RESUMO
BACKGROUND: Laparoscopic cholecystectomy (LC) is the standard of care for symptomatic gall stone disease. A good scoring system is necessary to standardize the reporting. Our aim was to develop and validate an objective scoring system, the Surgical Cholecystectomy Score (SCS) to grade the difficulty of LC. METHODS: The study was conducted in a single surgical unit at a tertiary care hospital in two phases from January 2017 to April 2021. Retrospective data was analysed and the difficulty of each procedure was graded according to the modified Nassar's scoring system. Significant preoperative and intraoperative data obtained was given a weightage score. In phase II, these scores were validated on a prospective cohort. Each procedure was classified either as easy, moderately difficult or difficult. STATISTICAL ANALYSIS: A univariate analysis was performed on the data followed by a multivariate regression analysis. Bidirectional stepwise selection was done to select the most significant variables. The Beta /Schneeweiss scoring system was used to generate a rounded risk score. RESULTS: Data of 800 patients was retrieved and graded. 10 intraoperative parameters were found to be significant. Each variable was assigned a rounded risk score. The final SCS range for intraoperative parameters was 0-15. The scoring system was validated on a cohort of 249 LC. In the final scoring, cut off SCS of > 8 was found to correlate with difficult procedures. Score of < 2 was equivalent to easy LC. A score between 2 and 8 indicated moderate difficulty. The area under ROC curve was 0.98 and 0.92 for the intraoperative score indicating that the score was an excellent measure of the difficulty level of LCs. CONCLUSION: The scoring system developed in this study has shown an excellent correlation with the difficulty of LC. It needs to be validated in different cohorts and across multiple centers further.

Aim: Acute circulatory failure is commonly encountered in critically ill patients, that requires fluid administration as the first line of treatment. However, only 50% of patients are fluid-responsive. Identification of fluid responders is essential to avoid the harmful effects of overzealous fluid therapy. Electrical cardiometry (EC) is a non-invasive bedside tool and has proven to be as good as transthoracic echocardiography (TTE) to track changes in cardiac output. We aimed to look for an agreement between EC and TTE for tracking changes in cardiac output in adult patients with acute circulatory failure before and after the passive leg-raising maneuver. Materials and methods: Prospective comparative study, conducted at a Tertiary Care Teaching Hospital. Results: We recruited 125 patients with acute circulatory failure and found 42.4% (53 out of 125) to be fluid-responsive. The Bland-Altman plot analysis showed a mean difference of 2.08 L/min between EC and TTE, with a precision of 3.8 L/min. The limits of agreement (defined as bias ± 1.96SD), were -1.7 L/min and 5.8 L/min, respectively. The percentage of error between EC and TTE was 56% with acceptable limits of 30%. Conclusion: The percentage error beyond the acceptable limit suggests the non-interchangeability of the two techniques. More studies with larger sample sizes are required to establish the interchangeability of EC with TTE for tracking changes in cardiac output in critically ill patients with acute circulatory failure.

RESUMO
Parkinson's disease and Schizophrenia fall under low dopamine neurodegenerative and high dopamine psychiatric disorders respectively. Pharmacological interventions to correct mid-brain dopamine concentrations sometimes overshoots the physiological dopamine levels leading to psychosis in Parkinson's disease patients and, extra-pyramidal symptoms in schizophrenia patients. Currently no validated method is available to monitor side effects in such patients, Apolipoprotein E is one of the CSF biomarkers identified in the recent past that shows an inverse relation to mid-brain dopamine concentration. In this study, we have developed s-MARSA for the detection of Apolipoprotein E from ultra-small volume (2 µL) of CSF. s-MARSA exhibits a broad detection range (5 fg mL-1 to 4 µg mL-1) with a better detection limit and could be performed within an hour utilizing only a small volume of CSF sample. The values measured by s-MARSA strongly correlates with the values measured by ELISA. Our method has advantages over ELISA in having a lower detection limit, a broader linear detection range, shorter analysis time, and requiring a low volume of CSF samples. The developed s-MARSA method holds promise for the detection of Apolipoprotein E with clinical utility for monitoring pharmacotherapy of Parkinson's and Schizophrenia patients.

