See accompanying table.caudal block caudal anesthesia.cervical plexus block anesthesia" >regional anesthesia of the neck by injection of a local anesthetic into the plexus" >cervical plexus.entrance block a zone of depressed conduction surrounding a pacemaker focus, protecting it from discharge by an extraneous impulse but not necessarily from discharges by electrotonic influences.epidural block epidural anesthesia.exit block heart block characterized by failure of an expected impulse to emerge from its focus of origin and propagate; this usually occurs with a parasystolic focus, but is also seen with sinus, junctional, and ventricular rhythms. In cardiac pacing it means that the pacemaker stimulus is not of sufficient amplitude to stimulate the heart, such as when there is a very high threshold.fascicular block heart block characterized by certain abnormal QRS waveforms ascribed to conduction disturbance in the anterior and posterior divisions of the left bundle branch.fascicular block, left anterior heart block characterized by delay or interruption of impulse conduction in the anterior superior division of the left bundle branch, resulting in asynchronous activation of the left ventricle.fascicular block, left posterior heart block characterized by delay or interruption of impulse conduction in the posterior inferior division of the left bundle branch, resulting in asynchronous activation of the left ventricle.femoral block anesthesia" >regional anesthesia of the posterior thigh and the lower leg by injection of a local anesthetic around the femoral nerve just below the inguinal ligament at the lateral border of the fossa ovalis.field block anesthesia" >regional anesthesia by blocking conduction in nerves with chemical or physical agents.heart block see heart block.intravenous block Bier block.intraventricular block impaired conduction within the ventricles due to absence of conduction within the bundle branches, their ramifications, or the ventricles.intraventricular block, unspecified any heart block characterized by an electrocardiographic pattern of intraventricular conduction disturbance and not qualifying as a bundle branch block or a fascicular block.interventricular block bundle branch block.IV block Bier block.lumbar plexus block anesthesia" >regional anesthesia of the anterior and medial aspects of the lower limb by injection of a local anesthetic into the plexus" >lumbar plexus.mental block blocking (def. 3).metabolic block the blocking of a biosynthetic pathway due to a genetic enzyme defect or to inhibition of an enzyme by a drug or other substance.Mobitz type I block a second degree atrioventricular block in which the P-R interval increases progressively until an atrial impulse is blocked. Called also Wenckebach's phenomenon or block.Mobitz type II block a second degree atrioventricular block in which the P-R interval is fixed, with periodic blocking of the atrial impulse to the ventricle.nerve block anesthesia" >regional anesthesia by injection of an anesthetic close to the appropriate nerve.paracervical block anesthesia" >regional anesthesia of the inferior hypogastric plexus and ganglia produced by injection of the local anesthetic into the lateral fornices of the vagina.paraneural block perineural block.parasacral block anesthesia" >regional anesthesia by injection of a local anesthetic around the sacral nerves as they emerge from the sacral foramina.paravertebral block paravertebral anesthesia.perineural block anesthesia" >regional anesthesia produced by injection of the anesthetic agent close to the nerve. Called also paraneural anesthesia or block and perineural anesthesia.presacral block anesthesia" >regional anesthesia produced by injection of the local anesthetic into the sacral nerves on the anterior aspect of the sacrum.pudendal block anesthesia" >regional anesthesia produced by blocking the pudendal nerves, accomplished by injection of the local anesthetic into the tuberosity of the ischium.

The pudendal block. The pudendal nerves can be effectively blocked by a local anesthetic, thereby anesthetizing the perineum. From Nichols and Zwelling, 1997.retrobulbar block that performed by injection of a local anesthetic into the retrobulbar space to anesthetize and immobilize the eye.sacral block anesthesia" >regional anesthesia produced by injection of the local anesthetic into the extradural space of the spinal canal.saddle block anesthesia" >regional anesthesia in an area corresponding roughly with the areas of the buttocks, perineum, and inner aspects of the thighs, by introducing the anesthetic agent low in the dural sac. Called also saddle block anesthesia.sinoatrial block a type of heart block characterized by partial or complete interference with the propagation of impulses from the sinoatrial node to the atria, resulting in delay or absence of the atrial response.sinus block barosinusitis.sinoatrial block.spinal block spinal anesthesia.subarachnoid block spinal anesthesia (def. 2).trifascicular block an imprecise term referring to heart block characterized by failure of conduction, partial or complete, in all three of the fascicles of the intraventricular conduction system; i.e., there is simultaneous right bundle branch block, left anterior hemiblock, and left posterior hemiblock. In the setting of acute anterior wall myocardial infarction, this is an ominous sign. More precise terms referring to the specifically involved structures are preferred.vagal block (vagus nerve block) anesthesia" >regional anesthesia produced by blocking of vagal impulses by injection of a solution of local anesthetic into the vagus nerve at its exit from the skull.Wenckebach block Mobitz type I block.wrist block anesthesia" >regional anesthesia of the hand by injection of a local anesthetic around the median, radial, and ulnar nerves at the wrist.

Patient discussion about block

Q. what does a sun block cream do? and what are a UV rays? A. It blocks out harmful Ultra violet rays from the skin as the previous entries have related; however it can also block your ability to produce vitamin D. If you live in a northerly area or one that receives limited sunlight, its recommended to get at least 15 minutes of sun a day (this is probably best done with minimal sunblock) and according to personnal sun sensitivity. Another thing to keep in mind is that sunblock works best if applied 20 minutes before sun exposure.

Q. my son is 5 and half yrs old.he is having veezing and 75%block in one nose because of adenod.is is curable he has taken steriods for one and half yrs but with not much relief for veezing. then we switched on to ayur medicines,where he had some pigmentation at some places in his body. so again we are back to allopathy. he has one nasal steriod spray now with few other medicines. in his last test, dr, said he has adenod about 75% blcok in one nose, he has prescribed medicines for one month. he has also said that a small surgery can be done to remove adenod. i would like to know how long this surgry wil take and how much of rest he wil have to take. and if this adenod is removed, wil his other problem like veezing be cured? indira rajeshA. it's a pretty common surgery from what i remember. most of our family has any kind of nasal problem...sinusitis..adenoids...just name it. the surgery is entering through the mouth (under full sedation) and lasering/curetting - removed. it took about a week to recover , eating soft foods..and it worked!
