Cadavers as teachers: the dissecting room experience in Thailand

Source of bodies

In Thailand, which remained an independent kingdom throughout the colonial period, Western medicine was introduced in the middle of the 19th century, mainly by American missionaries.6 7 Use of anatomical dissection for teaching was introduced around 1900. Today, gross anatomy is taught in a preclinical dissection course for second year medical students. Dissection technique and students' proficiency levels are no different from Western standards.

Cadavers are acquired through unremunerated voluntary donation. Like most Western countries, Thailand used to use unclaimed bodies for anatomical dissection, which resulted in a shortage of cadavers until about 30 years ago. Today, it no longer has any shortage of willing donors, even though most Thais are Buddhist and remain reluctant to donate organs for transplantation because of their belief in rebirth.8

We found at least two factors that have helped Thai people overcome their reservations. One is that King Bhumibol has officially approved body donation—a strong incentive in Thai society. The second factor is that donors attain the highly regarded status of ajarn yai, great teacher. Teachers in Thailand are respected to an extent unfamiliar to Westerners. This respect is formalised in a ceremony called waikhru (honour the teacher), which takes place annually in Thai schools and universities.

The custom of calling the donors great teacher can be traced back to the very first Thai body donor, a professor of literature who was inspired to donate his body in the 1930s by the idea of remaining a teacher after death. He is commemorated in the anatomical museum of Siriraj Hospital, Bangkok, where his skeleton is on display.

Ceremonies establish a new relationship

The status of ajarn yai is mainly conferred by two ceremonies, which seem to be a powerful means to define the atmosphere and an ethical framework for dissection courses in Thailand: the dedication ceremony some days before the first course session and the cremation ceremony at the end of the course. These ceremonies are important events in faculty life and are attended by the highest officials and students from different years.

In the dedication ceremony, faculty members, students, relatives of the deceased, and Buddhist monks come together in the dissecting room to pray and chant. The donors (that is, the cadavers) are present and are offered ritual flower bouquets. The donors' names are read aloud and they are conferred the title of ajarn (teacher). The monks are given a meal and gifts as a symbolic way of giving to the deceased.

This ceremony is an adapted mortuary rite. A major symbolic theme is to “make merit” for the spirits of the deceased. Put simply, transferring merit helps the winyan (spirit or soul) go to heaven and increases its chances for a better rebirth. The ceremony is an introduction in a double sense of the word: it marks the beginning of the course and makes the student known to the cadaver. Rather than focusing on emotional coping (as claimed for some ceremonies attached to Western dissection courses9^–12), it seems to be primarily centred around establishing a new relationship. Students enter a relationship with their ajarn yai that they have learnt from early childhood: a relationship of respect for a highly valued teacher.

The cremation of the dissected bodies occasions an even bigger ceremony. It culminates in a large procession led by monks, in which the students carry their ajarn yai to the cremation building. Booklets are distributed that include the donors' pictures, their address, a short curriculum vitae, and words of condolence and gratitude from the faculty and students (box). 13

In the dissecting room

Just as for Western students, the dissection of cadavers constitutes the breaking of a taboo for Thai students. Although we never saw any student showing open signs of disgust or revulsion, or of deliberately avoiding contact with the cadaver, a certain fearful expectation is palpable on the first day of the course. But this gives way to a truly relaxed atmosphere within a day or two.

During the course the cadavers are always referred to as ajarn yai, never as sop (cadaver). Respect for these teachers is paramount. One student told us she came to respect them “even more than the living teachers.” Sometimes cadavers are greeted with a wai, the Thai greeting bow. Some students bring them flowers and many intend to pray for their ajarn yai at the temple (at least “after the exams”). The name, age, and cause of death of the donor are usually indicated on each dissecting table. Students can readily reproduce the name when asked to do so, and many doctors we asked still remember the name of their ajarn yai from their student days.

Even dissection of a deceased acquaintance or relative does not seem to be something beyond imagination, as it is in the West (as testified by circulating “horror stories”2). It is not uncommon in Thai anatomy departments to have the remains of former staff members, often still well remembered, on display in showcases together with a picture and flowers. We were told the story of a student whose grandfather, himself a medical doctor, had specifically asked her to dissect his body after death. She did so, and was thought to have especially good support from his spirit thereafter.

The cadaver as a person

Donor anonymity is obviously not an issue in Thailand as it usually is in the West.14 More than that, Thai students seem to have fewer problems with seeing the person in their cadaver. Cadavers are greeted and given flowers, they participate in ceremonies, they have a name, an age, and a history. Thai students see the cadaver as their teacher and thus attribute a social role and status to it.

In the West, the most common way of bestowing more personal qualities on the cadaver has been to regard it as the students' “first patient.”12 15 However, there are important differences from the Thai situation. The “cadaver as patient” concept is a suggestion by some authors rather than a lived reality. It is certainly not taken as literally by Western students as the teacher concept is by Thai students. Nevertheless, some Western anatomists actively promote viewing cadavers as patients to encourage respectful treatment. It could be argued, however, that students who treat cadavers like patients might later treat their patients like cadavers, which could have a negative effect on medical socialisation.16 17 Conceptualising the cadaver as a teacher avoids this problem as the cadaver is closer to a respected non-medical person than to a medical object.

Ambiguous man

Hafferty aptly called the cadaver an “ambiguous man” to denote its material as well as its personal qualities.18 We feel that Thai medical schools have found a remarkable way of handling this ambiguity. Although the cadaver can obviously be handled like an object in the dissection process, it can at the same time be seen as a respected teacher. In Thailand, the cadaver is treated much more like a social person and less like an object—or rather the difference between the two is less acutely felt than in the West.

We are not in a position to judge whether the Thai approach will produce better doctors in the end. But we do think that it allays some of the ethical difficulties in dealing with human cadavers. Indeed, medical practitioners face many ambiguities, including the need to show both detachment and empathetic care in the treatment of patients.19 Therefore, learning how to deal with such ambiguities is in itself an important aspect of medical training. In this respect, the West has something to learn from Thailand.
