Brachial plexus block is a common regional anesthesia technique which is performed by anesthesiologists to anesthetize the arm for surgery. In this study, we are investigating the relationship between the nerve conduction (induced by brachial plexus block) and the patients' symptoms before and after the brachial plexus block. We will attach a nerve conduction device (SSEP device) to monitor the patients' arm conduction and we will assess the patients' symptoms simultaneously.
To evaluate the surgical repercussions in patients with traumatic brachial plexus injury in the respiratory and motor systems, trunk biomechanics, functional capacity and quality of life.
Brachial plexus avulsion injury (BPAI) caused by traction injury, especially total root avulsion, represents a severe handicap for the patient. Despite recent progress in diagnosis and microsurgical repair, the prognosis in such cases remains unfavorable. We need to find an relatively optimal surgical treatment.
Intracranial Pressure ( ICP ) monitoring is an essential component of traumatic brain injured ( TBI ) patients management. The clinical signs of raised ICP may be unreliable and may reflect relatively late cerebral decompensation. ICP may be monitored by invasive or non invasive techniques. While invasive techniques show the real time values of ICP, they are associated with many complications like, intracranial bleeding and infection, occlusion of the catheter tip by blood, debris and difficult to locate ventricle in presence of cerebral oedema. All these drawbacks of invasive methods can be averted by employing non invasive techniques of ICP monitoring. Although they do not show a real time value but are excellent tools to detect presence or absence of raised ICP. Elevated ICP can be detected by Computarised tomographic scan (CT) or Magnetic resonance imaging (MRI) but , these techniques are time consuming and require transportation of a patients who may be unstable .The quick and non invasive nature of ultrasonography is fast becoming popular for rapid detection of elevated ICP at bedside in emergency and ICU by monitoring the optic nerve sheath diameter ( ONSD ). Its limitations notwithstanding, ultrasonographic ONSD monitoring is likely to be more reliable than clinical assessment in the diagnosis of intracranial hypertension especially, when patient is under sedation which precludes proper clinical examination. Therefore, in recent years ,among non invasive methods, bedside ocular ultrasonography to monitor ICP has gained popularity. Carbon dioxide being a potent modulator of cerebral vascular tone, alters the ICP by changing the size of cerebral vasculature and thereby, cerebral blood flow (CBF) and this action occurs very rapidly, over e period of few minutes. In a range of PaCO2 20mmHg to 80 mmHg the cerebral blood flow changes in a linear manner. End tidal carbon dioxide concentration(EtCO2) is a surrogate measure of PaCO2 (especially in a haemodyanimically stable patient with healthy lungs ) and is routinely monitored continuously in patients subjected to general anaesthesia. To date there is very little literature on the effects changing EtCO2 on ONSD . This prompted us to conduct this study to find out the effects of different levels of EtCO2 on ONSD.
The purpose of this research study is to demonstrate the safety and efficacy of using two CRS Arrays (microelectrodes) for long-term recording of brain motor cortex activity and microstimulation of brain sensory cortex.
The purpose of this research study is to demonstrate that individuals with upper limb paralysis due to spinal cord injury, brachial plexus injury, amyotrophic lateral sclerosis and brain stem stroke can successfully achieve direct brain control of assistive devices using an electrocorticography (ECoG)-based brain computer interface system.
Brachial plexus injury after shoulder surgery with continuous interscalene block is 2.4% at 1 month and 0% at 6 months, but may be higher with a systematic postoperative neurological examination. Indeed, femoral neuropathy after anterior cruciate ligament reconstruction is 24% at 6 weeks in a cohort of 20 consecutive patients systematically screened with an electromyogram. Brachial plexus injury may be the consequence of the surgery (direct lesion by traction) or the continuous interscalene block. The goal of this study is to define the etiology of this postoperative neuropathy.
Shoulder dystocia is a major obstetric emergency defined as a delivery requiring maneuver in addition to downward traction on the fetal head for delivery of the shoulders. Shoulder dystocia is a major obstetrical complication, occurring in approximately 0.2 to 3% of deliveries, principally due to fetal macrosomia. The obstetrical and neonatal complications associated with shoulder dystocia include newborn mortality occurring in 21 to 290 per 1000 deliveries, generalized asphyxia, fractures, neurological damages (brachial plexus injury) and hematoma. The objective of this study was to evaluate the "pushing" maneuver, that is performed gently on the fetal head since the crowning of the head (appearance of the fetal scalp at the introitus between pushes), aiming to facilitate the anterior shoulder to slip off behind the symphysis pubis, reducing thus the risk of shoulder dystocia. This preventive maneuver may reduce the power (energy/time unit) exerted on the perineal tissues and give the shoulders time to enter the pelvic cavity. The "pushing" maneuver will be evaluated in comparison with either an expectative attitude or a suctioning of fetal nose and mouth.
The purpose of this study is to assess muscle improvement after stem cell injection in the biceps muscle of patients with a brachial plexus injury.