Background and Aims: Ensuring safe central venous catheter tip placement is important. Multiple techniques are available to estimate the length of catheter insertion for subclavian and internal jugular approaches. However, the methods to determine the length of insertion for the axillary route have not been validated. The purpose of this feasibility study was to evaluate a simple method for the calculation of catheter length to be inserted and assess whether it accurately predicts the correct tip placement. Material and Methods: A total of 102 patients requiring preoperative central venous cannulation were evaluated, out of which 60 had successful axillary vein (AxV) cannulation. The length of insertion was calculated using the formula: (2/3* A + B) +Y (A: Clavicular length on chest radiograph [CXR], B: Vertical distance between the sternal head and carina on CXR, Y: Perpendicular distance from the skin to the AxV on ultrasound). A postoperative CXR was used to assess the accurate tip placement (2 cm above the carina to 0.5 cm below it). The primary outcome of the study was the rate of successful placement of the central venous catheter (CVC) in terms of the correct position of the tip of the catheter when the length of the catheter inserted was predicted by the formula described previously. Results: Optimal placement was observed in 83.33% of the cases. A higher rate of accuracy was seen in the females (P value = 0.03) and shorter patients (P value = 0.01). A Bland-Altman plot depicted a high degree of agreement. Conclusion: Use of the formula using a CXR and ultrasound allowed P successful placement of the CVC tip at the desired location in 83.33% of the cases.
RESUMO
BACKGROUND: There are no randomized controlled trials comparing the eTEP with IPOM repair and this randomized study was designed to compare the two techniques in terms of early pain, cost effectiveness, and quality of life. METHOD: This was a prospective randomized trial with intention to treat analysis. The primary outcome was immediate post-operative pain scores. Operative time, conversions, peri operative morbidity, hospital stay, return to daily activities, incremental cost effectiveness ratio and quality of life (WHO-QOL BREF) were secondary outcomes. RESULTS: Sixty patients were randomized equally. Early post-operative pain scores and seroma rates were significantly lower and with a significantly earlier return to activity in eTEP group (p value < 0.05). With negative costs and positive effects, eTEP group was 2.4 times more cost effective. CONCLUSION: eTEP repair is better in terms of lesser early post-operative pain, earlier return to activities and cost effectiveness in small and medium size defects.

Objective: To study the use of serial ultrasound gastric residual volume (GRV) measurements in predicting feed intolerance in critically ill patients. Patients and methods: This study was conducted in various intensive care units (ICUs) of All India Institute of Medical Sciences, New Delhi. Forty-three critically ill patients aged more than 18 years were studied for a total of 130 enteral feeding days. Gastric residual volume was obtained by calculating the antral cross-sectional area (CSA), which is the product of anteroposterior (AP) and craniocaudal (CC) diameters of gastric antrum obtained using ultrasound in the right lateral decubitus position. A baseline measurement was done before the initiation of the enteral feed and termed GRV0, the ultrasound scanning was repeated every 1 hour for the first 4 hours and termed GRV1, GRV2, GRV3, and GRV4, respectively, and the patients were watched for feed intolerance. The receiver operating characteristic (ROC) curves were constructed to correlate the GRV at each time with feed intolerance. Results: The data from 43 medical and surgical critically ill patients were analyzed. Out of 130 feeding days, 13 were noted to be feed intolerant. Gastric residual volume at the end of the fourth hour of feed, that is, GRV4 was the best predictor of feed intolerance with 99.3% area under the curve (AUROC), sensitivity of 99%, specificity of 99.3%, and 95% CI, 0.89-0.98 followed by GRV3, with AUROC of 96% and sensitivity and specificity of 92.3 and 96%, respectively, with 95% CI, 0.92-0.99.

