Will It Hurt?

“. . . the children’s population of this century has been submitted progressively as never before to the merciless routine of the ‘cold steel’ of the hypodermic needle.”  —Karl E. Kassowitz, “Psychodynamic Reactions of Children to the Use of Hypodermic Needles” (1958)

Of course, like so much medical technology, injection by hypodermic needle  has a prehistory dating back to the ancient Romans, who used metal syringes with disk plungers for enemas and nasal injections.  Seventeenth- and eighteenth-century physicians extended the sites of entry to the vagina and rectum, using syringes of metal, pewter, ivory, and wood.  Christopher Wren, the Oxford astronomer and architect, introduced intravenous injection in 1657, when he inserted a quill into the patient’s exposed vein and pumped in water, opium, or a purgative (laxative).

But, like so much medical technology, things only get interesting in the nineteenth century.  In the first half of the century, the prehistory of needle injection includes the  work of G. V. Lafargue, a French physician from the commune of St. Emilion.  He treated neuralgic (nerve) pain – his own included – by penetrating the skin with a vaccination lancet dipped in morphine and later by inserting solid morphine pellets under the skin through a large needle hole.  In 1844, the Irish physician Francis Rynd undertook injection by making a small incision in the skin and inserting a fine cannula (tube), letting gravity guide the medication to its intended site.[1]

The leap to a prototype of the modern syringe, in which a glass piston pushes medicine through a metal or glass barrel that ends in a hollow-pointed needle, occurred on two national fronts in 1853.  In Scotland, Alexander Wood,  secretary of Edinburgh’s Royal College of Physicians, injected morphine solution directly into his patients in the hope of dulling their neuralgias.  There was a minor innovation and a major one.  Wood used sherry wine as his solvent, believing it would prove less irritating to the skin than alcohol and less likely to rust his instrument than water.  And then the breakthrough:  He administered the liquid morphine through a piston-equipped syringe that ended in a pointed needle.  Near the end of the needle, on one side, was an  opening through which medicine could be released when an aperture on the outer tube was rotated into alignment with the opening.  It was designed and made by the London instrument maker Daniel Ferguson, whose “elegant little syringes,” as Wood described them, were intended to inject iron percholoride (a blood-clotting agent, or coagulant) into skin lesions and birthmarks in the hope of making them less unsightly.  It never occurred to him that his medicine-releasing, needle-pointed syringes could be used for subcutaneous injection as well.[2]

Across the channel in the French city of Lyon, the veterinary surgeon Charles Pravez employed a piston-driven syringe of his own making to inject iron percholoride into the blood vessels of sheep and horses.  Pravez was not interested in unsightly birthmarks; he was searching for an effective treatment for aneurysms (enlarged arteries, usually due to weakening of the arterial walls) that he thought could be extended to humans.  Wood was the first in print – his “New Method of Treating  Neuralgia by the Direct Application of Opiates to the Painful Points” appeared in the Edinburgh Medical & Surgical Journal in 1855[3] — and, shortly thereafter, he improved Ferguson’s design by devising a hollow needle that could simply be screwed onto the end of the syringe.  Unsurprisingly, then, he has received the lion’s share of credit for “inventing” the modern hypodermic syringe.  Pravez, after all, was only interested in determining whether iron percholoride would clot blood; he never administered medication through his syringe to animals or people.

Wood and followers like the New York physician Benjamin Fordyce Barker, who brought Wood’s technique to Bellevue Hospital in 1856, were convinced that the injected fluid had a local action on inflamed peripheral nerves.  Wood allowed for a secondary effect through absorption into the bloodstream, but believed the local action accounted for the injection’s rapid relief of pain.  It fell to the London surgeon Charles Hunter to stress that the systemic effect of injectable narcotic was primary.  It was not necessary, he argued in 1858, to inject liquid morphine into the most painful spot; the medicine provided the same relief when injected far from the site of the lesion.  It was Hunter, seeking to underscore the originality of his approach to injectable morphine, especially its general therapeutic effect, who introduced the term “hypodermic” from the Greek compound meaning “under the skin.”[4]

