = 20) or the I-gel group (Group I, n = 20). Following digital insertion of PLMA or I-gel, the following parameters were compared: insertion time, ease of insertion, number of attempts, failed insertion, airway reaction during insertion, oropharyngeal leak (OPL) pressure, and gastric insufflation on auscultation. Fiberoptic view of both the channels of the airway devices and ease of insertion of 12 F Ryle's tube through gastric drain channel were graded. Postoperative complications were also noted. RESULTS: First attempt and overall insertion success were similar (PLMA, 85% and 100%; I-gel 80% and 100%, respectively). Mean (standard deviation) insertion times were similar (PLMA, 27.40 [11.51] s; I-gel 25.45 [9.03] s). Mean OPL pressure was 3.5 cm H2O higher with PLMA (P < 0.012). The passage of Ryle's tube was easier through I-gel than PLMA. Grade I glottic view (full view of the vocal cords) was visible in 17 (85%) patients who were managed with I-gel whereas only 9 (45%) patients had Grade I view in the PLMA group. CONCLUSION: The time required for digital insertion of PLMA and I-gel in nonparalyzed anesthetized patients is similar but PLMA forms a better oropharyngeal seal. I-gel is better positioned over the laryngeal framework and esophagus. I-gel allows easier passage of Ryle's tube through its drain channel than PLMA. The incidence and severity of postoperative sore throat and hoarseness was higher with PLMA.

Comparison of serum triglyceride levels with propofol in long chain triglyceride and propofol in medium and long chain triglyceride after short term anesthesia in pediatric patients.

BACKGROUND: Significant increase in serum triglyceride (ST) concentration have been described in adult population after prolonged administration of propofol formulation containing long chain triglyceride (LCT). Though, medium chain triglyceride-LCT (MCT-LCT) propofol when compared with LCT propofol for long-term sedation in adults resulted in identical triglyceride levels, the elimination of triglyceride was faster in patients administered MCT-LCT propofol. MATERIALS AND METHODS: A total of 40 children were randomized into two groups of 20 each; Group I were induced with 1% LCT propofol (3 mg/kg) and Group II with 1% medium and LCT propofol and maintained with descalating dose of 20.15 and 10 mg/kg/h at 10 min intervals. Blood samples for ST concentration were obtained before induction of anesthesia, at the end of propofol infusion and 4 h after terminating propofol infusion. RESULTS: ST levels were raised significantly above the basal values in both the groups but the rise was significantly higher in Group I (P < 0.05). Four hours after stopping propofol infusion the triglyceride levels were similar to the basal values in Group II, whereas in Group I the values were significantly greater than the baseline (P < 0.05) as well as those of Group II (P < 0.05). No clinically significant adverse effect of hypertriglyceridemia was observed. CONCLUSION: Even short term anesthesia with LCT and MCT-LCT propofol (1%) leads to elevated ST levels. The increase in ST levels is less with MCT-LCT propofol and elimination of triglyceride is also rapid after terminating MCT-LCT propofol infusion.

Intraoperative localization and monitoring of migrating foreign body using transesophageal echocardiography.

Radiological imaging is often used for the preoperative localization of foreign body following blast injury, but their utility in case of migration during intra-operative period is limited. Transesophageal echocardiography (TEE) has been used for intra-operative localization and removal of intra-cardiac foreign body; however, reports for localization of extracardiac migrating foreign body are few. Preoperative radiological imaging, in a victim of factory blast-injury, suggested foreign body in the posterior mediastinum. However, the intra-operative TEE showed it in the left atrium, which later migrated into the left ventricle necessitating a change in surgical approach for its removal.

Perioperative predictors of morbidity and mortality following cardiac surgery under cardiopulmonary bypass.

BACKGROUND: Prediction of outcome after cardiac surgery is difficult despite a number of models using pre-, intra- and post-operative factors. Ideally, risk factors operating in all three phases of the patients' stay in the hospital should be incorporated into any outcome prediction model. The aim of the present study was to identify the perioperative risk factors associated with morbidity, mortality and length of stay in the recovery room (LOSR) and length of stay in the hospital (LOSH). METHODS: Eighty-eight adults of either sex, patients undergoing elective open cardiac surgery were studied prospectively. The ability of a number of pre-, intra- and post-operative factors to predict outcome in the form of mortality, immediate morbidity (LOSR) and intermediate morbidity (LOSH) was assessed. RESULTS: Factors associated with higher mortality were preoperative prothrombin index (PTI), American Society of Anesthesiology-Physical Status (ASA-PS) grade, Cardiac Anaesthesia Risk Evaluation (CARE) score and New York Heart Association (NYHA) class, intraoperative duration of cardiopulmonary bypass (DCPB), number of inotropes used while coming off cardiopulmonary bypass and postoperatively, Acute Physiology and Chronic Health Evaluation (APACHE) II excluding the Glassgow Comma Scale (GCS) component and the number of inotropes used. Immediate morbidity was associated with preoperative PTI, inotrope usage intra- and post-operatively and the APACHE score. Intermediate morbidity was associated with DCPB and intra- and post-operative inotrope usage. Individual surgeon influenced the LOSR and the LOSH. CONCLUSION: APACHE score, a general purpose severity of illness score, was relatively ineffective in the postoperative period because of sedation, neuromuscular blockade and elective ventilation used in a number of these patients. The preoperative and intraoperative factors like CARE, ASA-PS grade, NYHA, DCPB and number of inotropes used influencing morbidity and mortality are consistent with the literature, despite the small size of our sample.

