Perianesthesia Care of the Oncologic Patient Undergoing Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy: A Retrospective Study

PurposeThis study was to understand the perianesthesia care for patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS + HIPEC). MethodThis is a retrospective study. DesignThe perioperative electronic medical records of 189 CRS + HIPEC surgical cases at a hospital of Western Pennsylvania from 2012 to 2018 were analyzed to study the characteristics of perianesthesia care for CRS + HIPEC surgery. FindingsThe patients' median age was 57 (range 21-83) years, and 60% were men. The mean anesthesia time was 10.47 ± 2.54 hours. Most tumors were appendix or colorectal in origin, and the mean peritoneal cancer index score was 16.19 ± 8.76. The mean estimated blood loss was 623 ± 582 mL. The mean total intravenous crystalloid administered was 8,377 ± 4,100 mL. Fifty-two patients received packed red blood cells during surgery. Postoperatively, 100% of the patients were transferred to the intensive care unit. A majority (52%) of patients were extubated in the operating room. Median lengths of hospital and intensive care unit stays were 13 and 2 days, respectively. A majority (73%) of patients had 1 or more postoperative complications and 29% of patients experienced major postoperative complications (Clavien-Dindo grade III or higher) during the hospital stay. Prolonged hospitalization was owing to gastrointestinal dysfunctions and respiratory failure related to atelectasis and pleural effusion. ConclusionsCRS + HIPEC is a major surgery with numerous challenges to the perianesthesia care team regarding hemodynamic adjustment, pain control, and postoperative complications, which demand training and future studies from the perianesthesia care team.

Assessing the Safety of a Novel Neonatal Anesthesia Protocol: A Review of 101 Patients With Early Cleft Lip Repair.

Our study introduces a novel anesthetic protocol for neonates without using volatile agents with the goal to minimize potentially neurotoxic and pro-apoptotic agents. The authors evaluated the short-term safety and efficacy of our anesthetic protocol in patients undergoing early cleft lip repair (ECLR). A retrospective review of ECLR patients who underwent repair before 2.5 months of age within the last 4.3 years was performed. This sample was comprised of 2 groups, those who received either a standard volatile gas-based regimen or a dexmedetomidine-based neonatal anesthetic protocol (DBNAP). Patient demographics, medication dosing, anesthetic time (induction to extubation), major and minor complications, and medication side effects were compared between the 2 cohorts. A total of 101 patients underwent ECLR. All patients were American Society of Anesthesiologists class 1 or 2. Mean age at surgery was 31 ± 13 days and mean anesthetic time was 179 ± 36 minutes. DBNAP was used in 65 patients while the standard anesthetic protocol was used in 36 patients. Patient weight was significantly lower in the DBNAP group (4.01 ± 0.61 versus 4.38 ± 0.72 kg, P = 0.007). There were no significant differences between the 2 cohorts when comparing anesthetic time, emergence time, complication rate, or medication side effects. For patients undergoing ECLR, DBNAP is perioperatively equivalent to the anesthetic standard of care, demonstrating no major complications and acceptable rates of minor complications and medication side effects.

Transvaginal natural orifice transluminal endoscopic versus conventional vaginal hysterectomy with uterosacral ligament suspension for apical compartment prolapse

ObjectiveThe objective of this study was to compare surgical and short-term postoperative outcomes of transvaginal natural orifice transluminal endoscopic surgery (vNOTES) versus conventional vaginal (CV) uterosacral ligament suspension (USLS) surgery. Study designA retrospective cohort study was conducted on 135 patients who underwent hysterectomy with USLS via CV (n = 70) or via vNOTES (n = 65). Patients’ baseline characteristics, surgical characteristics, and surgical outcomes were retrieved. The primary outcome was total operative time. Secondary outcomes include intra- and post-operative complications. ResultsSalpingectomy was performed in all vNOTES procedures and in only 27 % of conventional vaginal procedures (p < 0.005). Compared to the conventional vaginal procedures (n = 65), the vNOTES (n = 70) showed lower mean operative time and mean anesthesia time (101.4 ± 22.3 vs 125.5 ± 27.6 min and 141.4 ± 29.6 vs. 174.0 ± 32.9 min, respectively); and slightly longer median hospital stay (3 [range 2−4] vs. 2 [range 2−4] days, p < 0.05). Compared to women who underwent conventional vaginal hysterectomy with USLS, women who underwent vNOTES hysterectomy with USLS had lower incidences of intraoperative complications (6% vs. 18 %, p < 0.05) and intraoperative ureteral obstruction (0% vs. 8%, p < 0.05); and less estimated blood loss (58 ± 68 ml vs. 143 ± 87 ml, p < 0.05). ConclusionvNOTES hysterectomy with USLS is associated with reduced incidence of intraoperative complications, shorter surgical and anesthesia time, and slightly longer hospital stay, compared to the traditional vaginal surgical approach. Post-operative complications during hospital stay were similar and infrequent following the two procedures.