It took time for the needle to become integral to doctors and doctoring.  In America, physicians greeted the hypodermic injection with skepticism and even dread, despite the avowals of patients that injectable morphine provided them with instantaneous, well-nigh miraculous relief from chronic pain.[5]  The complicated, time-consuming process of preparing injectable solutions prior to the manufacture of dissolvable tablets in the 1880s didn’t help matters.  Nor did the trial-and-error process of arriving at something like appropriate doses of the solutions.  But most importantly, until the early twentieth century, very few drugs were injectable.  Through the 1870s, the physician’s injectable arsenal consisted of highly poisonous (in pure form) plant alkaloids such as morphine, atropine (belladonna), strychnine, and aconitine, and, by decade’s end, the vasodilator heart medicine nitroglycerine.  The development of local and regional anesthesia in the mid-1880s relied on the hypodermic syringe for subcutaneous injections of cocaine solution, but as late as 1905, only 20 of the 1,039 drugs in the U.S. Pharmacopoeia were injectable.[6]  The availability of injectable insulin in the early 1920s heralded a new, everyday reliance on hypodermic injections, and over the course of the century, the needle, along with the stethoscope, came to stand in for the physician.  Now, of course, needles and doctors “seem to go together,” with the former signifying “the power to heal through hurting” even as it “condenses the notions of active practitioner and passive patient.”[7]

The child’s fear of needles, always a part of pediatric practice, has generated a literature of its own.  In the mid-twentieth century, in the heyday of Freudianism, children’s needle anxiety gave rise to psychodynamic musings.  In 1958, Karl Kassowitz of Milwaukee Children’s Hospital made the stunningly commonsensical observation that younger children were immature and hence more anxious about receiving injections than older children.  By the time kids were eight or nine, he found, most had outgrown their fear.  Among the less than 30% who hadn’t, Kassowitz gravely counseled, continuing resistance to the needle might represent “a clue to an underlying neurosis.”[8]  Ah, the good old Freudian days.

In the second half of the last century, anxiety about receiving injections was “medicalized” like most everything else, and in the more enveloping guise of BII (blood, injection, injury) phobia, found its way into the fourth edition of the American Psychiatric Association’s Diagnostic and Statistical Manual in 1994. Needle phobia thereupon became the beneficiary of all that accompanies medicalization – a specific etiology, physical symptoms, associated EKG and stress hormone changes, and strategies of management.  The latter are impressively varied and range across medical, educational, psychotherapeutic, behavioral, cognitive-behavioral, relaxation, and desensitizing approaches.[9]  Recent literature also highlights the vasovagal reflex associated with needle and blood phobia.  Patients confronted with the needle become so anxious that an initial increase in heart rate and blood pressure is followed by a marked drop,   as a result of which they become sweaty, dizzy, pallid, nauseous (any or all of the above), and sometimes faint (vasovagal syncope).  Another interesting finding is that needle phobia (especially in its BII variant) along with its associated vasovagal reflex probably have a genetic component, as there is a much higher concordance within families for BII phobia than other kinds of phobia. Researchers who study twins put the heritability of BII phobia at around 48%.[10]

Needle phobia is still prevalent among kids, to be sure, but it has long since matured into a fully grown-up condition. Surveys find injection phobia in anywhere from nine to 21% of the the general population and even higher percentages of select populations, such as U.S. college communities.[11]               A study by the Dental Fears Research Clinic of the University of                               Washington in 1995 found that over a quarter of surveyed students and university employees were fearful of dental injections, with 5% admitting they avoided or canceled dental appointments out of fear.[12]  Perhaps some of these needlephobes bear the scars of childhood trauma.  Pediatricians now urge control of the pain associated with venipuncture and intravenous cannulation (tube insertion) in infants, toddlers, and young children, since there is evidence such procedures can have a lasting impact on pain sensitivity and tolerance of needle picks.[13]

But people are not only afraid of needles; they also overvalue them and seek them out.  Needle phobia, whatever its hereditary contribution, is a creation of Western medicine.  The surveys cited above come from the U.S., Canada, and England.  Once we shift our gaze to developing countries of Asia and Africa we behold a different needle-strewn landscape.  Studies attest not only to the high acceptance of the needle but also to its integration into popular understandings of disease.  Lay people in countries such as Indonesia, Tanzania, and Uganda typically want injections; indeed, they often insist on them because injected medicines, which enter the bloodstream directly and (so they believe) remain in the body longer, must be more effective than orally injected pills or liquids.

