Validation of a translated version of the modified Japanese Orthopedic Association (mJOA) cervical myelopathy score in an Arabic speaking population.

INTRODUCTION: Degenerative Cervical Myelopathy (DCM) is a growing disorder. Standardization of its assessment tools is an integral part of its management. The modified Japanese orthopedic association (mJOA) score is one of the most commonly used tools. Currently, there is no available Arabic translated version of any cervical myelopathy functional score. This study aimed to translate, culturally adapt, and measure the psychometric properties of an Arabic translated version of the mJOA. METHODS: After translation of the score using the standard forward-backward translation procedure, a validation study including 100 patients was carried out from June 2019 to June 2020. The following psychometric properties were measured: feasibility, reliability, internal consistency, validity, minimal clinically important difference (MCID), ceiling, and floor effect. RESULTS: No problems were encountered during the process of translation and cross-cultural adaptation of the score. The mJOA-AR was found to be a feasible score. It showed high inter-observer reliability (r = 0.833, P < 0.001), test-retest reliability (r = 0.987, P < 0.001) and good internal consistency using Cronbach's alpha (0.777) and Pearson interclass correlation coefficient (r = 0.717). The score showed good convergent and divergent construct validity correlating it to the Arabic validated version of the neck disability index (NDI). The mJOA-AR had an MCID of 1.506. Both the ceiling and floor effects of the total score and the first and second domains were within the acceptable range, while the third and fourth domains had a high ceiling effect (30% and 39%, respectively). DISCUSSION: Our translated version of the mJOA score was found to be a feasible score with acceptable psychometric properties. This score can be utilized as a good outcome measure tool in Arabic-speaking countries.

Comparative Study of Retrobulbar Block versus Ketamine Infusion during Eye Enucleation/Evisceration (Randomized Controlled Trial).

BACKGROUND: The aim of this study is to compare the safety and efficacy of retrobulbar block versus intraoperative ketamine infusion in eye enucleation or evisceration under general anesthesia. MATERIALS AND METHODS: Forty-five patients belonging to American Society of Anesthesiologists Physical Status I and II undergoing eye enucleation or evisceration were randomly allocated to three equal groups (15 patients each). General anesthesia was used as the standardized technique in all patients. Group R received a single retrobulbar injection, Group K received intravenous ketamine infusion, and Group C received normal saline with the same rate of ketamine infusion. Intraoperative heart rate and mean arterial pressure, recovery time, postoperative pain score, time to first rescue analgesic, number of patients who required rescue analgesia, and any adverse events were reported. RESULTS: Postoperative pain Visual Analog Scale was significantly lower in R and K groups in comparison to the C group and was significantly higher in K than R group at 3, 6, 12, and 24 h. In addition, the time to first rescue analgesic was significantly longer in R group (429 ± 54 min) than that in K group (272 ± 34 min), but compared to both groups, it was longer in C group (52 ± 7 min). In K group, the recovery time was longer with higher sedation score in comparison to the other two groups. CONCLUSIONS: Single retrobulbar injection and low-dose ketamine infusion are safe and effective when used as adjuvants to general anesthesia, but retrobulbar block provides better control of postoperative pain with prolonged time to first rescue analgesic and reduced analgesic consumption.

Large Dose Bupivacaine 0.5% versus Small Dose in Elective Cesarean Section.

BACKGROUND AND AIM: The spinal anesthesia in a cesarean section is still presenting a challenge to the anesthetist in the form of either severe hypotension from large bupivacaine dose or insufficient satisfactory anesthesia level conditions as a result of small bupivacaine dose. In this study, we tried to solve this challenge by increasing the dose of bupivacaine to achieve a proper spinal level accompanied by prolonged sitting up to avoid hypotension. PATIENTS AND METHODS: We included 53 patients in this study whom were randomly divided into two groups, namely Group B and Group C. In Group B (25 patients), each patient received 3 mL of bupivacaine and left 5 min sitting up, whereas in Group C (28 patients), each patient received 2.5 mL of bupivacaine and was asked to lie supine immediately. Both groups were tested for hypotension, ephedrine dose, and sensory block level. RESULTS: The present study showed a statistically significant lower dose of ephedrine which was given in Group B (7.2 ± 15.684 mg in Group B versus 27.86 ± 12.04 mg in Group C with P < 0.05). The proper anesthesia level was achieved equally in both groups. CONCLUSIONS: Large dose 15 mg of bupivacaine with the prolonged sitting position will lead to fewer incidences of hypotension and proper anesthesia block.

Using dexamethasone as an adjuvant to levobupivacaine in epidural anesthesia to change the pain intensity and duration in painless labor.

BACKGROUND AND OBJECTIVE: This is a randomized controlled trial aiming at comparing the effectiveness of levobupivacaine alone versus a levobupivacaine with dexamethasone in the epidural injection for painless labor. PATIENTS AND METHODS: This is a comparative randomized controlled double-blinded clinical trial with 49 patients were included in this study, all of them were primigravidas and were during vaginal delivery with a cervical dilatation ≥4 cm. Patients were included randomly in one of two groups either Group C (26 cases) with epidural levobupivacaine 0.125% in normal saline or Group D (23 cases) with epidural levobupivacaine 0.125% in normal saline combined with dexamethasone 8 mg. The duration of a second dose request, total dose given, neonatal outcome and adverse effects of epidural were recorded. RESULTS: Group D showed a longer duration of analgesia than Group C (80.5 ± 12.39 min in Group D vs. 61.75 ± 10.74 min in Group C) with a P < 0.05 (0.001). Furthermore, the patients in Group D received smaller dose of levobupivacaine than those in Group C with a statistically significant difference (90.87 ± 33.42 vs. 127.21 ± 40.68 mg with P = 0.002). There were no statistical differences between the two groups regarding hemodynamics, pain score, neonatal outcome, and complications. CONCLUSION: Dexamethasone in epidural analgesia for painless labor has a prolonged duration of analgesia with no complications for both the mother and the infant.