Analysis of anaesthesia services to calculate national need and supply of anaesthetics in Switzerland during the COVID-19 pandemic.

BackgroundIn Switzerland, details of current anaesthesia practice are unknown. However, they are urgently needed to manage anaesthesia drug supply in times of drug shortages due to the pandemic.MethodsWe surveyed all Swiss anaesthesia institutions in April 2020 to determine their annual anaesthesia activity. Together with a detailed analysis on anaesthetic drug use of a large, representative Swiss anaesthesia index institution, calculations and projections for the annual need of anaesthetics in Switzerland were made. Only those drugs have been analysed that are either being used very frequently or that have been classified critical with regard to their supply by the pharmacy of the index institution or the Swiss Federal Office of Public Health.ResultsThe response rate to our questionnaire was 98%. Out of the present 188 Swiss anaesthesia institutions, 185 responded. In Switzerland, the annual number of anaesthesias was 1’071’054 (12’445 per 100’000 inhabitants) with a mean anaesthesia time of 2.03 hours. Teaching hospitals (n = 54) performed more than half (n = 572’231) and non-teaching hospitals (n = 103) provided almost half of all anaesthesias (n = 412’531). Thereby, private hospitals conducted a total of 290’690 anaesthesias. Finally, office-based anaesthesia institutions with mainly outpatients (n = 31) administered 86’292 anaesthesias. Regarding type of anaesthesia provided, two thirds were general anaesthesias (42% total intravenous, 17% inhalation, 8% combined), 20% regional and 12% monitored anaesthesia care. Projecting for example the annual need for propofol in anaesthesia, Switzerland requires 48’573 L of propofol 1% which corresponds to 5’644 L propofol 1% per 100’000 inhabitants every year.ConclusionsTo actively manage anaesthesia drug supply in the context of the current pandemic, it is mandatory to have a detailed understanding of the number and types of anaesthesias provided. On this basis, the Swiss annual consumption of anaesthetics could be projected and the replenishment organized.

First in Man Pilot Feasibility Study in Extracranial Carotid Robotic-Assisted Endovascular Intervention.

Robotic-assistance in endovascular intervention represents a nascent yet promising innovation. To present the first human experience utilizing robotic-assisted angiography in the extracranial carotid circulation. Between March 2019 and September 2019, patients with extracranial carotid circulation pathology presenting to Houston Methodist Hospital were enrolled. A total of 6 patients met inclusion criteria: 5 underwent diagnostic angiography only with robotic-assisted catheter manipulation, while 1 underwent both diagnostic followed by delayed therapeutic intervention. Mean age was 51 +/- 17.5 yr. Mean anesthesia time was 158.7 +/- 37.9 min, mean fluoroscopic time was 22.0 +/- 7.3 min, and mean radiation dose was 815.0 +/- 517.0 mGy. There were no technical complications and no clinical deficits postprocedure. None of the cases required conversion to manual neurovascular intervention (NVI). Incorporating robotic technology in NVI can enhance procedural technique and diminish occupational hazards. Its application in the coronary and peripheral vascular settings has established safety and efficacy, but in the neurovascular setting, this has yet to be demonstrated. This study presents the first in human feasibility experience of robotic-assisted NVI in the extracranial carotid circulation.

Efficacy, safety, and reliability of surgery on the lumbar spine under general versus spinal anesthesia- an analysis of 64 cases

Quasi-experimental design purposeCompare intra and postoperative parameters, surgeons’ satisfaction, and cost-effectiveness between general anesthesia (GA) and spinal anesthesia (SA) on patients undergoing surgery in the lumbar spine surgery. Overview of literatureSurgery on the lumbar spine is the commonest surgical procedure among all spinal surgical practices. Both the GA and SA are shown to be suitable techniques for performing the surgery safely. GA is used most frequently. But, SA became increasingly more popular because it allows the patient to self-position thereby reducing various complications associated with GA in a prone position. MethodsA total of 64 patients from June 2016 to July 2019 who underwent either discectomy, laminectomy, or lamino-foraminotomy for herniated lumbar disc or canal stenosis in 1 or 2 levels were included. During the study period, 32 patients were non-randomly selected for each of the GA and SA groups. The heart rate (HR), mean arterial pressure (MAP), blood loss, total anesthetic time, surgeons’ satisfaction, analgesic requirements, cost of the procedure, and hospital stay were recorded and compared. ResultsIn the context of demographic characteristics, baseline HR, or MAP, no significant differences were noted between SA and GA groups. Mean anesthetic time, mean PACU time, mean doses of analgesic requirement, cost of anesthesia, and the surgeon’s satisfaction was significantly lower in the SA Group (P < 0.05). The blood loss, duration of operation, and hospital stay were not significant too. No major Intra and postoperative complications were reported nor were significant differences found in either series. ConclusionSafety and efficacy of SA in comparison to GA were similar for the patients undergoing surgery on the lumbar spine. Notable advantages of SA include shorter anesthesia duration, fewer drug requirements, relative cost-effectiveness, and fewer complications rate. Successful surgery can be performed using either anesthesia type.

