Introduction Prehospital management of traumatic pain is commonly based on morphine while locoregional analgesia techniques, especially the femoral nerve block (FNB), can be safely and efficiently used. Adjuvants uses can reduce local anesthetic doses and decrease their related risk. The aim of the study was to assess the analgesic effect of magnesium sulfate when used as an adjuvant in prehospital FNB. Methods This is a randomized double-blinded trial conducted in a prehospital medical department of an academic hospital. Patients with isolated diaphysial femoral fracture and eligible to participate were randomized into 2 groups. Group C had a FNB with 15 ml of lidocaine with epinephrine (300 mg) and 3 ml of normal saline solution. Group I had a FNB with 15 ml of lidocaine with epinephrine (300 mg) and 3 ml of MgS 15% (450 mg). The FNB was performed according to the WINNIE technique. Primary endpoints were morphine consumption and pain intensity during the first 6 hours. Secondary endpoints were the duration of the sensory block, time to the first analgesic request, and side effects occurrence. Results Twenty-four patients were enrolled in each group. Both groups were comparable according to demographic characteristics, initial pain scores, and vital constants. In group I, morphine requirements were significantly lower (2 ± 2 mg versus 5 ± 3 mg, p < 10−3), analgesic onset was significantly faster, and the average time to the first analgesic request was longer (276 ± 139 min versus 160 ± 79 min, p < 10−3). The average duration of sensory block was longer in group I (226 ± 64 min versus 116 ± 70 min p < 10−3). No side effects were recorded. Conclusion Magnesium sulfate should be considered as an efficient and safe adjuvant to lidocaine in prehospital FNB. This trial is registered with (NCT03597945).
We report the observation of a 25-year-old pregnant patient of 39 weeks of amenorrhea proposed for elective cesarean section. This patient suffers from hypertrophic cardiomyopathy since the age of 12. She has an implantable cardioverter defibrillator (ICD). The peculiarities of the ICD in the parturient and the perioperative management of the patient are being reported in this paper.
Malignant hyperthermia (MH) is a rare pharmacogenic disorder of skeletal muscle calcium regulation, resulting from general anesthesia that can be fatal. Most cases are caused by administration of volatile anesthetics or depolarizing muscle relaxants.
It has been generally reported that both of sevoflurane and succinylcholine can induce the delayed onset of MH.
Here, we report a case of malignant hyperthermia in a four-year-old girl during anesthesia induction for unilateral congenital ptosis surgery, two minutes after sevoflurane and succinylcholine administration. The crisis was atypical but early recognized and managed by administration of dantrolene with symptomatic treatment.
Bilateral retinal detachments and cortical blindness are rare complications of preeclampsia and the association of the two pathologies is exceptional. We report the case of a preeclamptic patient who presented with an acute bilateral vision loss. Besides, her ocular ultrasound revealed bilateral retinal detachments and an elevated optic nerve sheath diameter. The patient underwent an urgent cesarean section. Subsequently, magnetic resonance imaging and ocular fundus examination confirmed the diagnosis.
