Saudi Journal of Anaesthesia 2019 13(1):3-8

Background: Physiological and Operative Severity Score for the Enumeration of Mortality and Morbidity (POSSUM) is a validated instrument used to predict morbidity. The aim of our study was to evaluate the performance of the POSSUM score system on predicting perioperative frailty and quality of life (QOL) in elderly surgical patients. Patients and Methods: An observational prospective study was conducted during 3 months. POSSUM was used to determine operative morbidity risk. Patients with a POSSUM score ≥26 were considered as having a high POSSUM (PHP). WHODAS 2.0, EuroQOL-5 dimensions (EQ-5D), Charlson score, and the Clinical Frailty Scale were used to assess the QOL and frailty. Chi-square, Fisher's exact, or Mann–Whitney tests were used for comparisons. Results: Two hundred and thirty-five patients were included. Median age was 69 years; 58% were ASA I/II and 42% ASA III/IV. Frailty was present in 53 patients (23%). Median POSSUM score was 26. Patients PHP were older (median age 71 vs. 68, P = 0.008), more frequently ASA III/IV (P = 0.001), had higher median Charlson scores (7 vs. 5, P = 0.006) and were more frail (49% vs. 26%, P < 0.001). PHP presented more problems in EQ-5D dimensions preoperatively (mobility: 59% vs 41%, P = 0.008; care: 41% vs. 25%, P = 0.013; activity: 52% vs. 32%, P = 0.002; pain: 59% vs. 45%, P = 0.041) but not anxiety (P = 0.137). Three months after surgery, PHP patients presented more problems in mobility: 63% vs. 38%, P < 0.001; care: 48% vs. 31%, P = 0.009; activity: 58% vs. 44%, P = 0.036; pain 59% vs. 37%, P = 0.001 and anxiety: 54% vs. 50%, P = 0.025. Conclusions: Patients PHP were frailer and had worse perioperative QOL.

Background: Whether intraoperative use of hydroxyethyl starch (HES) solutions is associated with postoperative acute kidney injury (AKI) continues to be researched. Urinary neutrophil gelatinase-associated lipocalin (NGAL) is validated for early detection of AKI. Previous studies are limited and use empirically predefined volumes of HES solutions with serum creatinine as marker for AKI. Materials and Methods: Adults scheduled for orthopedic surgery under general anesthesia with >200–300 mL blood loss expected were included; 40 were randomized to receive 6% HES 130/0.4 (tetrastarch) (group HES) or Ringer's lactate (group RL) boluses when stroke volume variation (SVV) >10% in supine or lateral position, or >14% in prone position. Incidence of early postoperative AKI using urinary NGAL (>100 ng/mL) was the primary outcome, and using derangement of serum creatinine was the secondary measure. Results: In 38 patients, intervention was completed, and incidence of AKI (postoperative urinary NGAL >100 ng/mL) among them was 0% in both groups. Patients with urinary NGAL >50 ng/mL were insignificantly higher for group RL versus group HES (6/19 vs. 4/19) (P = 0.461), as were those with incidence of AKI as per creatinine values (5/19 vs. 4/19) (P = 1.000). Group RL had significantly higher requirement of fluid (1211 ± 758 mL vs. 689 ± 394 mL) (P = 0.013) and lower cardiac index (P < 0.05) versus group HES. Conclusion: SVV-guided tetrastarch and Ringer's lactate do not result in postoperative AKI diagnosed by urinary NGAL >100 ng/mL; however, an insignificant trend for better renal functions as well as significantly more efficacious volume expansion and hemodynamic stability were seen with tetrastarch instead.

Background: Hyperhidrosis is a functional disorder identified by excessive sweating. Its incidence is approximately 1% in any population. Bilateral endoscopic thoracic sympathectomy (BETS) intervention is the definitive treatment of choice for palmar and axillary hyperhidrosis. Aims and Objectives: The purpose of this study is to evaluate and compare the quality of life (QOL) and satisfaction rate of patients with upper limb hyperhidrosis before and after BETS surgery and the influence of compensatory hyperhidrosis (CH) on patients' QOL after surgery. Settings and Design: This study is a cross-sectional study designed to generate longitudinal data. Subjects and Methods: This study is a cross-sectional study designed to generate longitudinal data pre- and postbilateral BETS prospectively. This study was conducted in the surgery department of University Hospital in Riyadh, Saudi Arabia. Hundred patients with upper limb hyperhidrosis who underwent BETS from 2014 to 2017 were included. A modified and validated QOL questionnaire for hyperhidrosis was completed by the patients themselves in order to compare the QOL for patients both before and after BETS. Patients' satisfaction and the occurrence of CH were obtained postoperatively. Statistical Analysis Used: Data were analyzed using the SPSS® statistical package for social studies, version 22.0 (SPSS 22; IBM Corp., New York, NY, USA) for Windows®. Results: A total of 100 patients completed the questionnaire; 94% of patients had a positive QOL outcome after the surgery. The mean decrease in QOL scores was −42.0 points toward better QOL. The site of sweating had a significant effect on the patients' QOL before and after the surgery (P value < 0.001). Moreover, 76% of patients reported a high satisfaction rate. Conclusion: Primary hyperhidrosis can negatively impair patients' QOL in different domains. BETS showed to be an effective option for improving the QOL of patients and it provided both short- and long-term effectiveness in treating upper limb hyperhidrosis. CH did not interfere with the rate of patient satisfaction or their QOL postoperatively.