Endovasküler Aort Onarımında Anestezi Yönetimi

Objective: Our study aimed to examine retrospectively the anesthesia techniques and their results applied to patients who underwent endovascular aortic repair due to aortic pathology. Methods: This retrospective and observational study included patients who underwent EVAR or TEVAR for abdominal and/or thoracic aortic aneurysm between 2015-2021. Patients’ demographic data, type of surgery and anesthesia, duration of surgery and anesthesia, amount of blood transfusion, lengths of stay in ICU and of hospital were recorded. Results: The data of 206 patients who underwent EVAR and TEVAR for abdominal and/or thoracic aortic aneurysm were obtained. TEVAR was applied to 63 patients and EVAR was applied to 143 patients. The procedure was performed under general anesthesia (GA) in all 63 patients who underwent TEVAR, while 15 patients who underwent EVAR were operated under GA and 128 patients under regional anesthesia (RA). The mean anesthesia and surgery times were found 136.1±72.0 min. and 112.2±71.3 min. in GA patients and it was 112.2±71.3 min. and 96.5±32.1 min. in RA patients. The mean length of ICU and hospital stays were determined as 1.6±2.1 days and 3.1±2.7 days in GA patients, and 1.2±0.6 days and 3.1±2.5 days in RA patients. Conclusion: GA or RA methods are preferred as anesthesia techniques in patients undergoing EVAR due to aortic aneurysm. Although RA has advantages compared to GA, such as shorting the lenght of hospital and ICU stays, reducing the blood product requirements, shorting both anesthesia and surgery times, patient characteristics should also be considered in the selection of anesthesia techniques.

Cost unit accounting of strabismus surgery at auniversity eye hospital

HintergrundStrabologische Operationen werden häufig in universitären Zentren durchgeführt. Ziel dieser Arbeit ist es, die Kosten dieser chirurgischen Leistung an einer Universitätsklinik zu ermitteln und die Kostenkompensation für den ambulanten Bereich zu überprüfen.Material und MethodeVon allen Strabismusoperationen an der Medizinischen Hochschule Hannover wurden in den Jahren 2018 und 2019 relevante OP-Daten wie Alter des Patienten, Anzahl der operierten Muskeln, Schnitt-Naht-Zeit, Präsenzzeiten der Chirurgen und Anästhesisten sowie der entsprechenden Funktionsdienste auf Basis des klinikeigenen Informationssystems evaluiert. Im Rahmen einer Kostenträgerrechnung wurden dabei die Kosten für Personal, Material, Raummiete und Overhead kalkuliert.ErgebnisseInsgesamt wurden 302 Operationen (stationärer Anteil: 92,1 %) bis auf wenige Ausnahmen unter Vollnarkose durchgeführt. Das mittlere Alter der Patienten betrug 31 Jahre (Median: 26 Jahre), wobei 33 Patienten Kinder unter 6 Jahren waren. Im Mittel wurden 1,84 Muskeln pro Eingriff operiert. Die mittlere Schnitt-Naht-Zeit betrug 51,5 min, die mittlere Anästhesiezeit 85 min, die Präsenzzeit des Funktionsdienstes OP und auch die des Funktionsdienstes Anästhesie belief sich auf jeweils 104 min, die zusätzliche Aufwachraumzeit auf 66 min. Die am Gesamtprozess durchschnittlich entstandenen Personalkosten summierten sich auf 642,14 € zuzüglich durchschnittlich 109,23 € Material‑/Medikamentenkosten (Operation und Anästhesie) sowie Reinigung und Raumkosten (inklusive Infrastrukturkosten) von 178,71 €. Somit betrugen die Gesamtkosten einer durchschnittlichen strabologischen OP in unserem Kollektiv 930,08 € (Minimum: 491,01 €, Maximum: 1729,29 €). Kostenkalkulationen von Untergruppen ergaben aufgrund unterschiedlicher Behandlungszeiten (37 min für 1 Muskel bis 72 min für 3 und mehr Muskeln) respektive Anästhesiezeiten insbesondere bei Kindern <6 Jahren (durchschnittlich 22 min länger als bei Erwachsenen und Kindern >5 Jahren; Differenz 11 min [1 Muskel], 25 min [2 Muskeln] und 30 min [3 und mehr Muskeln]) deutlich höhere Kosten bei Kindernarkosen und einer höheren Anzahl operierter Muskeln. Das reine Kostenniveau einer Strabismusoperation an unserer Klinik erscheint durchschnittlich um den Faktor 2 höher als das Entgelt, welches für Strabismusoperationen über EBM (einheitlicher Bewertungsmaßstab) im ambulanten Bereich erlöst wird.SchlussfolgerungenDie rein betriebswirtschaftlich errechneten Kosten für strabologische Operationen an einer Universitätsklinik sind signifikant höher als die im ambulanten Bereich nach Paragraf 115b, Absatz 1, SGB V aktuell zu erzielenden Erlöse. Unter diesen Bedingungen können solche Operationen ambulant nicht kostendeckend erbracht werden.

