Background Brachial plexus is a network of nerves that arises from the neck passing through the axilla to supply the whole upper limb with motor and sensory supply. Our target in upper limb surgeries is to block this plexus using local anesthetics. Different adjuvants have been mixed with local anesthetics (LAs) for peripheral nerve blocks (PNBs). These drugs usually affect may delay the onset of action and prolong the duration of analgesia. Objective The aim of the present study was to compare the effect of Magnesium with bupivacine vesus bupivacine alone in supraclavicular nerve block ultrasound guided in upper limb surgeries Patients and Methods In our study 82 patients are randomly divide into two equal groups, control group received only bupivacine 0.5 % and magnesium group received 250 mg in addition to bupivacine 0.5% Results Our study showed that addition of 150 mg of magnesium to bupivacine in ultra sound guided supraclavicular block prolong the onset time of both sensory and motor block (p value >0.05) non significant. But it significantly prolonged their duration, p value <0.05 for sensory block and <0.001 for motor block which was highly significant Conclusion Addition of magnesium also did not affect the hemodynamics as regard systolic, diastolic blood pressure and o2 saturation. The previous findings proved that adding magnesium to bupivacine is more superior than the use of bupivacine alone.

Objectives Post dural puncture headache (PDPH), since it is first described by August Bier in 1898, remains a common complication in spinal anesthesia (SA). Many pharmacological agents are suggested for PDPH management as acetaminophen, caffeine, non-steroidal antiinflammatory drugs, corticosteroids, and sumatriptan. Aim The aim of this study is to compare between the prophylactic effect of each of; aminophylline, gabapentin, and neostigmine added to atropine on the occurrence of PDPH after caesarean section (CS) under SA. Subjects and Methods This prospective randomized controlled clinical study was carried out 75 pregnant female patients 20-40 y, 60-100 kg. ASA physical status II undergoing elective CS. Patients were randomly divided into 3 groups (25 patients in each); group A: received 250 mg aminophylline IV immediately after delivery of the infant, group B: received IV neostigmine 20 µg/kg added to atropine 10 µg/kg immediately after delivery of the infant and group C: received 3 capsules gabapentin 300 mg; the 1st before SA by 2 h with sip of water, the 2nd after CS by 6 h and the 3rd after 14 h from CS. Results The incidence of PDPH was lower in group A (8% vs 40% in group B and 24% in group C. The onset of PDPH was significantly delayed in group C than group A and in group C than B, but insignificant between group A and B. The duration of PDPH and total dose of analgesic requirement was significantly lower in group A than group B and C and in group B than C. Heart rate (HR) showed significant increase in group A (post aminophylline than pre) only. HR in the other groups and mean arterial blood pressure showed insignificant difference among the three groups (between pre and post administration of drugs). As regards VAS, there was no significant difference in the three groups at 3 h. There was significant difference among the three groups at 6, 12, 24, 36, 48 and 72 h. (between group A & B from 24h up to 72h, between group A & C from 6 up to 72h and between group B & C at 6 h only (delayed onset with neostigmine)). Side effects were minimal and tolerable. Conclusion Aminophylline reduced the incidence and duration of PDPH after CS under SA more than gabapentin and neostigmine with less analgesic requirement and minimal side effects. Also, neostigmine was superior than gabapentin in delaying the onset and decreasing the duration of PDPH.

Background and aim Intraoperative use of a single bolus dose of tranexamic acid may not be sufficient to prevent bleeding in the early postoperative period. The present study was carried out to compare the effect of two dose regimens of tranexamic acid in reducing perioperative blood loss and the amount of allogeneic blood transfusion in transurethral resection of prostate. Design prospective, double-blinded and controlled study. Setting Ain Shams University Hospital, Patients and Methods 50 patients electively posted for transurethral resection of prostate were randomly assigned to receive a single bolus dose of tranexamic acid (10 mg/kg) (Group A), a bolus dose of tranexamic acid (10 mg/kg) followed by infusion (1 mg/kg/h) till 4 h postoperatively (Group B). Measurements Total intraoperative blood loss, amount of allogeneic blood transfusion, postoperative drain collections, and hemoglobin and hematocrit levels were recorded at different time intervals. Data obtained after comparing two groups were analyzed using the statistical package for social sciences. Results There was no statistically significant difference among patients in both groups regarding intraoperative blood loss and postoperative blood loss at 6 hrs and 48 hrs postoperatively. However the post-operative blood loss at 24 hrs was significantly higher among patients in group A than patients in group B (P-value= 0.014) . Conclusion Tranexamic acid causes more effective reduction in post-operative blood loss when used as a bolus followed by an infusion continued in the postoperative period in comparison to its use as a single intravenous bolus in transurethral resection of prostate.

Background Various adjuvants have been used to prolong spinal anesthesia, with the additional advantages of delaying the onset of postoperative pain and reducing postoperative analgesic requirements. Pregabalin is an R-aminobutyric acid analog that binds to the α2-δ subunit of presynaptic voltage-gated calcium channels. Objective The aim of this work is to evaluate the efficacy of a single dose of pregabalin in terms of spinal blockade duration and its potential opioid-sparing effect during the first 24 hours postoperatively Patients and Methods There were limitations to the present study. First, since only 1 dosage of pregabalin was evaluated, we could not determine the most effective dosage. Second, clinically meaningful improvements in recovery were not assessed. Adequate postoperative pain control provides early postsurgical mobilization, shortened hospitalization, and increased patient satisfaction. Third, preoperative pain and anxiety scores were not recorded. Pregabalin might affect the preoperative pain, mood, and anxiety scores, and these factors can be related to the postoperative pain score. Results The mechanisms by which pregabalin premedication prolongs motor and sensory blocks using local anesthetics in spinal anesthesia are not fully understood. There may be several reasons for the prolongation of spinal anesthesia. Gabapentinoids are an r-aminobutyric acid analog that binds to α2-δ subunit of presynaptic voltage-gated calcium channels, and this inhibition decreases postsynaptic excitability by reducing potassium-evoked excitatory transmitter release. These medications provide antiepileptic, anxiolytic, and analgesic features by modulating both GABAergic neurotransmission and calcium influx. Gabapentinoid compounds produce a significant and clinically important improvement in preoperative anxiety scores. Since patients may be anxious in the perioperative period, the anxiolytic effects and euphorigenic effects of pregabalin may be beneficial.
