Opiates for pain in dying patients and in those with sickle cell disease

Opiates for pain in dying patients and in those with sickle cell disease

Dorothy Logie and Mhoira Leng’s report of 6 October describes a conference in Nairobi which highlighted opiophobia – the fear of using morphine therapeutically – “as a big obstacle facing palliative care services in the (African) continent” [1]. The conference was concerned with dying patients. In his rapid response, however, Jecko Thachil concentrated on the use of opiates in sickle cell disease patients. He states that while “very high amounts of opiates (often in hundreds of milligrams) are often required for the patients who suffer from recurrent sickle crises” [2], the expected analgesic effect leaves much to be desired, not to mention side-effects. Dealing with terminally ill patients is one thing; opiate administration to sickle cell disease patients is something else entirely.

Dr Thachil feels an “increased need for additional education regarding sickle cell disease…” Has he examined the experiences of two physicians who personally supervised thousands of people with sickle cell disease on both sides of the Atlantic continuously for years? [3, 4] Treating sickle cell disease is not the same as managing the sickle cell disease patient [5]; the difference in the two approaches tending to separate haematologists on the one hand, from physicians and family practitioners on the other. When a white British consultant physician in a London teaching hospital complained that “the haematologists here have created a cohort of addicts” [6] a white consultant haematologist in another London teaching hospital tore strips off him, accusing him of being a racist for depriving suffering black patients of pain relief, an attack which made me respond thus: “White physicians who, at the risk of being misunderstood by (that haematologist), voice their displeasure at what they see happening on their wards deserve commendation, not condemnation” [7].

Not far from where Dr Jacko Thachil works, also on Merseyside, “during a ward round in a provincial teaching hospital with consultant haematologists on March 6, 1997, I was shown a woman who had been on continuous opiate infusion since September, 1996” [7]. I went on to say in my Lancet communication: “Far from the consultants taking umbrage because I pointed out that the patient could not have been in sickle cell crisis for 6 months, they were happy to discuss with me the way forward” [7]. Dr Thachil feels “an increased need for additional education regarding …addiction to pain medication…and treatment of pain” and he concludes “but who and where these should be focussed on is a matter for debate” [2].

Not a matter for debate at all in my opinion: May I suggest to him certain facts he might wish to probe in his quest for education?

(a) “In Jamaican experience ..morphia or its derivatives are rarely used or necessary” [8] How did Graham Serjeant achieve this?

(b) “Most painful crises may be treated in a day-care centre, the patient returning home in the evening” [9] How is this possible if hooked up on morphine or diamorphine pump “as in the recommended UK protocol”? [6]

(c) “We are convinced that the chest syndrome in the UK and the USA is not entirely unrelated to the routine use of opiates in those countries for sickle cell crises”. [10] Some nurses I am in touch with can write an MSc thesis on this.

(d) Goodman from the USA (where diamorphine is banned for patients) found the use of ketorolac in painful sickle cell crises as efficient as morphine but without the latter’s respiratory depression [11]. So why do British haematologists prefer to use morphine and diamorphine? Answer: “Ketorolac has no product licence in the UK for this indication” [12]

(e) Two questions that I have asked British Haematologists several times but which have never been answered, and which Dr Thachil may now ask the National Institute of Clinical Excellence (NICE) for help in answering:

(i) “Why do West African and West Indian patients with sickle cell disease who did without morphine in their countries have to be given morphine pumps during sickle cell crises when they come to the United Kingdom?” [6, 13]

(ii) If pain from whatever cause deserved the most potent analgesic, and dysmenorrhoea has been known to be intolerably painful, would a British haematologist “not consider it unwise for a hospital to administer diamorphine as routine management of young women?” [7]

Four encouraging signs have emerged in the UK since I have been voicing my displeasure at the use of diamorphine and morphine pumps for patients with sickle cell crises: (1) Some haematologists in the UK and the European continent have abandoned the practice in spite of what the ‘approved protocol’ displays in the emergency rooms. (2) Some sickle cell disease patients have become more vocal in their displeasure of the practice. To them ‘opiophobia’ is not to be condemned [1], but commended. (3) Some family practitioners are looking after their patients at home, using intravenous fluids and other than powerfully addictive opiates to help these patients instead of submitting them to hospital care. (4) A clearer grasp of the causes of crisis has put more emphasis on public health measures (fluids, warmth, treatment of infections, dressing properly, anticipating hazards, immunisations, avoiding tobacco and alcohol), enabling patients prevent crises and helping them use the excellent non-sickling genes they have inherited from their parents to achieve as much of their full potential intellectually as possible [10].

It is therefore not surprising to find that the sickle cell disease patients who have become lawyers, teachers, businessmen and women, nurses & midwives, pharmacists, and even doctors are those whose haematologists have abandoned the opiate culture. Occasionally, however, one found even professors of haematology who would defend the prescribing of diamorphine for a sickle cell disease patient with severe difficulty in breathing. “Chest syndrome” was always there to blame, if the patient died [6].

When in my genetic counselling and family size limitation (GCFSL) drive in Ghana and in the Ghanaian community here in the UK I sense that the urgency of my message is being glossed over I tell my fellow countrymen and women in plain language that if they continue to procreate at the rate they are doing, and more sickle cell disease (ACHE/ACHE) patients are born, the chances are that in the UK they may end up on a heroin drip. This concentrates the mind, and they listen to me. “One in three of you is a NORM/ACHE. Do you want to end up with ACHE/ACHE children who will be given heroin for pain?” [http://www.konotey- ahulu.com/diagram.asp]