Feasibility and Safety of Robotic Excision of Ipsilateral Retroperitoneal Recurrence After Nephrectomy for Renal Cell Carcinoma

To determine feasibility and safety of robotic excision of local ipsilateral recurrences after nephrectomy for renal cell carcinoma (RCC). Surgical resection is an option for treatment of low burden locally recurrent RCC, potentially delaying the use of systemic therapy. This has historically been performed by open technique, which can impart significant morbidity. We present our experience with robotic excision. We reviewed our institutional experience of patients with surgically excised RCC who underwent robotic excision of ipsilateral retroperitoneal recurrence in 2015-2018. Demographics and clinicopathological variables, including operative and postoperative outcomes, were examined. Twelve robotic excisions of ipsilateral local recurrences were performed in our hospital in 2015-2018. Mean age was 65.48 years (± standard deviation, SD: 9.51), 10 patients were male, and mean BMI 34.75 kg/m2 (± 6.71). Nine patients recurred after radical nephrectomy, and 3 after partial nephrectomy. Mean size of recurrence was 2.97 cm (±1.69). Mean anesthesia time, EBL, and LOS were 213 minutes (± 38.92), 152 mL (± 130.75), and 43 hours (± 12.64), respectively. All surgical margins were negative. No surgical complications were reported. Median follow-up was 19.0 months [interquartile range, IQR 12.7-30.0]. Five patients out of 12 recurred following robotic excision, these were treated with either systemic therapy, radiation, or palliative surgeries. Mean time for subsequent recurrence was 26.5 months. In this small case series, robotic excision of ipsilateral RCC retroperitoneal recurrence appears safe, technically feasible, and oncologically sound in expert hands and carefully selected patients.

Ultrasound-Guided Portal Vein Access and Percutaneous Wire Placement in the Portal Vein Are Associated With Shorter Procedure Times and Lower Radiation Doses During TIPS Placement.

BACKGROUND. TIPS placement is an effective method for treating a number of complications of portal hypertension. Although this complex procedure has been firmly established in treatment algorithms, more data are needed to determine the most efficient and safest ways to perform the procedure. OBJECTIVE. The purpose of this study was to determine the effect of three different techniques of portal vein (PV) cannulation during TIPS placement on procedure efficiency. METHODS. The medical records of patients who underwent TIPS creation between 2005 and 2019 were reviewed. On the basis of the PV access technique used, patients were grouped as follows: group 1 (G1) included patients who underwent a transabdominal ultrasound (US)-guided technique to obtain PV access, group 2 (G2) consisted of those who underwent fluoroscopically guided wedged hepatic portography, and group 3 (G3) included those who underwent percutaneous US-guided PV guidewire placement for fluoroscopic targeting. RESULTS. Of the 264 patients who underwent TIPS creation, 54 (20.5%) were in G1, 172 (65.1%) were in G2, and 38 (14.4%) were in G3. The mean (± SD) fluoroscopic time in G1 (34.8 ± 16.6 minutes) did not differ from that in either G2 (38.9 ± 20.8 minutes; p = .09) or G3 (29.5 ± 14.6 minutes; p = .06). However, G2 patients had significantly longer fluoroscopic times than G3 patients (p = .005). The mean total anesthesia time in G1 (190.2 ± 45.6 minutes) did not differ from that in G2 (199.7 ± 59.5 minutes; p = .15). However, G3 had a mean anesthesia time (162.6 ± 39.7 minutes) that was significantly shorter than that in both G1 (p = .003) and G2 (p < .001). The mean contrast volume was significantly lower in G1 than in G2 (67.9 ± 36.8 mL vs 87.1 ± 42.9 mL; p = .005). More intrahepatic needle passes were required in G2 (median, 4 passes; interquartile range [IQR], 1-7 passes) than in G1 (median, 2 passes; IQR, 1-4 passes; p = .004) and G3 (median, 2 passes; IQR, 1-7.25 passes; p = .04). When complications in G1 and G3 were pooled, this cohort had significantly fewer complications than G2 (p = .01). CONCLUSION. Ultrasound-guided PV access and percutaneous PV guidewire placement for fluoroscopic targeting during TIPS creation are associated with shorter procedure and fluoroscopic times and potentially decreased complications. CLINICAL IMPACT. The present study helps interventional radiologists understand the safest and most efficient way to access the PV, which is a key step during TIPS placement.