Background: Naso/Orogastric tube (NOGT) misplacement can lead to significant complications. Therefore, the assessment of tube position is essential to ensure patient safety. Although radiography is considered the gold standard for determining NOGT location, new methods may be helpful in reducing repetitive radiation exposure, especially for neonates. In this study, we sought to investigate if bedside ultrasonography (BUSG) can be used to verify NOGT placement in neonatal intensive care patients. Materials and Methods: Infants requiring NOGT placement were enrolled. After insertion of the NOGT, the location was first identified using BUSG and then confirmed using abdominal radiography for comparison. Results: The study cohort included 51 infants with an average gestational age of 34 ± 4.9 weeks. BUSG determined the NOGT location correctly with a sensitivity of 92.2%. The location of the NOGT could not be determined by BUSG in four neonates (7.8%). In one infant, the NOGT was positioned in the esophagus, as determined both by BUSG and radiography. Conclusion: BUSG is a promising diagnostic tool for determining NOGT location in neonates, thereby eliminating the need for abdominal radiography.

Eman Ramadan Salama, Doaa El Amrousy

Saudi Journal of Anaesthesia 2019 13(1):28-34

Background and Objective: Anesthesiologists encounter difficulties during laryngoscopy and tracheal intubation of neonates with myelodysplasia. Tracheal intubation in lateral position in such cases deemed profitable but not easy because of the compromised laryngeal view. We compared GlideScope video laryngoscope (GVL) versus conventional Miller direct laryngoscope (DL) for tracheal intubation in laterally positioned neonates with myelodysplasia. Materials and Methods: Sixty neonates scheduled for elective surgical repair of meningeocele or meningeomyelocele under general anesthesia were allocated randomly for endotracheal intubation using GVL or DL. Percentage of glottis opening (POGO) scores, time to best glottis view (TBGV), endotracheal tube passage time (TPT), intubation time (IT), intubation attempts, and overall success rate of intubation were recorded. Results: TBGV was significantly shorter in GVL group (median = 6.8 s, range = 3.5–28.2 s) in comparison with DL group (median = 8.4 s, range = 4.8–32.7 s) (P = 0.01); however, TPT and IT were comparable. POGO scores were significantly higher with GVL group than DL group (median = 93.8, range = 45–100 and median = 82.4, range 10–100, respectively) (P = 0.001). Overall success of intubation was the same; however, three patients in GVL group required a second attempt for intubation in comparison with five patients in DL group. One patient in DL group required a third attempt. Conclusion: In laterally positioned neonates, GVL is easier than DL with a similar intubation time, comparable time required for tube passage, better views of the glottis, shorter times to obtain the best glottic view, and high success rate as compared with DL. GlideScope seems to be an effective approach for endotracheal intubation of laterally positioned neonates with myelodysplasia.

Chandni Sinha, Neeraj Kumar, Amarjeet Kumar, Ajeet Kumar, Anup Kumar

Saudi Journal of Anaesthesia 2019 13(1):35-39

Background: Infraclavicular approach is a common technique of brachial plexus block. The main difficulty of ultrasound guided technique is in needle visualization due to deep location of the cords. Hebbard et al described a retroclavicular approach wherein the needle was inserted posteriorly to the clavicle. Materials and Methods: In this prospective randomized controlled study, we have compared the classical technique with the retroclavicular approach in terms of needle visibility, block success rate, number of needle passes, block performance time, procedure-related pain, complications, patient and operator comfort and satisfaction. Results: The rate of block success was similar in both the groups. The needle tip and shaft visibility was more in the retroclavicular group (P < 0.05). The number of needle passes was also less in the retroclavicular group. Time for the block procedure was less in retroclavicular group when compared to the classical coracoid group. The patients reported less pain in retroclavicular group (P < 0.05). Discussion: Retroclavicular approach is a feasible option of infraclavicular brachial plexus block in Indian Subpopulation in terms of needle visibility and block success rate.

