THE NASAL DOUCHE. WHAT IT ACCOMPLISHES AND WHAT IT DOES NOT. BEVERLEY ROBINSON, M. D. THE NASAL DOUCHE: WHAT IT ACCOMPLISHES AND WHAT IT DOES NOT. By BEVERLEY ROBINSON, M. D., SUBGEON TO THE MANHATTAN EYE AND EAB HOSPITAL (DEPAETMENT OF THE THEOAT); PHYSICIAN TO THE DEMILT D1SP1NSAEY, ETC. Read before the New York Medical Library and Journal Association. Since Roosa, Moos, Knapp, Parclee and other well-known specialists have made known to the profession the evil effects upon the organ of hearing which may and do result from the use of Weber’s douche, in ap- plying medicated solutions to the mucous lining of the nasal passages, its employment has become more restricted. A few practitioners, it is true, have persistently denied that unfortu- nate sequelae are ever directly caused by this convenient appliance. Others, more numerous, admit that inflammation of the middle ear, fol- lowed by purulent discharge, may infrequently be occasioned by the douche; but they add that, when properly used, viz., when the patient does not swallow during the period which the operation consumes; when due attention is paid to the temperature and degree of concentration of the solution employed, to the force of the jet of liquid and the duration and frequency of the application, objection to its use are rarely, if ever, valid. Others, again, in their writings, bid their colleagues to beware of em- ploying the nasal douche, no matter how imperative the indication of its use may appear to be, and consider its adoption, as a method of treat- ment, to be ever attended with danger to the ears of the patient. Amongst these latter Professor Roosa stands forth prominently; and as he is of the opinion (Treatise on Disease of the Ear, p. 291) “that its use should be discountenanced by the profession,” no doubt, when his work appeared, many of those physicians who still remained faithful to the douche, abandoped it, though loath to do so, “ as it is thought to be so thorough in its work of cleansing the nostrils and pharynx.” (Loc. cit.) Against this received opinion, which we deem to be a great though generally accepted error, we here desire to enter our protest. The nasal douche does not, in our estimation, do wThat it purports to do, viz., cleanse thoroughly the nasal passage and naso-pharyngeal cavity, but in reality leaves a considerable space untouched by its action. If such be the case, those members of the profession who gave up its use with reluctance need at present have no regrets. We will now endeavor to demonstrate the truth of the above asser- tion. The diameter in all directions of the jet of liquid which flow's from the nozzle of the ordinary Weber’s douche is certainly not more than | to | of an inch. The anterior openings of the cartilaginous por- tion of the nose (nostrils) in the adult, and during normal respiration, are of oval form, and speaking generally, from f to i of an inch in the lateral, and from f to £ in the antero-posterior diameter. The posterior openings are likewise somewhat oval in configuration and about half an inch in the short, or transversal, and 1 inch in the long, or vertical diameter. The depth of the nasal passages at their median portion is nearly double this latter measurement; whereas the lateral diameter in this region measures, upon the floor of the fossa, or interiorly, only six lines, and becomes rapidly narrower as we approach nearer to the roof, or superior part of the nose, where it has only about 1 line. This lateral diameter does not vary much anteroposteriorly, but re- mains nearly the same on a given horizontal plane. These data being accepted as true, let us see how the douche acts. When the nozzle is introduced into one of the anterior openings of the nose, and the stream begins to flow, but a few seconds usually elapse before a jet of water of like calibre with the entering one makes its exit from the opposite nos- tril. Now, the physiological fact upon which the use of Weber’s douche is based is, that one side of the nasal and the entire naso-pharyngeal cavity being'filled with liquid by hydrostatic pressure, the soft palate is raised up by the contraction of the levatores palati muscles, and perfect coaptation between its posterior border and the walls of the pharynx is effected, and thus the passage-way for the escape of any quantity of liquid dowmvards into the pharynx is completely intercepted. The in- jected liquid must, therefore, of necessity, make its exit by the other side of the nasal passages, and in doing so comes in contact with all the parts contained in or limiting the side of these cavities through which the stream enters. To this we reply that if, during the operation, one-half the nasal pas- sage, and the entire naso-pharyngeal space were flooded with liquid, we doubt not that the whole of the interior of these cavities would be cleansed and rinsed very completely. But, practically, is this often or ever the case ? Wo put aside temporarily, without considerin'" them, those cases in which the passages are so much obstructed by the swollen and infiltrated condition of the mucous membyane, or from some other cause, that the stream either cannot pass, or flows slowly and imperfectly; and we would draw attention to the following propositions 1. Inasmuch as in the majority of cases the column of water escapes in equal volume, and with as great force and rapidity as the entering jet, how can the passages be flooded ? 