Current management of pancreatic trauma.

BACKGROUND: Although pancreatic trauma is uncommon, it poses a diagnostic and therapeutic challenge. Any delay in diagnosis raises morbidity and mortality. This study highlights the current management and outcome in patients of pancreatic trauma at a single tertiary care center. METHODS: This is a retrospective analysis of prospectively collected data of 24 patients diagnosed to have pancreatic trauma. Collected data was analyzed for age, gender, mechanism of injury, hemodynamic status at presentation, initial serum amylase levels, CECT abdomen findings, AAST-OIS grade of pancreatic injury, injury to other organs, management, complications and outcome. RESULTS: The mean age of these 24 patients was 25 years; 19 were male and 5 females. The mechanisms of pancreatic trauma included blunt abdominal trauma in 21 (87.5%) cases and penetrating injury in 3 (12.5%). Seven (29.16%) patients were managed by non-operative management and 17 (70.83%) underwent surgery. Complications were more frequent in the operative group as compared to the non-operative group. Neither endocrine deficiency nor any mortality was noted in the non-operative management group; while there were 2 cases of endocrine deficiency and 3 mortalities in the operative group. CONCLUSIONS: Pancreatic trauma is more common in young male patients and more commonly inflicted by motor vehicles accidents. Low grade blunt pancreatic injury in hemodynamically stable patients and selected patients with high grade blunt pancreatic injury can be managed successfully by non-operative management with no increase in morbidity or mortality and most patients with high grade blunt pancreatic injury and those having penetrating injuries need surgical intervention.

A randomized study to compare the efficacy of two intravenous fluid regimens of normal saline on the incidence of postoperative nausea and vomiting.

BACKGROUND: The purpose of this study was to evaluate the effect of two different volume of crystalloid given intraoperatively on postoperative nausea and vomiting (PONV). MATERIALS AND METHODS: Eighty adult patients of either sex belonging to ASA I and II class undergoing elective surgeries under general anesthesia for 1-2 h were studied in this prospective, randomized double blinded study. First group (group L) (n=40) received normal saline 4 mL/kg and second group (group H) (n=40) received 10 mL/kg of normal saline. This was in excess of the fasting requirement of the patients. No propofol or antiemetic drugs were given. PONV was evaluated by verbal descriptive score (VDS) [0 = none, 1 = mild, 2 = moderate, 3 = severe, and 4 = unbearable]. Ondansetron (4 mg i.v.) was given if VDS score was 3 or more. RESULTS: The median immediate PONV score was 2 and 1 in group L and H, respectively. The median 2 h PONV score in group L was 3 and in group H was 1. The median 6 h PONV score in group L was 3 and in group H was 1. The 24 h median postoperative PONV score was 1 and 0 in group L and H, respectively. In all these period of time the differences were statistically significant. The incidence of vomiting was more in group L [72.5% (29/40)] than in group H [30% (12/40)]. This was statistically significant (P=0.0003). CONCLUSION: From the current study it was concluded that patients who received larger volume of crystalloid intraoperatively have lesser incidence of PONV.

Anesthetic management in a patient with Kindler's syndrome.

A 35-year-old male with pan-anterior urethral stricture was scheduled to undergo perineal urethrostomy. He was a known case of Kindler's syndrome since infancy. He was having a history of blister formation, extensive poikiloderma and progressive cutaneous atrophy since childhood. He had a tendency of trauma-induced blisters with clear or hemorrhagic contents that healed with scarring. The fingers were sclerodermiform with dystrophic nails and inability to completely clench the fist. Airway examination revealed thyromental distance of 7 cm with limited neck extension, limited mouth opening and mallampatti class III with a fixed large tongue. He was reported as grade IV Cormack and Lehane laryngoscopic on previous anesthesia exposure. We described the anesthetic management of such case on guidelines for epidermolysis bullosa. In the operating room, an 18-G cannula was secured in the right upper limb using Coban(™) Wrap. The T-piece of the cannula was than inserted into the slit and the tape was wrapped around the extremity. The ECG electrodes were placed on the limbs and fixed with Coban(™). Noninvasive blood pressure cuff was applied over the wrap after wrapping the arm with Webril(®) cotton. Oral fiberoptic tracheal intubation was done after lubricating the laryngoscope generously with a water-based lubricant with 7-mm endotracheal tube. Surgery proceeded without any complication. After reversing the residual neuromuscular block, trachea was extubated once the patient became awake. He was kept in the postanesthesia care unit for 2 hours and then shifted to urology ward.

Pre-induction low dose pethidine does not decrease incidence of postoperative shivering in laparoscopic gynecological surgeries.