3D printing guided surgery in the treatment of unicoronal craniosynostosis orbital dysmorphology.

The purpose of our study was to improve the minor asymmetries of fronto-orbital advancement (FOA) by introducing a simple model to guide the FOA in unicoronal synostosis which may help saving time and cost. A retrospective analysis of 16 consecutive patients with unicoronal synostosis corrected by FOA guided by a guide model. Patients with syndromic craniosynostosis or associated craniofacial anomalies were excluded from the analysis. In all cases, 3D mirror image models were used for guiding unilateral fronto-orbital advancement. Demographic, perioperative, and follow-up data were collected for comparison. Cranial and orbital volumes were documented preoperatively and postoperatively and compared with the non-synostotic side. The postsurgical appearance of the face was documented photographically and then evaluated and scored using the Whitaker scoring system. The study included nine males and seven females. The mean age of the patients at the time of the operation was 20.4 months. The mean follow-up duration was 36 months. Mean operative time was 170 min, mean anesthetic time was 230 min, mean blood loss was 50-80 ml, and the average hospital stay was 4.4 days. No relapse that required surgical correction was reported. There were improvements in the orbital indices and volume to be near equal to the normal side. Excellent to good results were obtained in all patients according to the Whitaker classification system. Residual deformity after FOA mandates another tool to optimize the results. Our study introduced a simple, easy, and applicable method to guide the FOA with lesser asymmetries.

Antegrade Percutaneous Versus Retrograde Ureteroscopic Lithotripsy in Upper Ureteric Cases

Background: The technical advancements in urology have profoundly changed the management of upper ureteric calculus. The present study compared antegrade percutaneous versus retrograde ureteroscopic lithotripsy in upper ureteric cases. Subjects and Methods: The present study was conducted at NRI Medical College &amp; Hospital, Chinakakani, Mangalagiri Mandal, Andhra Pradesh from May 2013 to April 2014 on 60 patients with upper ureteric stones of both genders. Patients were divided into 2 groups. Group I patients were treated with antegrade percutaneous and group II with retrograde ureterolithotripsy. Outcome in both groups was recorded and compared. Results: The mean anesthetic time in group I was 82.4 minutes and in group II was 73.1 minutes, operative time was 45.2 minutes in group I and 58.4 minutes in group II, post- operative stay in group I was 2.6 days and in group II was 1.7 days, stone clearance was seen in 26 patients in group I and 22 in group II. Mean stone size in group I was 1.89 cm and in group II was 1.49 cm. Follow ups days were 71.2 in group I and 83.4 in group II. Clavien-Dindo categorization grade 0 was seen in 16 in group I and 13 in group II, grade 1 in 10 in group I and 12 in group II and grade 2 in 4 in group I and 5 in group II. The difference was significant (P&lt; 0.05). There were 4 and 5 patients in group I and group II with post- operative complications (P&lt; 0.05). Conclusion: Authors found that antegrade percutaneous has better stone clearance rates as compared to retrograde ureterolithotripsy for an upper ureteric calculus.

Are Intoxicated Trauma Patients at an Increased Risk for Intraoperative Anesthetic Complications? A Retrospective Study

Background The purpose of this study was to correlate intraoperative anesthetic complications of trauma patients with their respective urine toxicology results. Methods This retrospective, single-center cohort study at a Level 1 trauma center included patients with the following criteria: (1) trauma admission between January 1, 2010, and December 31, 2016, (2) required surgical intervention, (3) are age 18 and older, and (4) urine toxicology screening was completed. Anesthetic records were evaluated for intraoperative complications. Results The final analysis included 847 patients. The mean anesthesia time, American Society of Anesthesiologists physical status classification scores, change in body temperature, anesthetic complication rate, and mortality were not significantly different between urine toxicology positive and negative patients. Of note, a significantly lower proportion of the urine toxicology positive patients were extubated postoperatively in comparison to urine toxicology negative patients (57.32% vs 63.83%). Conclusions Trauma patients who presented with a positive urine toxicology screening are not at an increased risk for intraoperative anesthetic complications compared to those with a negative urine toxicology screening. However, our results indicated that the need for postoperative mechanical ventilation increased in the acutely intoxicated trauma patients when compared to those without preinjury intoxication.