The strength, rapid action, and body-wide circulation of injectable medicine – these things make injection the only cure for serious disease.[14]  So valued are needles and syringes in developing countries that most lay people, and even Registered Medical Practitioners in India and Nepal, consider it wasteful to discard disposable needles after only a single use.  And then there is the tendency of people in developing countries to rely on lay injectors (the “needle curers” of Uganda; the “injection doctors” of Thailand; the informal providers of India and Turkey) for their shots.  This has led to the indiscriminate use of  penicillin and other chemotherapeutic agents, often injected without attention to sterile procedure.  All of which contributes to the spread of infectious disease and presents a major headache for the World Health Organization.

The pain of the injection?  Bring it on.  In developing countries, the burning sensation that accompanies many injections signifies curative power.  In some cultures, people also welcome the pain as confirmation that real treatment has been given.[15]  In pain there is healing power.  It is the potent sting of modern science brought to bear on serious, often debilitating disease.  All of which suggests the contrasting worldviews and emotional tonalities collapsed into the fearful and hopeful question that frames this essay:  “Will it hurt?”

Your Tool Touches Me

It is little known that René Laënnec, the Parisian physician who invented the stethoscope at the Necker Hospital in 1816, found it distasteful to place his ear to the patient’s chest.  The distastefulness of “direct auscultation” was compounded by its impracticality in the hospital where, he observed, “it was scarcely to be suggested for most women patients, in some of whom the size of the breasts also posed a physical obstacle.”[1]  The stethoscope, which permitted “mediate auscultation,” not only amplified heart and lung sounds in diagnostically transformative ways; it enabled Laënnec to avoid repugnant  ear to chest contact.

Many women patients of Laënnec’s time and place did not see it that way.  Accustomed to the warmly human pressure of ear on chest, they were uncomfortable when an elongated wooden cylinder was interposed between the two.  By the closing decades of the nineteenth century, of course, the situation was inverted:  The stethoscope, in its modern binaural guise, had become so integral to physical examination that patients  hardly viewed it as a tool at all.  It had become emblematic of hands-on doctoring and, as such, a sensory extender of the doctor.  Even now, the stethoscope virtually stands in for the doctor, especially the generalist or the cardiologist, so that a retiring physician will announce that he is, or will be characterized by others as, hanging up his stethoscope.[2]

It’s easy to argue for the “oneness” of the physician and his or her instruments when it’s a matter of simple tools that amplify sensory endowment  (stethoscopes), provide a hands-on bodily “reading” (of temperature or blood pressure), or elicit a tendon reflex (e.g., the reflex hammer).  And the argument can be extended without much difficulty to the more invasive, high-tech “scopes” used by medical specialists to see what is invisible to the naked eye.  Instruments become so wedded to one or another specialty that it is hard to think of our providers without them.  What is an ophthalmologist without her ophthalmoscope?  An ENT without his nasal speculum?  A gynecologist without her vaginal speculum?  An internist without his blood pressure meter?  Such hand-held devices are diagnostic enablers, and as such they are, or at least ought to be, our friends.

In “Caring Technology” I  suggested that even large-scale technology administered by technicians, and therefore outside the physician’s literal grasp, can be linked in meaningful ways to the physician’s person.  A caring explanation of the need for this or that study, informed by a relational bond, can humanize even the most forbidding high-tech machinery.  To be sure, medical machinery, whatever the discomfort and/or bodily bombardment it entails, is often discomfiting.  But it need be alienating only when we come to it in an alienated state, when it is not an instrument of physicianly engagement but a dehumanized object – a piece of technology.

Critical care nurses, whose work is both technology-laden and technology-driven, have had much to say on the relationship of technology to nursing identity and nursing care.  This literature includes provocative contributions that look at where nurses stand in a hospital hierarchy that comprises staff physicians, residents, students, administrators, patients, and patients’ families.

For some CCU nurses, the use of technology and the acquisition of technological competence segue into issues of power and autonomy and they, in turn, are linked to issues of gender, medical domination, and “ownership” of the technology.[3]  A less feminist sensibility informs interview research that yields unsurprising empirical findings, viz.,  that comfort with technology and the ability to incorporate it into a caring, “touching” disposition hinge on the technological mastery associated with nursing experience.  Student and novice nurses, for example, find the machinery of the CCU anxiety-inducing, even overwhelming.  They resent the casual manner in which physicians relegate to them complex technological tasks, such as weaning patients from respirators, without appreciating the long list of  nursing duties to which such tasks are appended.[4]  Withal, beginners approach the use of technology in task-specific ways and have great difficulty “caring with technology.”[5]   Theirs is not a caring technology but a technology that causes stress and jeopardizes fragile professional identities.