Open Appendectomy Using Ultrasound Guided Transversus Abdominis Plane Block: A Case Report.

INTRODUCTION: TAB block has been used as an analgesic adjuvant in many abdominal surgeries with fair reliability, but it has never been used as an anesthetic technique. CASE PRESENTATION: In this case report, a 19- year-old male underwent an open appendectomy using ultrasound-guided TAP block as a single anesthetic technique. CONCLUSIONS: It was concluded that under certain circumstances TAP block can be used as an anesthetic modality.

Effect of Single Compared to Repeated Doses of Intravenous S(+) Ketamine on the Release of Pro-inflammatory Cytokines in Patients Undergoing Radical Prostatectomy.

BACKGROUND: Radical prostatectomy is a major surgical procedure that is associated with marked inflammatory response and impairment of the immune system which may affect the postoperative outcome. The aim of this study was to evaluate the effect of preincision single or multiple doses of S(+) ketamine on the pro-inflammatory cytokines, namely tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6). PATIENTS AND METHODS: This is a randomized controlled trial including 60 American Society of Anesthesiologists Physical Status I and II patients scheduled for radical prostatectomy under combined general-epidural anesthesia in Cairo university Teaching Hospital. Patients were randomly divided into three groups each of twenty patients: Group I received no S(+) ketamine (control group), Group II received S(+) ketamine as a single preincision dose, and Group III received preincision and repeated doses of S(+) ketamine. S(+) ketamine was injected as a single intravenous dose of 0.5 mg/kg in Group II and III, repeated as 0.2 mg/kg at 20 min interval until 30 min before the end of surgery. RESULTS: The three groups were comparable in age, weight, and duration of the operation. The study also revealed that a single preincision dose of S(+) ketamine decreased TNF-α to reach 1027.04 ± 50.13 µ/ml and IL-6 to reach 506.89 ± 25.35 pg/ml whereas the repeated doses of S(+) ketamine decreased TNF-α to reach 905.64 ± 35065 µ/ml and IL-6 to reach 412.79 ± 16.5 pg/ml (P < 0.05). CONCLUSION: S(+) ketamine suppresses pro-inflammatory cytokine production, especially when given in repeated doses.

Sonographic Evaluation of Internal Jugular Vein Diameter and Cross-sectional Area Measurements in Correlation with Left Ventricular End Diastolic Area as a Tool for Perioperative Assessment of Volume Status in Pediatric Patients Undergoing Cardiac Surgery.

AIM: The aim of this study is to compare the ultrasound estimation of the cross-sectional area (CSA) and diameter of internal jugular vein (IJV) with left ventricular end diastolic area (LVEDA) for the assessment of intravascular volume in pediatric patients during cardiac surgery. PATIENTS AND METHODS: The CSA and diameter of the left IJV were defined, using ultrasound machine, and compared with LVEDA, estimated by transesophageal echo, in four times intervals (immediately after induction [T1], before the start of cardiopulmonary bypass [CPB] [T2], immediately after weaning of CPB [T3], and at the end of surgery before transfer to the Intensive Care Unit [T4]) as a tool for intravascular volume assessment in 16 pediatric patients undergoing cardiac surgery. RESULTS: There was a poor correlation between IJV CSA and diameter with LVEDA. r values were 0.158, 0.265, 0.449, and 0.201 at the four time intervals (T1, T2, T3, and T4), respectively. CONCLUSION: Estimation of the CSA and diameter of the left IJV using ultrasound is not reliable and cannot be used alone to decide further management.

Comparative study of hyoscine doses as antisialagogue for patients receiving ketofol sedation undergoing colonoscopy procedures.

OBJECTIVE: To compare the effects of different regimens of hyoscine as antisialagogue in patients undergoing ketofol sedation for colonoscopy procedures. PATIENTS AND METHODS: In this prospective double-blind randomized controlled trial 200 American Society of Anesthesiologists I-II aged 20-60-year-old undergoing colonoscopy were randomly assigned into four equal groups, group A received 5 mg hyoscine intravenous, group B received 10 mg, group C received 20 mg intravenous, and control group (D) that was received saline. All patients were sedated using ketofol titrated to achieve Ramsey Sedation Score 4, hemodynamic variables and occurrence of increased secretions were evaluated and recorded. RESULTS: Hyoscine in a dose of 10 mg was the optimum dose to achieve least salivation with the least side effect while hyoscine 5 mg was not efficient to achieve dry field or good surgical conditions. However, hyoscine 20 mg achieved dry field and fair surgical conditions in expenses of tachycardia. CONCLUSION: Hyoscine 10 mg was the least effective dose that significantly reduced hypersalivation in patients receiving ketofol sedation for colonoscopy procedures, this dose was as effective as 20 mg in draying secretion but with significantly less tachycardia.

Difficult airway in a pediatric case of pycodysostosis.

Pycodysostosis is a genetic autosomal rare disease with an incidence of 1:1.7 million births; the pathophysiology of the disease is related to mutation of cathepsin K gene. Sleep apnea, respiratory difficulties because of chest and oral abnormalities may cause a challenge to the anesthetist during intubation and/or mechanical ventilation. In this case report we will discuss a case of pycodysostosis with a difficult airway.