Simultaneous Bilateral Pediatric and Juvenile Cataract Surgery Under General Anesthesia: Outcomes and Safety

To evaluate the surgical approach, outcome, and safety of bilateral simultaneous cataract surgery (BS-Cat) compared with unilateral cataract surgery (US-Cat) and bilateral 2-timed cataract surgery (BT-Cat) in children. Retrospective, interventional case series. Setting: Department of Ophthalmology, Medical University, Vienna, Austria. Children aged 0-18 years who received cataract extraction owing to a unilateral or bilateral cataract between January 2003 and December 2018 were included. Main Outcomes and Measures: Information regarding the type and duration of surgery and total anesthesia time were recorded. Additionally, intraoperative and postoperative complications including retreatments were evaluated. A total of 220 eyes of 147 patients were included in this analysis (US-Cat: n= 74 patients; BS-Cat: n= 63 patients; BT-Cat: n= 10 patients). The mean age at surgery was 15.94 ± 27.10months in the US-Cat group, 33.47 ± 58.20months in the BS-Cat group, and 41.91 ± 55.09months in the BT-Cat group. The main surgical approach was lensectomy combined with anterior vitrectomy ± IOL implantation (US-Cat: 98.65%; BS-Cat: 95.24%; BT-Cat: 100%; P= .08). Initial intraocular lens implantation was not commonly performed in all groups (US-Cat: 27.03%; BS-Cat: 23.02%; BT-Cat: 50.00%). The mean anesthesia time was shortest in the US-Cat (91.62 ± 26.12min), followed by the BS-Cat (123.81 ± 30.11min) and BT-Cat groups (186.00 ± 42.34min; P < .001), contrary to the duration of surgery (US-Cat: 37.56 ± 15.69min; BS-Cat: 32.33 ± 17.31min; BT-Cat: 37.50 ± 18.67; P= .087). An accidental oxygen decrease below 93% was rare in all groups (US-Cat: 6.76%; BS-Cat: 17.46%; BT-Cat: 10.00%). Intraoperative surgical complications occurred rarely (P= .95) and involved mainly the iris. The number of postoperative complications (P= .17) and interventions (P= .10) was similar in all groups. Visual axis obscuration (US-Cat: 28.38%; BS-Cat: 23.81%; BT-Cat: 20.00%; P= .67) and glaucoma (US-Cat: 6.76%; BS-Cat: 15.87%; BT-Cat: 15.00%; P= .20) showed no difference between the groups. However, nystagmus was more pronounced in the BS-Cat group (US-Cat: 12.16%; BS-Cat: 49.21%; BT-Cat: 20.00%; P < .001), whereas strabismus was more pronounced in the US-Cat group (US-Cat: 68.92%; BS-Cat: 33.33%; BT-Cat: 40.00%; P < .001). Simultaneous removal of bilateral cataract in children showed no statistically significant differences regarding intraoperative and postoperative complications when compared to unilateral and 2-timed bilateral cataract surgery. Anesthesia time was longer in simultaneous bilateral than in unilateral cataract surgery, but only by the surgery time of the second eye. However, prolonged anesthesia time was not accompanied by a decrease of oxygen saturation.

A Prospective Randomized Controlled Trial Using Propofol or Dexmedetomidine for Conscious Sedation in Pediatric Patients Undergoing Sclerotherapy.

ABSTRACTAim:Sodium tetradecyl sulfate (STS) sclerotherapy in pediatric patients is usually undertaken under sedation inside digital subtraction angiography (DSA) suite. These patients are day-care patients and need adequate sedation for small duration. We performed this study to compare propofol and dexmedetomidine as sedative agents in these patients.Materials and Methods:Seventy American Society of Anesthesiologists (ASA) physical status I patients scheduled to undergo sclerotherapy for low-flow venous malformations under sedation were randomized to be administered either dexmedetomidine (Group D) or propofol (Group P). In Group D, initially 2 µg/kg of dexmedetomidine was administered over 10min (or till attainment of a Ramsay sedation score [RSS] of 5), followed by an infusion at the rate of 0.3 µg/kg/h. In Group P, propofol 1mg/kg bolus followed by an infusion at 100 µg/kg/min was administered, titrated to an RSS of 5. We measured intraoperative heart rate, blood pressure, respiratory rate, duration of procedure, and incidence of arterial desaturation, bradycardia, and respiratory depression in the two groups.Results:All the patients in both groups completed the procedure. The mean anesthesia time was significantly longer in Group D. Intraoperative heart rates remained comparable in the two groups, whereas systolic and diastolic BP were significantly higher in Group D throughout the procedure. No patient in Group D experienced arterial desaturation, whereas five patients in Group P reported a SpO2 of <90%.Conclusion:Both propofol and dexmedetomidine can be used for administering sedation in pediatric patients undergoing sclerotherapy for superficial venous malformations in DSA suite. Although propofol provides a rapid onset and reduced duration of action, dexmedetomidine provides reduced episodes of arterial desaturation and respiratory depression.

