Aim The aim of this prospective randomized study was to compare the effect of enteral nutrition (EN) and intradialytic parenteral nutrition (IDPN) on malnourished hemodialysis patients receiving nutritional support admitted in the intensive care unit. Patients and methods A total of 135 patients between 18 and 60 years of age admitted in Ain shams University Hospitals’ intensive care units and on regular hemodialysis were randomly allocated to three groups of 45 each. Group A received enteral and IDPN (250 ml dextrose 25%, 250 ml intralipid 10%, 250 nephrosteril 7%, and trace elements and vitamins). Group B received enteral and IDPN (250 ml dextrose 25%, 250 ml intralipid 10%, 250 aminosteril N-Hepa 8%, and trace elements and vitamins). Group C received only EN. The following evaluations were carried out: biochemical evaluation, which included serum albumin, prealbumin, transferrin, and urinary urea nitrogen evaluation every 20, 4, 8, and 0 days, respectively, and after 6 weeks at the end of the study, and anthropometric parameter measurement, which included BMI, mid-arm circumference, and dialysis malnutrition score (DMS). Results Serum albumin, prealbumin, BMI, and DMS significantly increased (P≤0.001) at the end in all groups. Serum transferrin increased only in groups A and B (P≤0.001), and there was a nonsignificant increase in group C (P≤0.05). No significant difference was found at the end between group A and group B as regards serum albumin (P=0.056), serum prealbumin (0.062), serum transferrin (0.0942), BMI (0.455), and DMS (P=0.840). Serum albumin, prealbumin, transferrin, and BMI showed a significant difference (P≤0.001) in group C at the end of the study in comparison with groups A and B with lower SD. Conclusion IDPN, either aromatic or branched amino acid, in addition to EN showed the same and greater improvement compared with patients who received only EN.","PeriodicalId":7492,"journal":{"name":"Ain-Shams Journal of Anaesthesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84986242","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Patients and methods this study, group D (n=30) received DEX diluted to 4 μg/ml and infused at a rate of 0.1–0.2 μg/kg/h, whereas group C (n=30) received an equal volume of saline at an infusion rate of 0.1–0.2 μg/kg/h immediately from the end of surgery and postoperatively in the ICU thereafter. Postoperative analgesia was assessed using the Numeric Pain Intensity Scale, and sedation was assessed using the Modified Ramsay Score at T1, T2, T3, T4, T5, and T6 for the first 24 h, as well as postoperative rescue morphine analgesic requirements. Statistical analysis Analysis of data was performed using the Student t-test for independent samples for parametric data and using the χ2-tests for categorical data. Results There was a significant decrease in the pain scores in group D compared with group C (P<0.001). Morphine rescue analgesia was needed in 10% of patients in group D and in 95% of patients in group C, with a significant reduction in time to extubation and ICU length of stay in group D.

As the ProSeal laryngeal mask airway (PLMA) is considered the ‘state-of-the-art’ supraglottic device, we conducted this randomized trial to evaluate the safety and efficacy of air-Q SP compared with that of PLMA in pediatric patients. Patients and methods The study included 70 pediatric patients aged from 4 to 15 years undergoing elective surgery under general anesthesia who were randomized to either the air-Q SP group or the PLMA group. The primary outcome parameter in this study was the oropharyngeal leak pressure, and the secondary outcome parameters were ease of insertion, time of insertion, first attempt insertion success rate, number of gastric insufflations, fiberoptic glottic view, and complications related to the supraglottic airway device use. Results There was no significant difference between air-Q SP and PLMA regarding first insertion success rate, ease of insertion, oropharyngeal leak pressure, number of gastric insufflations, number of manipulations required to adjust the airway, and complications. Time to insert the air-Q SP was significantly shorter than that of PLMA (13.2±4.2 vs. 17.5±4.8 s, P=0.03). The fiberoptic view was significantly better with air-Q SP than with PLMA (P=0.018).

