Hyperbaric oxygen therapy in the treatment of sickle cell leg ulcers is a 1991 journal article by Rudge FW, published in J. Hyperbaric Med 6(1). It addresses the use of oxygen under increased pressure for ulcers associated with sickle cell disease, a subject relevant to hyperbaric clinicians and to divers because it connects oxygen physiology with a complex blood disorder.

Why do sickle cell disease and leg ulcers intersect?

Sickle cell disease affects haemoglobin, the protein in red blood cells that carries oxygen. Under conditions such as low oxygen tension, red cells containing sickle haemoglobin can change shape, become less flexible and obstruct small blood vessels. This impairs blood flow and can injure tissue.

Leg ulcers are among the complications associated with sickle cell disease. Their development and persistence can involve reduced local perfusion, tissue oxygen shortage and impaired repair. An ulcer is not simply a surface wound: its course may reflect both local tissue conditions and the underlying blood disorder.

What does hyperbaric oxygen therapy change?

Hyperbaric oxygen therapy exposes a patient to oxygen at a pressure above normal atmospheric pressure, generally in a purpose-designed chamber. Raising the oxygen pressure increases the amount of oxygen dissolved in plasma. This can increase oxygen delivery to tissues, including areas where circulation is compromised, although oxygen delivery also depends on blood flow and the condition of the tissue.

That physiological rationale makes hyperbaric oxygen a subject of clinical interest in wounds. It does not, by itself, establish that a particular ulcer will heal or that treatment is suitable for a particular patient. The question for clinical research is how the proposed mechanism relates to meaningful outcomes and to the risks and demands of treatment.

  • Oxygen tension: the pressure exerted by oxygen in a tissue or fluid; it helps describe oxygen availability.
  • Perfusion: blood flow through tissue, which supplies oxygen and carries away metabolic products.
  • Ischaemia: inadequate blood supply to a tissue, which can limit oxygen delivery and damage cells.
  • Wound healing: a coordinated process involving viable tissue, blood supply, infection control and repair.

What does the article’s subject mean for diving medicine?

The article sits at the intersection of hyperbaric medicine and a systemic disease. Divers encounter pressure and breathing gases as parts of a controlled environment; hyperbaric clinicians use pressure as a treatment condition. In both settings, pressure changes the physical conditions under which gases dissolve and move, while the patient’s physiology determines how those changes matter.

Sickle cell disease also raises a distinct concern for diving: impaired microvascular flow and episodes of tissue oxygen stress are relevant to the body’s response to exertion, immersion and gas exposure. A clinical article on hyperbaric treatment of ulcers is not a diving fitness assessment. Divers with sickle cell disease need individual assessment by a physician experienced in diving medicine.

How are hyperbaric wound questions assessed?

Studies of hyperbaric treatment for wounds need to consider the wound’s cause and severity, the patient’s underlying condition, and what care accompanies chamber treatment. Outcomes may include wound closure, healing time, recurrence and adverse effects. A physiological response to oxygen is not interchangeable with a demonstrated improvement in patient-centred outcomes.

Interpretation also depends on treatment details and comparison: pressure, oxygen exposure, treatment schedule and other wound care can all matter. For sickle cell ulcers, the underlying disease makes it especially important to distinguish a local intervention from management of the broader condition. Clinicians weigh potential benefit against treatment burden and risks, including oxygen-related effects.

What should readers take from this 1991 subject?

Rudge FW’s article belongs to the clinical literature exploring whether hyperbaric oxygen can be applied to a difficult wound problem. Its subject remains useful for understanding how hyperbaric medicine tests a physiological rationale in a specific disease context, rather than treating increased oxygen pressure as a universal remedy.

The bibliographic record identifies the publication as a journal article in J. Hyperbaric Med 6(1), published in 1991. Readers considering its place in current practice should consult the article itself alongside contemporary clinical guidance; treatment decisions require specialist assessment.

Frequently asked questions

What is the subject of this publication?
It addresses hyperbaric oxygen therapy in relation to leg ulcers associated with sickle cell disease.
Why might oxygen under pressure be considered for a wound?
Increased oxygen pressure can raise the amount of oxygen dissolved in plasma and may affect oxygen availability in tissue. Whether that translates into clinical benefit depends on the wound and the patient’s condition.
Does this article establish whether someone with sickle cell disease can dive?
No. A paper about hyperbaric treatment of ulcers is not a diving fitness evaluation. Anyone with sickle cell disease considering diving should seek an individual assessment from a diving-medicine physician.