RESUMO
INTRODUCTION: Early graft function is crucial for successful kidney transplantation. Intravascular volume maintenance is paramount in ensuring reperfusion of transplanted kidney. This study was planned to compare whether the timing of fluid infusion can help to decrease amount of fluid given without altering early graft function during renal transplantation. MATERIALS AND METHODS: The present study included forty recipients, randomized into standard (Group-S) or targeted fluid therapy (Group-T). Group S received fluid according to conventional fasting deficit while Group T received at 1 ml/kg/h from the start of surgery till start of vascular anastomosis after which fluid infusion rate in both group was increased to maintain a central venous pressure of 13-15 mm of Hg till reperfusion. Primary outcome measured was serum creatinine level on first postoperative day while secondary outcomes were IV fluid given, perioperative hemodynamics, onset of diuresis, graft turgidity, urine output, and renal function during first 6 postoperative days. RESULTS: The study showed Group T postoperatively had early fall in serum creatinine (day 3) than S (day 6) although this difference was not statistically significant. Group T had received significantly less fluid per kg of dry weight (T-42.7 ± 9.7 ml/kg, S-61.1 ± 11.1 ml/kg, P < 0.001), had early diuresis, better graft turgidity and urine output than Group S. CONCLUSION: Targeted hydration significantly decreases the total amount of fluid infused during the intraoperative period without altering early graft function. Targeted hydration during vascular anastomosis produced stable hemodynamics and early diuresis without any side-effects pertaining to hypo or hyper-volemia.Clinical trial identifier number-CTRI/2016/07/007111.
RESUMO
Background and Aims: Coronavirus disease-2019 (COVID-19) pandemic has affected postgraduate medical education, training, and ongoing research work across specialties. Our survey aimed to analyze the effect of COVID-19 on challenges in pursuing research and academics and ascertain the stressors on residents across medical specialties. Material and Methods: The questionnaire was validated by 10 experts and following ethical approval, this google form-based survey was circulated to postgraduates across specialties across the country through social media platforms over 1 month (22 August 2020 to 21 September 2020). On clicking the link, the participants received brief information regarding the survey followed by the questionnaire. Weekly reminders were sent to the nonresponders till the desired sample size was attained, after which the survey was closed, and responses were analyzed. Results: Four hundred and nineteen of 900 residents completed the survey (46.6% response rate). Majority (88.8%) admitted that the inability to conduct the thesis and break in academics caused a significant amount of mental stress upon them. Though classes had resumed through online platforms for most residents (75.4%), the residents reported that lack of bedside learning (65.4%), inadequate progress tests (26.4%), and delay in thesis topic allotment (84.6% among those not allotted thesis) correlated with increased stress. Fear of extension of the course (53%; P = 0.019) and getting infected with COVID-19 (46.6%; P = 0.019) were most cited reasons for significant stress in most of the residents. Many residents (26%) were unable to sleep properly and 22.1% were unable to concentrate on academics. Majority believed that extension of the submission deadline, reduction in sample size, and change in topic would help to complete thesis. Conclusion: The present survey revealed that there is a major impediment to research and academics of medical postgraduates during COVID-19 pandemic which has markedly increased their stress levels.
RESUMO
BACKGROUND: With evolving technology, the focus of groin hernia repair has shifted to sexual function and fertility outcomes. METHODS: This three-arm randomized study was conducted in tertiary care hospital from 1st July 2017 to 30th March 2019. Consecutive patients of groin hernia were randomized into 3 groups, TAPP (Group 1), TEP (Group 2), and OMH (Group 3). Demographic profile and hernia characteristics were assessed preoperatively. Sexual functions (using BMSFI) and fertility (using surrogate fertility indices, viz., semen analysis and anti-sperm antibodies (ASA)) were assessed preoperatively at 3 months after the surgery. RESULTS: A total of 121 patients were included in the study with 41 patients in TAPP (Group 1) and 40 each in TEP (Group 2) and OMH (Group3) group. All the 3 groups were comparable in terms of demographic profile, hernia characteristics, intra-operative and early post-operative outcomes. Significant improvement was found in most of the domains of BMSFI score in the study population (p value < 0.001) with no intergroup difference. There was significant increase of anti-sperm antibody level in OMH group as compared to TAPP and TEP (p = 0.001), however, the levels were within normal limit. CONCLUSIONS: In conclusion, this study has shown that inguinal hernia repair whether open or laparoscopic (TEP or TAPP) leads on to improvement in sexual functions and fertility indices and can have a significant impact on pre-op counseling of the patient in terms of choice of repair, depending on the available expertise in a given center.