Cost Analysis of Audiovisual-Assisted Therapeutic Ambiance in Radiation Therapy (AVATAR)-Aided Omission of Anesthesia in Radiation for Pediatric Malignancies

PurposeBecause children cannot reliably remain immobile during radiation therapy (RT) for cancer anatomy targeting requiring millimeter precision, daily anesthesia plays a large role in each RT session. Unfortunately, anesthesia is a source of financial burden for patients’ families and is invasive and traumatic. This study attempts to assess the cost-savings benefit of audiovisual-assisted therapeutic ambiance in radiation therapy (AVATAR)-aided omission of pediatric anesthesia in RT. Methods and MaterialsThe baseline time of anesthesia during RT was derived from documented anesthesia billing time during RT simulation at our institution and from the published literature. Current Procedural Terminology and relative value unit codes encompassing anesthesia-related charges from radiation oncology and anesthesia were analyzed in concert with this value to calculate the total cost of pediatric anesthesia per RT session. ResultsThe mean number of RT fractions administered per patient with AVATAR-directed anesthesia omission at our institution was 19.0, similar to the 17.6 previously reported. At a mean anesthesia time exceeding 30 minutes (with mean RT duration of 4 weeks), the cost of pediatric anesthesia per RT fraction in non-AVATAR sessions was $1,904.35, yielding a total RT treatment anesthesia cost of $38,087.00 per patient (including simulation). Patients at our institution were not billed for AVATAR-assisted RT. ConclusionsThe ability of AVATAR to obviate the need for daily anesthesia in pediatric RT provides substantial cost-savings. These findings argue for increased utilization of AVATAR and for analyses of RT targeting the accuracy of AVATAR versus conventional anesthesia-guided treatment of pediatric malignancies.

Outcomes of Large Bore Vs Small Bore Percutaneous Nephrolithotomy

Objective: To determine postoperative results of large bore vs small bore PCNL. Design and duration: This is a prospective study. It was started in November 2018 and completed in April 2019 after 6 months duration. Setting: Study was conducted in Kidney center of Bahawal Victoria Hospital Bahawalpur. Patients and Methods: Patients having kidney stones and ideal for PCNL were distributed in two groups in randomized way. Group-1 patients underwent small bore PCNL and those in group-2 underwent large bore PCNL. There was equal number of cases in each group. Both male and female patients were included in the study. Mean duration of stay in hospital was 7±3 days. All data collected was analyzed using SPSS and Microsoft office version 2016. Results were calculated in the form of frequencies and percentages and averages. Tables and Graphs used to present data. Consent was taken from ethical committee of the study hospital and consent was also taken from all cases in study group. Results: There were total 90 cases in this study distributed in two groups each containing 45 cases. There were 37 female and 63 male cases. Mean age of patients was 33.5±5 years. Mean anesthesia time was 1.5±0.5 hours in both groups. Mean analgesia given in group-1 was 100±50 mg . Conclusion: In our study small bore PCNL was proved to be better than large bore PCNL associatd with least complications and early recovery with less hospital stay and less use of analgesia.

Comparison of antegrade percutaneous versus retrograde ureteroscopic lithotripsy for upper ureteric calculus for stone clearance, morbidity, and complications

Introduction:The optimal management of upper ureteric calculus remains controversial. We compare the outcomes of antegrade percutaneous ureterolithotripsy (APCUL) with retrograde ureteroscopic lithotripsy (URSL) for upper ureteric calculus with respect to stone clearance, morbidity, and complication rates.Materials and Methods:This prospective study was carried out from December 2014 to June 2016. A total of 117 patients with upper ureteric calculus sized (10–20) mm who underwent APCUL or URSL were included in the study.Results:APCUL and URSL were performed in 64 and 53 patients, respectively. The mean age and stone size were comparable between the two groups. The stone clearance rate at 1-month follow-up was 93.75% in the antegrade group and 81.13% in the retrograde group (P = 0.036). Mean anaesthesia time was significantly longer for the APCUL group while the actual mean operative time was significantly longer for the URSL group (P < 0.001). The overall complication rate was higher in antegrade group (P = 0.804), whereas most of the major complications (Clavien Grade III or more) occurred only in the URSL group (P = 0.007). Blood transfusion was required only in the APCUL group (7.8% versus 0%; P = 0.50). In the URSL group, stone retropulsion occurred in four patients, of which three subsequently required shock wave lithotripsy and one required percutaneous nephrolithotomy in a second sitting.Conclusion:APCUL has better stone-free rates as compared to URSL for an upper ureteric calculus of size 10–20 mm. Although the postoperative minor complications are higher in the antegrade group, severe complications occurred only in the retrograde group. Hence, antegrade approach can be considered as the preferred option to achieve better stone clearance in a single sitting with acceptable morbidity and complication rates.