OBJECTIVES: The incidence of shivering in patients undergoing a laparoscopic procedure is stated to be about 40%. A majority of laparoscopic gynecological procedures are taken up on an outpatient basis. Postoperative shivering may delay hospital discharge and is a common cause of discomfort in patients recovering from anesthesia. AIMS: To determine the effect of pre-induction, low-dose pethidine on postoperative shivering in patients undergoing laparoscopic gynecological surgeries. SETTING AND DESIGN: Sixty females between 25 and 35 years of age, of American Society of Anesthesiologists (ASA) class 1 and 2, were randomly divided into three groups of 20 patients each. Group I and II patients received i.v. pethidine 0.3 mg/kg and 0.5 mg/kg, respectively, while Group III received i.v. 0.9% normal saline just before induction of general anesthesia. Temperature of the Operating Room and the Post Anesthesia Care Unit was standardized and all fluids given during the study period were warmed to 37°C. MATERIALS AND METHODS: Temperature, measured with a tympanic membrane probe, was recorded preoperatively, after induction of anesthesia, on arrival at the Post Anesthesia Care Unit, and postoperatively at 15 minutes and 30 minutes. Shivering was graded (0 - 4 scale) at arrival of the patients to the PACU and every five minutes thereafter, up to 30 minutes. STATISTICAL ANALYSIS: ANOVA, Chi-square test, Kruskal-Wallis ANOVA and Mann-Whitney U tests were used. A P-value of less than 0.05 was considered significant. RESULTS: Core body temperatures were statistically insignificant between groups at pre-induction, post-induction, and in the PACU (P > 0.05). At the end of surgery, shivering was present in 18 patients (30%). In groups I, II, and III, six (30%), three (15%), and nine (45%) patients shivered, respectively. The differences in incidence and grading of shivering among groups was found to be statistically insignificant (P > 0.05). The core body temperature of shiverers and non-shiverers were compared. In the PACU at 0, 15, and 30 minutes, the temperature among shiverers was significantly lower than that in the non-shiverers. Rescue drug i.v. pethidine 20 mg was given to patients with shivering grade ≥2. None of the patients had shivering after 10 minutes. CONCLUSIONS: Prophylactic pre-induction, low-dose pethidine does not have major role in preventing postoperative shivering.

Effect of preoperative oral erythromycin, erythromycin-ranitidine, and ranitidine-metoclopramide on gastric fluid pH and volume.

STUDY OBJECTIVE: To determine whether combining erythromycin with ranitidine is more efficacious than erythromycin or established ranitidine-metoclopramide combination in reducing the volume and acidity of gastric aspirate. DESIGN: Randomized, double-blind study. SETTING: Operating room complex. PATIENTS: Eighty ASA physical status I and II patients. INTERVENTION: Patients were divided into 4 groups of 20 patients each. All patients received the study medication (in tablet form) packed in identical gelatin capsules 60 to 90 minutes before surgery in the premedication room. Patients in group PP were given two placebo tablets; group EP received erythromycin 250 mg, and placebo; group ER received erythromycin 250 mg, and ranitidine 150 mg; and group RM was given ranitidine 150 mg, and metoclopramide 10 mg. MEASUREMENTS: After tracheal intubation, gastric fluid was aspirated via orogastric tube, and volume and pH of the aspirate were studied. RESULTS: Significantly higher gastric volume occurred in group PP than groups EP, ER, or RM (P < 0.001). There were no differences in volumes among groups EP, ER, and RM. Gastric pH was significantly lower (P < 0.001) in groups PP and EP than in groups ER and RM. CONCLUSION: Erythromycin and ranitidine combination is more efficacious than erythromycin alone in reducing the acidity and volume of gastric fluid. No difference was found between erythromycin-ranitidine and ranitidine-metoclopramide combination.

Relevance of day care laparoscopic cholecystectomy in a developing nation.

Feasibility, safety and success of day care laparoscopic cholecystectomy (DCLC) has been well established in advanced countries. The information on (DCLC) is not available from developing nations. All patients of gallstone disease undergoing laparoscopic cholecystectomy under the care of the two participating surgeons at the post graduate Institute of Medical Education & Research were considered for day care laparoscopic cholecystectomy. The selection criteria were: elective cases only, patients less than 70 years, American Society of Anesthesiologists (ASA) grade I and Grade II, living within 20 Kilometers of the hospital, availability of a responsible adult carer at home, access to a telephone and a means of transportation to hospital if needed. Clinical and operative data were recorded prospectively. All patients were discharged 6 to 8 hours after surgery with the advice to contact the surgical team over phone whenever necessary or on the day after discharge. Out of the total 236 laparoscopic cholecystectomy performed over a period of 26 months, 106 patients (44.9%) underwent laparoscopic cholecystectomy as day care procedure. Five patients (4.8%) were admitted after surgery. Four patients were admitted because of conversion and one patient was admitted because of suspected myocardial infarction. Hundred and one patients (95.2%) were discharged on the same day. There was no major morbidity and patient's acceptance was high. Day care laparoscopic cholecystectomy is feasible, safe, and acceptable to patients.