BACKGROUND: Lactate as a target for resuscitation in patients with septic shock has important limitations. The PcvCO2-PaCO2/CaO2-CcvO2 ratio may be used as an alternative for the same. The primary outcome of the study is to evaluate the correlation between serum lactate and PcvCO2-PaCO2/CaO2-CcvO2 ratio measured at various time points to a maximum of 24 hours in patients with septic shock [mean arterial pressure (MAP) <65 mm Hg]. The secondary outcomes were to study the (1) relationship between the PcvCO2-PaCO2/CaO2-CcvO2 ratio and lactate clearance at 6, 12, and 24 hours as compared to the initial serum lactate, (2) to ascertain whether the PcvCO2-PaCO2/CaO2-CcvO2 ratio and the arterial lactate levels in the first 24 hours are able to predict mortality at day 28 of enrollment, and (3) to determine whether the PcvCO2-PaCO2/ CaO2-CcvO2 ratio and arterial lactate are useful in discriminating survivors from nonsurvivors. MATERIALS AND METHODS: Thirty patients with sepsis-induced hypotension who were being actively resuscitated were enrolled. Paired arterial and central venous blood samples were obtained 0.5 hourly till stabilization of MAP and 6 hourly thereafter for the first 24 hours. Patients were followed up to day 28 of enrollment for mortality and organ system failure. RESULTS: A positive correlation was observed between arterial lactate and PcvCO2-PaCO2/CaO2-CcvO2 ratio at 0, 6, 12, and 18 hours (R = 0.413, p = 0.02; R = 0.567, p = 0.001; R = 0.408, p = 0.025; R = 0.521, p = 0.003, respectively). No correlation was seen between PcvCO2-PaCO2/CaO2-CcvO2 ratio and lactate clearance. The subgroup analysis showed that PcvCO2-PaCO2/CaO2-CcvO2 ratio >1.696 at 24 hours of resuscitation predicted 28-day mortality (sensitivity: 80%, specificity 69.2%, area under the receiver operating characteristic curve 0.82). CONCLUSION: The PcvCO2-PaCO2/CaO2-CcvO2 ratio and lactate are positively correlated during the first 24 hours of active resuscitation from sepsis-induced hypotension, and a threshold of 1.696 mm Hg/mL/dL at 24 hours significantly differentiates survivors from nonsurvivors (CTRI/2017/11/010342).

RESUMO
BACKGROUND: Intravenous fluid optimization is an essential component of managing patients in a critical care setting. A cumulative positive fluid balance is consistent with poor outcomes in patients admitted to the intensive care unit (ICU). The overall utility of net cumulative fluid balance as a surrogate for assessing fluid overload has been interrogated. MATERIALS AND METHODS: This study was a prospective single-center observational study, which was done to correlate body weight changes with fluid balance in ICU patients and evaluate its impact on clinical outcomes. Inclusion criteria consisted of adult patients who were admitted to the critical care unit on specialized beds with integrated weighing scales between September 2017 and December 2018. The evaluation of the effect of changes in body weight on ICU survival was the primary objective of the study. RESULTS: We enrolled 105 patients in this study. The ICU mortality was 23.80% with non-survivors showing more weight gain than the survivors. Statistically significant weight gain was documented in the non-survivors on days 3 and 4 (1.9 vs 1.05; p = 0.0084 and 2.6 vs 1.6; p = 0.0030) of ICU admission. Non-survivors had greater cumulative positive fluid balance on fourth, fifth, and sixth days post-ICU admission when compared to survivors (3586 vs 1659 mL, p = 0.0322; 5418 vs 1255 mL, p = 0.0017; and 5430 vs 2305 mL p = 0.0264, respectively). In multivariate regression analysis, cumulative fluid balance did not correlate with days on mechanical ventilation or length of stay in ICU. Changes in body weight and cumulative fluid balance showed a good correlation. CONCLUSION: In patients admitted to the ICU, weight gain on third and fourth days of admission is concordant with increased ICU mortality. Body weight changes were seen to correlate well with the cumulative fluid balance. HOW TO CITE THIS ARTICLE: Mishra RK, Pande A, Ramachandran R, Trikha A, Singh PM, Rewari V.

