Abstract Introduction: The ulnar nerve is one of the two terminal branches of the medial cord. It passes down the medial aspect of the arm and runs posterior to medial epicondyle to enter the forearm without branching. Previously, ulnar nerve variations have been consistently located in origin or course of the distal branches. Case Report: In this present case, an unreported rare bifurcation of ulnar nerve was seen in the left lower arm of a 65 year male cadaver with the resulting posteromedial and anterolateral branches arising above the medial epicondyle in.Its phylogeny and implications are discussed in detail. Conclusion: A lack of awareness of variations might complicate surgical repair and may cause ineffective nerve blockade.

Eventration of diaphragm is an uncommon disorder in which diaphragmatic muscle is replaced by fibroelastic tissue, either partially or completely. Bilateral eventration is even rarer. We present a case of bilateral eventration of diaphragm in newborn with a fibroelastic sac on left side and diaphragmatic eventration with good muscular lips on right side. The right-sided diaphragmatic eventration was not evident initially, but manifested after surgical repair of the left-sided eventration.

Intrapericardial procaine has been used by several groups to block cardiac afferent nerves to study effects of cardiogenic reflexes. In eight conscious rabbits, procaine (17–113 mg ipc; median 32) blocked cardiac efferents. Procaine (17–113 mg ipc; median 39) abolished the reflex depressor effects of the cardiac C-fiber excitant 1-phenylbiguanide (PBG), and in four of eight rabbits prevented the hypotensive phase 2 of acute central hypovolemia, which has been attributed to a signal from the heart. However, in three of the rabbits respiratory incoordination and blood gas abnormalities developed. In another study of four rabbits, procaine (165–335 mg ipc; median 235) invariably caused phrenic nerve blockade and underventilation. In three rabbits, after intrapericardial (250 mg) or subcutaneous (50 mg) procaine, plasma procaine levels rose to 9.4 and 4.8 micrograms/ml, respectively. During intravenous infusion of procaine, the PBG chemoreflex was abolished at plasma levels > 3.1 micrograms/ml, and phase 2 of acute hypovolemia at levels > or = 4.3 micrograms/ml. There is a narrow margin between a dose of intrapericardial procaine that blocks cardiac nerves and one that can produce confounding effects from phrenic nerve blockade or absorption into the bloodstream.

Plexus Block

Background and objectivesCervical plexus blocks are commonly used to facilitate carotid endarterectomy (CEA) in the awake patient. These blocks can be divided into superficial, intermediate, and deep blocks by their relation to the fasciae of the neck. We hypothesized that the depth of block would have a significant impact on phrenic nerve blockade and consequently hemi-diaphragmatic motion.MethodsWe enrolled 45 patients in an observer blinded randomized controlled trial, scheduled for elective, awake CEA. Patients received either deep, intermediate, or superficial cervical plexus blocks, using 20 mL of 0.5% ropivacaine mixed with an MRI contrast agent. Before and after placement of the block, transabdominal ultrasound measurements of diaphragmatic movement were performed. Patients underwent MRI of the neck to evaluate spread of the injectate, as well as lung function measurements. The primary outcome was ipsilateral difference of hemi-diaphragmatic motion during forced inspiration between study groups.ResultsPostoperatively, forced inspiration movement of the ipsilateral diaphragm (4.34±1.06, 3.86±1.24, 2.04±1.20 (mean in cm±SD for superficial, intermediate and deep, respectively)) was statistically different between block groups (p<0.001). Differences were also seen during normal inspiration. Lung function, oxygen saturation, complication rates, and patient satisfaction did not differ. MRI studies indicated pronounced permeation across the superficial fascia, but nevertheless easily distinguishable spread of injectate within the targeted compartments.ConclusionsWe studied the characteristics and side effects of cervical plexus blocks by depth of injection. Diaphragmatic dysfunction was most pronounced in the deep cervical plexus block group.Trial registration numberEudraCT 2017-001300-30.

Abstract Diaphragmatic eventration is an anomaly of the diaphragm. In Scimitar syndrome, a curved-shaped anomalous pulmonary venous drainage is seen. Association between these conditions is rare. We present a newborn with diaphragmatic eventration, whose diagnosis of Scimitar syndrome was made after surgical repair. Scimitar syndrome is a congenital disorder often associated with other heart and lungs anomalies. Diagnosis can be fortuitous but with important prognostic features.

Diaphragmatic Eventration

A diaphragmatic eventration is a displacement of abdominal structures into the thoracic cavity, due to weakness and balooning of the diaphragm (Nelson, 1969). In several aspects it has similarities with a diaphragmatic hernia, i.e. the space occupying effects to the lungs, and the sequences of it. An eventration can be divided in 2 groups, the congenital eventration, where the diaphragm is devoid of mucles and only a membrane is separating the abdominal from the pleural cavity; and the acquired one where the phrenic nerve is damaged, usually due to birth injury; but it can also be caused by any other trauma (Bernado et aI., 1961; Bisono et aI., 1970) such as surgical procedures at the time of thoracotomy, the so called iatrogenic  eventration (Jewett et aI., 1964).