Saudi Journal of Anaesthesia 2019 13(1):40-45

Aim: We aimed to investigate the changes in respiratory mechanics in adult patients undergoing open heart surgery (OHS) while using volume-controlled auto-flow (VCAF) ventilation mode. Materials and Methods: After obtaining ethics committee's approval and informed consent, 30 patients (17 males and 13 females; mean age: 57.3 ± 17.0 years; mean weight; 74.9 ± 13.6 kg) scheduled for OHS were enrolled. Mechanical ventilation was carried out using VCAF mode (VT: 5–8 mL/kg, I/E: 1/2, 10 ± 2 fr/min). Values of dynamic compliance (Cdyn) and resistance (R) were obtained at six time points (TPs). Normally distributed variables were analyzed with repeated measure of analysis of variance and Bonferroni tests. For abnormally distributed variables, Friedman variance analysis and Wilcoxon signed-rank tests were used. Values were expressed as mean ± standard deviation. P value <0.05 was considered significant. Results: Cdyn (mL/mbar) and R (mbar/L/s) values were as follows – (1) before sternotomy (S): 49.9 ± 17.1 and 7.8 ± 3.6; (2) after S: 56.7 ± 18.3 and 7.1 ± 3.7; (3) after S and after sternal retractor placement: 48.7 ± 16.1 and 8.3 ± 4.4; (4) after weaning from cardiopulmonary bypass and following decannulation while retractor was in place: 49.6 ± 16.5 and 8.1 ± 4.0; (5) after retractor removal: 56.5 ± 19.6 and 7.4 ± 3.7; and (6) after sternal closure: 43.1 ± 14.2 and 9.6 ± 9.1, respectively. Significant differences were observed in Cdynand R between; first and second TPs, second and third TPs, fourth and fifth TPs, and fifth and sixth TPs. Also, significant difference in Cdynwas found between first and sixth TPs, but it was not found in R. Conclusion: Cdyndecreases, but R remains the same in cardiac surgical patients when mechanical ventilation is performed with VCAF ventilation mode. Additionally, Cdynis negatively affected by the presence of sternal retractor and the sternal closure in OHS.

Saudi Journal of Anaesthesia 2019 13(1):46-51

Context: Elderly patients have a higher risk of complications and 30-day mortality than younger patients. Population is aging and this is an emergent preoccupation. Aims: The aim of this study was to evaluate the performance of Physiological and Operative Severity Score for the enumeration of Mortality and Morbidity (POSSUM) system on 30-day mortality in elderly patients submitted to elective surgery. Additionally, the correlation of WHODAS 2.0 and Clinical Frailty Score (CFS) with mortality was evaluated. Settings and Design: An observational prospective study was conducted between May and July 2017. Methods and Material: Patients submitted to elective orthopedic, gynecologic, urologic, vascular, plastic, and general surgery were included. Exclusion criteria were as follows: age <60 years old; inability to give informed consent; emergency/urgency surgery, inability to understand Portuguese; patients admitted in the ICU after surgery. POSSUM was used to estimate postoperative mortality risk. WHODAS 2.0 and CFS were used to assess quality of life and health status. Mortality was evaluated during hospital stay and 30 days after surgery. area under the receiver operating characteristic (AUROC) was analyzed to test the discrimination of P-POSSUM, WHODAS 2.0 and CFS scale. Statistical Analysis Used: Statistical analysis was done using the SPSS Software (version 24.0). Results: POSSUM-predicted mortality was 3.0% with a standardized mortality ratio = 0.87; 95% CI 0.62–0.93; and a good calibration (H–L: P = 0.646); however, the AUROC was poor (0.563). We identified an association between mortality and a higher CFS grade (P = 0.000 and AUROC = 0.859) and a higher WHODAS 2.0 score (P = 0.000 and AUROC = 0.808). Conclusions: WHODAS and CFS appear to be a better assessment tolls for predicting postoperative mortality with a good discrimination comparing with P-POSSUM system.

Nazmy Edward Seif, Ahmed Mohamed ELbadawy

Saudi Journal of Anaesthesia 2019 13(1):52-59

Background: The aim of this randomized controlled study is to compare the safety and efficacy of thoracic spinal versus thoracic epidural anesthesia for open nephrectomy in patients with obstructive/restrictive lung disease. Methods: Sixty patients with mild to moderate chronic obstructive/restrictive lung disease undergoing open nephrectomy were randomized into two groups, 30 patients each. The thoracic spinal group (TSA) group received ultrasound guided mid-thoracic spinal anesthesia, and the thoracic epidural group (TEA) group received thoracic epidural anesthesia. All blocks were performed at the T7-T8. Hemodynamics, visual analogue scale score, sensory and motor block profile as well as any adverse events, and patient satisfaction were all reported. Results: Both blocks were successfully performed and were effective for surgery in all patients, with the exception of only one patient in TSA group who needed to receive general anesthesia even after IV midazolam because of extreme anxiety and was excluded from the study analysis. The sensory block ranges were quiet close, with T2-T5 for the TSA group and T3-T6 for the TEA group as the upper level and L3-L5 as the same lower level. The values for the onset time and the duration of sensory and motor blocks were lower in TSA group. There were no statistically significant differences existed in intraoperative VAS, and hemodynamics between the two groups. Postoperative adverse effects were negligible and insignificant, with no case reporting any neurological sequel. Conclusion: Ultrasound guided thoracic spinal anesthesia can be performed safely and effectively for open nephrectomy in patients with obstructive/restrictive lung disease with the potential for an early ambulation and great patient satisfaction.