RESUMO
BACKGROUND AND AIMS: Optimum timing of laryngeal mask airway (LMA) removal after general anesthesia with isoflurane is debatable. The objective was to investigate the potential benefits of removing LMA ProSeal at ≤0.4 Minimum alveolar concentration (MAC) isoflurane over awake and "deep plane" extubation after short duration laparoscopic gynecological surgery. MATERIAL AND METHODS: In this prospective randomized trial 90 adult female patients undergoing elective laparoscopic surgery under general anesthesia using LMA ProSeal™ as airway device were included. At the end of surgery, LMA ProSeal™ was removed when the patient was awake, could open mouth following verbal command (Group A); at MAC ≤0.4 (Group B); or at MAC of 0.6 (Group C). Adverse airway events like nausea, vomiting, airway obstruction, coughing, bucking, laryngospasm were noted. Statistical analyses were done by SPSS statistical software (IBM SPSS Statistics for Mac OS X, Version 21.0. IBM Corp, Armonk, NY). RESULTS: Baseline demographic characteristics were comparable in all three groups. Coughing or bucking at the time of LMA removal was higher in group A (P = 0.004). Snoring and airway obstruction after LMA removal was significantly higher in group C compared to group A and group B (P = 0.002 and P = 0.011, respectively). There was significant change in mean arterial pressure and heart rate between before and after LMA removal on group A (P = 0.008 and P < 0.001, respectively) but not in other groups. CONCLUSION: MAC ≤0.4 can be considered optimum depth of anesthesia for removal of LMA Proseal in adult patients undergoing isoflurane anesthesia.
RESUMO
INTRODUCTION: Minimally invasive approaches are the current standard of care for pheochromocytoma/paraganglioma (PC/PG) surgery. However, a number of patients still undergo open surgery for these tumors. We evaluated the current indications and outcomes of open surgery for PC/PG to define the role of this approach. METHODS: Data of patients undergoing PC/PG surgery between July 2008 and July 2017 were retrieved from our prospectively maintained electronic database and hospital records. Tumor characteristics, operative and recovery parameters, and complications were evaluated for indications of open procedure and outcomes. RESULTS: During the study period, 106 patients underwent 124 procedures for PC/PG, including 18 simultaneous bilateral procedures. Surgeries included 102 adrenalectomies, 18 PG excisions, one partial adrenalectomy, and three partial cystectomies. Twenty-five (23.6%) patients (mean age 38.2 ± 16.1 years) underwent an open procedure, including four bilateral procedures. This included 16 adrenalectomies and 9 PG excisions. The indications for open surgery were unilateral large tumours (5; size 8-16, mean 11 cm), bilateral large tumours (2; size 6-10, mean 8.2 cm), retrocaval tumour extension (4), inter aortocaval PGs (8), Retro-mesenteric PG (1), concomitant procedures (3), and conversion from laparoscopy (2). Mean operative time was 217 ± 63.8 min, blood loss was 868 ± 734.2 ml, 11 patients required blood transfusion, and hospital stay was 6.44 ± 2.4 days. All these parameters were higher than for minimally invasive surgery (MIS) in this cohort. Three patients (12%) suffered a postoperative complication, and the rate of complications was not higher than MIS cohort (16%). CONCLUSIONS: Open surgery was most often indicated for large tumors or those located in the inter-aortocaval region. Most such procedures require large incisions and possible hepatic mobilization on the right side. The procedures can be safely completed with few complications.
RESUMO
INTRODUCTION: Very few randomized controlled trials are available globally to support routine use of enhanced recovery after surgery (ERAS) protocol after radical cystectomy (RC), and none so far has been conducted in the Indian subcontinent. The aim of the present study was to evaluate hospital stay and 30-day perioperative outcomes following RC with the implementation of the ERAS protocol. MATERIALS AND METHODS: Fifty-four patients undergoing open RC were randomized to ERAS versus conventional surgical care (CSC) at our center from April 2017 to May 2018. Key interventions included avoidance of mechanical bowel preparation, early nasogastric tube removal, early enteral feeding, and early obligatory ambulation. Follow-up was done till 30-day postoperatively or till discharge, whichever longer. RESULTS: Twenty-seven patients in each group were analyzed. The demographic profile of the groups was similar. Length of stay in each group (8 days [5-57] ERAS vs. 9 days [5-31] CSC group, P = 0.390) was similar, with time to recovery of bowel function being significantly less in ERAS group (12 h [12-108] vs. 36 h [12-60] for bowel sounds [P = 0.001], 48 h [12-108] vs. 72 h [36-156] for passage of flatus [P = 0.001], and 84 h [36-180] vs. 96 [60-156] for passage of stools [P = 0.013]). Perioperative complication rate (12 patients (44.4%) vs. 14 (51.9%), P = 0.786) was similar. CONCLUSIONS: ERAS protocol leads to faster bowel recovery compared to conventional care in patients undergoing open RC but fails to demonstrate a shorter length of stay and lower complication rate.