C-MAC videolaryngoscope (VL) is a relatively recent development that improves the success of tracheal intubation. Aim The aim of this study was to compare and evaluate the effects of dexmedetomidine for attenuation of hemodynamic responses during laryngoscopy using Macintosh laryngoscope versus C-MAC laryngoscope. Patients and methods A total of 60 patients, ASA II, 18–60 years old, scheduled for different surgeries under general anesthesia with BMI up to 40 kg/m2 were included in the study. Patients were divided into two groups (30 patients each) and were appropriately positioned, and intubation was done. Hemodynamic stress response to intubation was recorded, and plasma epinephrine level was estimated at baseline and at 1 and 5 min after intubation. Success rate, duration, attempts of intubation, and SpO2% were assessed. Results Plasma epinephrine level (ng/ml) at baseline and at 1 and 5 min after intubation showed no statistically significant difference in both groups, but there were highly significant differences at 1 and 5 min after intubation compared with baseline values (P<0.0001 and <0.0007, respectively) in each group. Intubation time was longer in ML (17±4.47 s) compared within VL (12±3.4 s). There were no significant differences between both groups after intubation regarding hemodynamic changes, SpO2, or EtCO2. Conclusion The stress response in both laryngoscopic techniques appears to be the same as detected by the nonsignificant difference in plasma epinephrine levels and hemodynamic changes in both groups, so 1 μg/kg dexmedetomidine is not enough to obtund the stress response completely. C-MAC VL is an efficient and suitable intubating device and provides excellent visualization of laryngeal structures in shorter time with less intubation attempts than Macintosh (Techron Surgical, Sialkot, P, Pakistan) laryngoscopy.","PeriodicalId":7492,"journal":{"name":"Ain-Shams Journal of Anaesthesiology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79093408","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Controlled hypotension is one of these measures used to limit intraoperative blood loss to provide the best possible surgical field. The aim of this study was to compare the effect of a fixed dose of dexmedetomidine (DEX) and nitroglycerin (NTG) with NTG alone on hemodynamic parameters, NTG dose, surgeon satisfaction, and blood loss during controlled hypotensive anesthesia in FESS. Patients and methods Fifty patients of both sexes, classified as American Society of Anesthesia physical status I and II, aged between 20 and 50 years, and candidates for FESS were randomly allocated into two groups by using the sealed envelope method. Group I (n=25) received hypotensive anesthesia with NTG and group II (n=25) received hypotensive anesthesia with NTG and DEX. DEX 1 μg/kg over 10 min was given, and then infused by a syringe pump at a fixed rate of 0.5 μg/kg/h before induction of anesthesia in group II only. After induction and intubation NTG was infused in both groups and titrated to obtain a target mean arterial blood pressure (MAP) of 55–65 mmHg. The MAP and heart rate (HR) were measured at baseline, and then periodically. The following parameters were also recorded: duration of surgical interference (time from the beginning to the end of surgical intervention), blood loss volume, surgeon satisfaction, time to achievement of the target MAP, time to reversibility of MAP to baseline, and the highest dose of NTG needed to reach target MAP. Results There was no significant difference between two groups regarding demographic data, basal hemodynamics, duration of surgical intervention, American Society of Anesthesia physical status, surgeon satisfaction, and all measurements of MAP except time of intubation, which was significantly less in group II. On the other hand, there was a significant difference between both groups regarding HR, time to achievement and reversibility of MAP, blood loss volume, and the highest dose of NTG needed to reach the target MAP, as all of these measurements were significantly lower in group II.

Most surgeries, including cataract surgeries, can be safely performed in an outpatient setting using local anesthesia. Levobupivacaine, a levorotatory isomer of the racemic mixture of bupivacaine, has been used at regional blocks, including local eye blockades. Dexmedetomidine, a potent, highly selective and specific α2-adrenoreceptor agonist, with both sedative and analgesic effects and no respiratory depression, is used as an adjuvant to local eye anesthesia to prolong the analgesic duration of the local anesthetic used. We expected that the addition of dexmedetomidine to levobupivacaine would increase both sensory and motor block durations compared with levobupivacaine alone. Patients and methods In our study, a total of 80 patients of both sexes, aged 50–70 years, belonging to the American Society of Anesthesiologists (ASA) grade I and II, and scheduled for phacoemulsification cataract surgery were randomly allocated into one of two study groups: the levobupivacaine group (group L), in which 40 patients received 3 ml of 2% lidocaine with 10 IU/ml of hyaluronidase + 3 ml of 0.5% levobupivacaine+1 ml of normal saline; and the levobupivacaine dexmedetomidine group (group LD), in which 40 patients received 3 ml of 2% lidocaine with 10 IU/ml of hyaluronidase+3 ml of 0.5% levobupivacaine+1 ml of dexmedetomidine (100 μg). Results There was no significant difference between the two groups regarding the onset times of lid akinesia, globe anesthesia, and globe akinesia (P > 0.05). The duration of globe anesthesia, lid akinesia, and globe akinesia in the dexmedetomidine group was significantly longer than in the levobupivacaine group (P < 0.001).
