Bloqueo del Ganglio Esfenopalatino como tratamiento para la neuralgia esfenopalatina con expresión del Glosofaríngeo / Sphenopalatine ganglion blockade for sphenopalatine neuralgia with glossopharyngeal expression

La historia del bloqueo nervioso del ganglio esfenopalatino data de 1908, cuando Greenfield Sluder, describió por primera vez al tratamiento de una variedad de cefaleas y síntomas de dolor facial a través del bloqueo del ganglio con anestésicos locales. Esta técnica también ha sido útil en el tratamiento de migraña, cefaleas y Síndrome de Dolor Facial Atípico. En este estudio se realizó una revisión retrospectiva de tres casos, dos mujeres y un hombre, con un rango de edad de 36-47 años, con antecedentes de Rinitis Alérgica y cuadros gripales crónicos. En los 3 casos, los pacientes presentaban sintomatología de neuralgia esfenopalatina con componente de neuralgia glosofaríngea, tales como: odinofagia, rinorrea, lagrimeo unilateral, refiriendo episodios de dolor laríngeo súbito, a la deglución (en dos casos) y seguido de un acceso de tos (un caso), tipo punzante, paroxístico, con duración de segundos, sin predominio de horario, con mala respuesta a tratamiento farmacológico a base de carbamazepina. Dicha sintomatología se fue incrementando en frecuencia e intensidad. En los 3 casos, se realizó bloqueo del ganglio esfenopalatino analgésico-desinflamatorio, diangóstico-pronóstico, presentando mejoría hasta la remisión total de los síntomas clínicos

permeability of the enteric ganglia of the guinea-pig distal colon to intravenously injected horseradish peroxidase

In this work, the permeability of the "Capsule" of enteric ganglia to intravenously injected horseradish peroxidase [HRP] has been studied in the guinea-pig distal colon. The study was conducted at 30, 90 minutes and 6 hours following injection. HRP rapidly penetrated the walls of submucosal blood vessels and to a must lesser extent those of the myenteric zone. HRP reaction product was subsequently found more within the submucous ganglia than within the myenteric ganglia. HRP within both types of ganglia was more prominent 6 hours following injection

Prevention of oculocardiac reflex (O.C.R) during extraocular muscle surgery.

In the present study the effectiveness of intravenous atropine sulphate which blocks the peripheral muscarinic receptors at the heart and retrobulbar xylocaine hydrochloride which blocks the conduction at ciliary ganglion on the afferent limb of OCR was studied during strabismus surgery. The study was conducted on fifty three patients of either sex having squint of more than ten years duration. The patients were randomly allocated into four groups. No preanaesthetic medication with atropine or retrobulbar block with xylocaine was given in control group of patients. In the second group, only preanaesthetic medication with atropine was given; while in the third group only retrobulbar injection of xylocaine was given five minutes before operation. In the last group both atropine as preanaesthetic medication and xylocaine as retrobulbar block were given. The electrocardiographic recordings were taken before and throughout the operative procedure. It was interesting to note that in the group where atropine and xylocaine were used none of the patients exhibited activation of OCR. Results have been discussed.