RESUMO
INTRODUCTION: Pheochromocytoma surgery is associated with significant hemodynamic and metabolic changes that require post-operative monitoring. We prospectively evaluated the trends of blood pressure, blood sugar, body mass index (BMI), and quality of life (QoL) changes in a cohort of patients undergoing pheochromocytoma surgery to determine the minimum duration of monitoring and assess factors that could predict these changes. MATERIALS AND METHODS: Consecutive patients undergoing surgery for pheochromocytoma over a 20-month period were included in this ethics review board-approved, prospective cohort study. Blood pressure and sugar levels were serially monitored using a fixed protocol in the perioperative period and subsequently at 3 months after surgery. BMI and QoL (using World Health Organization Quality of Life [WHOQOL-BREF] questionnaire) were recorded at baseline and 3 months. Changes were compared and assessed for the predictive factors. RESULTS: Twenty-six patients undergoing 31 procedures were included in the study of whom 8 (30%) developed hypotension and 4 (15%) developed hypoglycemia after surgery. All hypotension episodes occurred within 6 hours of surgery. However, while 3 of the 4 patients who developed hypoglycemia manifest in the first 4 h after surgery, one occurred after 12 h. Occurrence of hypotension correlated with preoperative 24-h urinary vanillylmandelic acid (VMA) levels (P = 0.02) and the total daily dose of prazosin (P = 0.04). Out of 21 hypertensive patients, 7 (33%) had persistent hypertension (HTN) at 3 months and this was associated with age (P = 0.04) and diabetes mellitus (DM) at presentation (P = 0.04). Among six diabetic patients, 1 (16%) had persistent DM. There was significant increase in the BMI (P < 0.0001) and in WHOQOL-BREF scores postoperatively. CONCLUSIONS: Hypotension occurs in 30% patients and hypoglycemia in 15% after pheochromocytoma surgery. Hypotension occurs immediately but hypoglycemia may manifest upto 12h after surgery. Older, diabetic patients are more likely to have persistent HTN. Surgery results in increase in BMI and improvement in QoL.
RESUMO
BACKGROUND: The incidence of shoulder pain (SP) following laparoscopic cholecystectomy (LC) varies between 21 and 80 %. A few randomised controlled trials and meta-analysis have shown lesser SP in LC performed under low-pressure carbon dioxide pneumoperitoneum (LPCP) than under standard-pressure carbon dioxide pneumoperitoneum (SPCP). However, the possible compromise in adequate exposure and effective working space during LPCP has negatively influenced its uniform adoption for LC. MATERIALS AND METHODS: All consecutive patients undergoing elective LC for gallstone disease who met the inclusion and exclusion criteria were enroled. Fourty patients were randomised to SPCP group (pressure of 14 mmHg) and 40 to LPCP group (pressure of 9-10 mmHg). Primary outcome measured was incidence of SP and its severity on visual analogue scale (VAS) at 4, 8, 24 h and 7 days after LC. Secondary outcomes measured were procedural time, technical difficulty, surgeons' satisfaction score on exposure and working space, intra-operative changes in heart rate and blood pressure, abdominal pain and analgesic requirement. Analyses were performed using Stata software. RESULTS: There was no conversion to open surgery, bile duct injury or need to increase intra-abdominal pressure on either group. Twenty-three patients (57.5 %) in SPCP group and nine patients (22.5 %) in LPCP group had SP (p = 0.001). The severity of SP was significantly more in SPCP group at 8 and 24 h (p = 0.009 and 0.005, respectively). Both the groups had similar procedural time, surgeons' satisfaction score, intra-operative changes in heart rate and blood pressure. CONCLUSION: The incidence and severity of SP following LC performed at LPCP are significantly less compared to that in SPCP. The safety, efficacy and surgeons' satisfaction appear to be comparable in both the groups. Hence, a routine practice of low-pressure carbon dioxide pneumoperitoneum may be recommended in selected group of patients undergoing laparoscopic cholecystectomy.

