Background:
Inflow occlusion of the portal triad is a common blood loss-reducing method during hepatectomy which may induce ischemic-reperfusion injury of the remaining parts of the liver. Dexmedetomidine is used for reducing ischemic-reperfusion injury in hepatectomy.
Aim:
The aim of this study was to assess the protective effect of dexmedetomidine on liver after partial hepatectomy using inflow occlusion.
Setting and Design:
This prospective controlled, double-blinded, randomized study included any patients of either sex with age between 20 and 70 years, those in physical status American Society of Anesthesiologists Classes I and II, and those who were planned for partial hepatectomy.
Patients and Methods:
Patients with elective hepatectomy were randomized into dexmedetomidine group, which received dexmedetomidine at 0.3 mg/kg/h, and control group, which received a placebo.
Statistical Analysis:
Statistical analysis was performed using IBM SPSS software version 18. Data were tested using Kolmogorov–Smirnov test, independent
t
-test or Mann–Whitney U-test, and Chi-square or Fisher's exact test. The statistical significance was considered at
P
< 0.05.
Results:
Serum albumin, aspartate aminotransferase, alanine aminotransferase, prothrombin time were higher in control group in comparison to dexmedetomidine group. Hypotension duration was lower in control group in comparison to dexmedetomidine group. Vasoconstrictor usage, amount of blood loss, and colloid, crystalloid, and blood given to patients were higher in control group in comparison to the study group.
Conclusions:
Dexmedetomidine can protect the liver during hepatic resection surgery with inflow occlusion with decreasing blood loss and need for blood transfusion.
Background: Postoperative pain management in children can be effectively controlled using regional analgesic techniques. In general, neuraxial blocks pose a higher risk of adverse effects and complications in comparison to peripheral nerve blocks. Recently, both quadratus lumborum block (QLB) and erector spinae plan block (ESPB) have been used to achieve adequate postoperative analgesia in children. We compared the efficacy of both in postoperative pain management after laparoscopic abdominal surgery.
Methodology: Eight five patients with laparoscopic abdominal surgery received either bilateral QLB or ESPB at the level of T8 transverse process with 0.5 ml/kg of 0.25% bupivacaine to achieve adequate postoperative analgesia. FLACC score was used to assess pain score after surgery and the need for rescue opioid analgesia.
Results: The average dose of fentanyl was lower and the time to the first dose of rescue analgesic was longer in QLB group when compared to ESPB group. In addition, FLACC scores were significantly lower in QLB group in comparison to ESPB group at the 6th, 8th, 12th and 20th h after surgery.
Conclusion: Quadratus lumborum block can provide longer and more effective postoperative analgesia in pediatric patients following laparoscopic abdominal surgery in comparison to erector spinae plan block.

Background:Lumbar puncture is a difficult medical skill and is used for administering subarachnoid anesthetic medications. Estimation of skin to subarachnoid space depth (SSD) helps to reduce post spinal anesthetic complications.Aims:To measure the SDD in overall Egyptian population and to find a formula for predicting SSD in Egyptian patients.Settings and Design:Four hundred patients of American Society of Anesthesiologist class I and II adult Egyptian patients undergoing surgery using spinal anesthesia in general and obstetric surgery unit, Mansoura University main hospital, were included in this prospective, observational study.Subjects and Methods:Patients were divided into three groups: Males (Group M), nonpregnant females (Group F), and pregnant females (Group PF). SSD was measured after performing lumbar puncture. The relationship between SSD and patient characteristics was studied; correlated and statistical analysis was used to find a formula for predicting SSD.Statistical Analysis Used:Statistical analysis was done using Statistical Package for Social Sciences (SPSS 19.0, Chicago, IL, USA). One-way ANOVA with post hoc (Bonferroni correction factor) analysis was applied to compare the three groups. All the covariates in the study further were taken for multivariate analysis. Multivariate regression analysis was performed to evaluate important covariates influencing SSD for each group separately.Results:Mean SSD was 4.99 ± 0.48 cm in the overall population. SSD in adult males (4.93 ± 0.47 cm) was significantly longer than that observed in females (4.22 ± 0.49 cm) but was comparable with SSD in parturient (4.32 ± 0.47 cm). Formula for predicting SSD in the overall population was 2.1+ (0.009 × height) + (0.03 × weight) + (0.02 × body mass index [BMI]) + (0.15 × body surface area [BSA]). Craig's formula when applied correlated best with the observed SSD.Conclusions:SSD in adult males was significantly longer than that in both pregnant and nonpregnant females, but it was nearly the same in pregnant and nonpregnant females. SSD in Egyptian population can be calculated based on height, weight, BMI, and BSA. Craig's formula was the most suitable to be applied to Egyptian population.
Background: Foreign body aspiration in pediatrics is usually managed by rigid bronchoscopy, which is associated with plenty of adverse events. Objective: We tried to compare the effect of nebulized saline, lidocaine or combined lidocaine with epinephrine on postoperative respiratory complications. Patients and methods: This prospective study included 90 children, who were divided into three groups according to the nebulized solution; NS group (normal saline 0.9%), L group (lidocaine 1% 4 mg.kg -1 ) and LA group [4 mg.kg -1 lidocaine 1% and adrenaline (1:1000) 3 mg). Our primary outcome was the incidence of post-operative respiratory complications, while the secondary ones included hemodynamic changes and the incidence of intraoperative cough or desaturation. Results: All pre-procedural data were insignificant among the three groups. The LA group expressed higher heart rates, while the L group showed a significant reduction when compared to NS group. Propofol consumption showed a significant decline in two studied groups compared to the NS group. Intraoperative cough was higher in NS group in comparison to L and LA groups. Although, intraoperative desaturation per case along with post-operative sedation showed no significant difference among the three groups, post-operative cough frequency attacks and severity were higher in NS group when compared to L and LA group and when L group were compared to LA group. Postoperative stridor was insignificant among the three groups. Conclusion: Nebulized lidocaine/adrenaline combination is appropriate option to achieve proper intraoperative sedation and upper airway conditions with reduction of post-operative negative respiratory outcomes together with minor hemodynamic changes.