Experienced CCU nurses, on the other hand, achieve a technological competence that lets them pull the machinery to them; they use it as a window of opportunity for being with their patients.[6]   Following Christine Little, we can give the transformation from novice to expert a phenomenological gloss and say that as technological inexperience gives way to technological mastery, technological skills become “ready-to-hand” (Heidegger) and “a natural extension of practice.”[7]

Well and good.  We want critical care nurses comfortable with the machinery of critical care – with cardiac and vital signs monitors, respirators, catheters, and infusion pumps – so that implementing technological interventions and monitoring the monitors do not blot out the nurse’s “presence”  in the patient’s care.   But all this is from the perspective of the nurse and her role in the hospital.  What, one wonders, does the patient make of all this technology?

Humanizing technology means identifying with it in ways that are not only responsive to the patient’s fears but also conducive to a shared appreciation of its role in treatment.  It is easier for patients to feel humanly touched by technology, that is, if their doctors and nurses appropriate it and represent it as an extender of care.  Perhaps some doctors and nurses do so as a matter of course, but one searches the literature in vain for examples of nurse-patient or doctor-patient interactions that humanize technology through dialogue.  And such dialogue, however perfunctory in nature, may greatly matter.

Consider the seriously ill patient whose nurse interacts with him without consideration of the technology-saturated environment in which care is given.  Now consider the seriously ill patient whose nurse incorporates the machinery into his or her caregiving identity, as in “This monitor [or this line or this pump] is a terrific thing for you and for me.  It lets me take better care of you.”  Such reassurance, which can be elaborated in any number of patient-centered ways, is not trivial; it may turn an anxious patient around, psychologically speaking.  And it is all the more important when, owing to the gravity of the patient’s condition, the nurse must spend more time assessing data and tending to machinery than caring for the patient.  Here especially the patient needs to be reminded that the nurse’s responsibility for machinery expands his or her role as the patient’s guardian.[8]

The touch of the physician’s sensory extenders, if literally uncomfortable, may still be comforting.  For it is the physician’s own ears that hear us through the stethoscope and whose own eyes gaze on us through the ophthalmoscope, the laryngoscope, the esophagoscope, the colposcope.  It is easier to appreciate tools as beneficent extenders of care in the safe confines of one’s own doctor’s office, where instrumental touching is fortified by the relational bond that grows out of continuing care.  In the hospital, absent such relational grounding, there is  more room for dissonance and hence more need for shared values and empathy.  A nurse who lets the cardiac monitor pull her away from patient care will not do well with a frightened patient who needs personal caring.  A parturient who welcomes the technology of the labor room will connect better with a labor nurse who values the electronic fetal monitor (and the reassuring visualization it provides the soon-to-be mother) than a nurse who is unhappy with its employment in low-risk births and prefers a return to intermittent auscultation.

In the best of circumstances, tools elicit an intersubjective convergence grounded in an expectation of objectively superior care.  It helps to keep the “objective care” part in mind, to remember that technology was not devised to frighten us, encumber us, or cause us pain,  but to help doctors and nurses evaluate us, keep us stable and comfortable, and enable treatments that will make us better, or at least leave us better off than our technology-free forebears.

My retinologist reclines the examination chair all the way back and begins prepping my left eye for its second intravitreal  injection of Eylea, one of the newest drugs used to treat macular disease.  I am grateful for all the technology that has brought me to this point:  the retinal camera, the slit lamp, the optical coherence tomography machine.  I am especially grateful for the development of fluorescein angiography, which allows my doctor to pinpoint with great precision the lesion in need of treatment.  And of course I am grateful to my retinologist, who brings all this technology to bear with a human touch, calmly reassuring me through every step of evaluation and treatment.

I experienced almost immediate improvement after the first such injection a month earlier and am eager to proceed with the treatment.  So I am relatively relaxed as he douses my eye with antiseptic and anesthetic washes in preparation for the needle.  Then, at the point of injection, he asks me to look up at the face of his assistant, a young woman with a lovely smile.  “My pleasure,” I quip, slipping into gendered mode.  “I love to look at pretty faces.”   I am barely aware of the momentary pressure of the needle that punctures my eyeball and releases this wonderfully effective new drug into the back of my eye.  It is not the needle that administers treatment but my trusted and caring physician.  “Great technique,” I remark.  “I barely felt it.”  To which his young assistant, still standing above me, smiles and adds,  “I think I had something to do with it.”  And indeed she had.