Neuroendocrine tumors which have the potential to secrete catecholamines are either associated with sympathetic adrenal (pheochromocytoma) or nonadrenal (paraganglioma) tissue. Surgical removal of these tumors is always indicated to cure and prevent cardiovascular and other organ system complications associated with catecholamine excess. Some of these tumors have malignant potential as well. The diagnosis, localization and anatomical delineation of these tumors involve measurement of catecholamines and their metabolic end products in plasma and urine, 123I-metaiodobenzylguanidine scintigraphy, computed tomography, and/or magnetic resonance imaging. Before surgical removal of the tumors, the optimization of blood pressure, as well as intravascular volume, is an important measure to avoid and suppress perioperative adverse hemodynamic events. Preoperative preparation includes the use of alpha-adrenergic antagonists, beta-adrenergic antagonists with or without other antihypertensive agents, fluid therapy as well as insulin therapy for hyperglycemia if required. Due attention should be given to type and dose of alpha-receptor antagonists to be used and the duration of this therapy to achieve an optimal level of preoperative "alpha-blockade." Despite this preoperative preparation, many patients will have hypertensive crises intraoperatively which need to be promptly and carefully managed by the anesthesia team which requires intensive and advanced monitoring techniques. The most common complication after tumor removal is hypotension which may require fluid therapy and vasopressor support for a few hours. With advancement in surgical and anesthetic techniques, the incidence of severe morbidity and mortality associated with the surgery is low in high volume centers.
RESUMO
The priority in the management of patients with traumatic hemorrhagic shock is to control the bleeding with simultaneous volume resuscitation to maintain adequate tissue perfusion. Fluid replacement remains the mainstay of initial resuscitation in hemorrhagic shock. Traditionally, vasopressors are contraindicated in the early management of hemorrhagic shock due to their deleterious consequences, although vasopressors may have a role in resuscitation when vasoplegic shock ensues and blood pressure cannot be maintained by fluids alone. Use of vasopressors is not recommended according to the Advanced Trauma Life SupportR management principles. The role of vasopressors remains controversial with no clear guidelines on the timing, type, and dose of these drugs in hemorrhagic shock. Among vasopressors, norepinephrine and vasopressin have been used in the majority of the trials, although not many studies compare the effect of these two on long-term survival in trauma patients. This article reviews the pathophysiology of hemorrhagic shock, adverse effects of fluid resuscitation, and the various experimental and clinical studies on the use of vasopressors in the early phase of resuscitation in hemorrhagic shock.
RESUMO
BACKGROUND AND AIMS: Opioid-free anesthesia decreases postoperative nausea and vomiting, emergence agitation, prolonged sedation, ileus, and urinary retention. The feasibility of the use of dexmedetomidine as sole analgesic agent has been shown in patients undergoing bariatric and gynecological laparoscopic surgery. We explored its use for robotic urological surgery. MATERIAL AND METHODS: Thirty patients were randomized to receive either dexmedetomidine (Group D) or fentanyl (Group F) along with total intravenous anesthesia with propofol. The hemodynamic parameters and number of doses of rescue analgesics used intraoperatively and postoperatively were noted. Recovery parameters at the end of surgery were also recorded. RESULTS: The dose of intraoperative rescue fentanyl was not significantly different between groups (P = 0.13). The hemodynamic profile of patients in the two groups was comparable except the heart rate was significantly more in Group D after intubation and at 60 min. The mean arterial pressure was significantly lower after the initial loading dose of study drug in Group D. The recovery profiles were not significantly different between groups. CONCLUSION: The study reveals that dexmedetomidine has equal analgesic efficacy as fentanyl for intraoperative use and can be used as the sole analgesic agent in patients undergoing robotic urological surgery.