Nonintubated surgical biopsy of undetermined interstitial lung disease: a multicentre outcome analysis.

Nonintubated surgical biopsy (NISB) of interstitial lung disease (ILD) has shown promise in unicentre reports as a reliable method to achieve pathological diagnosis with low morbidity. The aim of this study was to investigate for the first time early outcomes of NISB of ILD using a multicentre retrospective analysis. Seven European and extra-European institutions participated in the study. Overall, 112 procedures were included. The mean age was 60 ± 12 years (65 men and 47 women). Preoperative total lung capacity and diffusion capacity of carbon monoxide were 74 ± 16% predicted and 57 ± 18% predicted, respectively. Forty-five patients had 1 or more associated comorbidities. NISB of ILD were performed under spontaneous ventilation by intercostal block (n = 84) or epidural anaesthesia (n = 28) with (n = 58) or without (n = 54) sedation and by thoracoscopic surgery (n = 88) or minithoracotomy (n = 24). Mean anaesthesia time, operative time and global time spent in the operating room were 31 ± 31 min, 29 ± 15 min and 89 ± 156 min, respectively. Feasibility was scored as excellent, good, satisfactory or unsatisfactory requiring conversion to general anaesthesia with intubation in 92, 12, 2 and 6 instances, respectively. There were no deaths. Morbidity was 7.1% and included prolonged air leaks in 4 patients and pneumonia, atelectasis, anaemia and gastric bleeding in 1 patient each. A precise pathological diagnosis was achieved in 108 patients (96%). The mean hospital stay was 2.5 ± 2.7 days. Comparisons of results achieved in the largest single-centre series (group A, 60 patients operated on) versus those resulting from the sum of the patients operated on in the other centres (group B, 52 patients operated on) showed no differences in feasibility (P = 0.10) and morbidity (P = 0.10) whereas hospital stay was shorter in group A (1.3 ± 0.5 days vs 3.9 ± 3.4 days, P < 0.001). Results of this multicentre study confirm the satisfactory feasibility of NISB of ILD in 82% of patients with no deaths and a low morbidity rate. Intergroup comparisons indicated that the hospital stay was shorter in group A whereas there were no differences in feasibility and morbidity rates.

Feasibility and safety of irreversible electroporation (IRE) in patients with small renal masses: Results of a prospective study

BackgroundIrreversible electroporation (IRE) has the potential to overcome limitations of thermal ablation, enabling small renal mass (SRM) ablation near vital structures. PurposeTo assess feasibility and safety of percutaneous IRE for the treatment of SRMs. Materials and methodsThis prospective study is a phase 2 trial (NCT02828709) of IRE for patients with SRMs. Primary endpoints are feasibility and safety. Device- and procedural-adverse events were assessed by Clavien-Dindo and Common Terminology Criteria for Adverse Events version 4.0 grading systems. Technical feasibility was assessed by recording the technical success of the procedures. Technical success was evaluated by performing a CT immediately after ablation where complete tumor coverage and nonenhancement were evaluated. Tumor charcateristics and patient characteristics, procedural and anesthesia details, postprocedural events, and perioperative complications were recorded. ResultsTen SRMs were included with a mean tumor size of 2.2 cm (range 1.1–3.9 cm) were treated with IRE. Renal mass biopsies revealed 7 clear cell and 1 papillary renal cell carcinoma. Two renal mass biopsies were nondiagnostic. The median follow-up was 6 months (range 3–12 months). Technical success was achieved in 9 out of 10 cases. One patient had a grade 3 Clavien-Dindo complication (1/10, 95% Confidence interval (CI) 0.0179–0.4041). Mean anesthesia time was 3.7 hours (range 3–5 hours), mean procedural time was 2.1 hours (range 1 hour 45 minutes–2 hours 30 minutes) and mean ablation time was 50 minutes (range 20 minutes–1 hour 45 minutes). The creatinine preoperative and postoperative (1 week, 3 months, 6 months, and 12 months) did not significantly differ. In total, 8 out of 10 cases did not experience postoperative pain. ConclusionIRE in SRMs is safe and feasible. Renal function is not affected by IRE and postoperative pain is rare. Anesthesia time and procedural time are a potential concern.