2. Water naturally seeks its level, and when it can pass freely around the posterior border of the nasal septum, how can it be made evident that it goes so far upward as the vault of the pharynx, or penetrates to the depth of the nasal cavities ? S. We must remember that, in using the douche, the patient is told to bend his head over a basin or receptacle for containing the issuing liquid. The floor of the nasal passages thus becomes a plane inclined forwards and downwards, and the medicated solution employed has by the mere force of gravity, an impelling tendency to go around the septum narium and flow out by the lower meatus. We may now return to the cases where the passages are greatly ob- structed ; and, first, we question whether—and though the calibre of the stream be sufficient to fill up one of the anterior openings of the nares, and be used under the condition of hydrostatic pressure ordinarily em- ployed with the douche—whether we say, in like case the remaining portion of the side of the nasal cavities by which the stream of liquid flows in would be entirely filled. When we penetrate a short distance into these cavities their dimensions are greater in the different diameters than those of the anterior nares, and with similar calibre of orifice of exit to orifice of entrance, both being placed on the same level, the li- quid must take the shortest and most direct road towards the opening of escape outwards. If, however, the force and rapidity of the current be very great, and if owing to excess of obstruction on the opposite side to that of the enter- ing fluid, this latter cannot so quickly leave the nasal passages as it flows into them, one side, at least, of these cavities may be entirely filled with liquid; but even in that case it would only be during a few seconds. For. admitting the possibility of the case supposed, is it not apparent that the subjective sensations of the patient would become so unpleasant, or the pressure in the nasal cavities and naso-pharyngeal space be such that the soft palate would give way almost immediately. Some liquid would then pass into the stomach by an effort of deglutr tion, or else, owing to confused breathing, get into the larynx and pro- duce a violent paroxysm of cough. In the last-mentioned event the whole of the inflowing liquid would be violently rejected through the mouth and nose, whilst the operation itself would of necessity be sud- denly interrupted. We do not believe, therefore, for our part, that either the vault of the pharynx, the superior and middle turbinated bones, or the superior meatus, are cleansed at all by the nasal douche. True it is that a great deal of inspissated mucus, hard crusts, and soft, fetid secretions, are frequently brought away; and we were disposed, for a long while, to console ourselves in the belief that the nasal cavities were effectually rinsed at the termination of each operation. Experience, however, has taught us the fallacy of such a belief; and now that we inspect the nares, anteriorly after one of these washings, and, what is still better, make a rhinoscopic examination posteriorly, when it is possible, we find at times there still remains at the top of the pharynx, or around and con- tained in the posterior openings of the nose, strings of viscid mucus which have been left untouched. Whenever this proof is wanting wre shall have to consider the striking clinical fact of a crust or large muscle shaped bit of mucus being expelled from the nose after what we inferred wrongly had been a most complete cleansing. The explanation of this phenomenon is readily found. Large pieces of mucus have become detached from the roof of the nose, and more particularly from the cribriform plate of the ethmoid bone, the posterior surface of the nasal bones, and the upper turbinated bones, owing, no doubt, to increased temporary secretion, brought on by the use of the douche, and have fallen to the floor of the nasal cavities. Here they have been the occasion of more or less unpleasant and abnormal sensa- tions, and a strong effort of expiration is sufficient to expel or throw them off altogether. Whilst much of the irritating and concrete mucus is thus got rid of, a certain amount remains behind, and, by the morbid alterations which it assumes, is the source of further disease, or, at all events, by its constant contact with parts already diseased, protracts or renders impossible the return of these latter to their normal state. We would not have our readers believe that the foregoing remarks originated wholly with ourselves. They have been suggested partly by the perusal of an interesting communication from the pen of Thomas F. Rumbold, M. D.,which appeared in the number for September, 1873, of the St. Louis Medical and Surgical Journal, partly by a short article in Archiv. fur Ohrenheilkunde (vi. Bd. 4 Heft, 1873), by Ludwig Schultze, of Leipzig, and partly, we feel free to add, by our own individual thought and experience. The subject of these brief remarks is assuredly one worthy of attention. Affections of the nose are not infrequent with us. Nasal catarrh es- pecially is met with each day and on all sides. It becomes, therefore, the duty of every practitioner of medicine, and not merely of the specialist in diseases of the throat and nose, to know how this last-mentioned and other analogous affections may be treated prudently and efficaciously; and true it is, unfortunately, the treatment of them has hitherto been most unsatisfactory. So much is this the rule, in point of fact, that already, amongst unprofessional persons, “catarrh ” is classed with other “opprobria medicorum.” May not the secret of this lack of successful therapeutics be found in the statement, we ask, that thus far no instrument has come into general use which meets the one evidently essential indication in the treatment of every case, viz., to thoroughly cleanse the entire nasal cavities. 15 West 26th steeet.
