Dibekukan Untuk Hidup Kembali / Frozen Back To Life

VIVAnews - Bayi bernama Samaa Zohir baru berusia sebulan saat dokter memutuskan ia harus dioperasi, jika tidak akibatnya bisa fatal: maut.

Sudah sejak lahir, kondisi Samaa abnormal. Pembuluh darah yang mengalir ke jantungnya terhubung dengan cara yang salah. Harusnya, pembuluh darah itu membawa darah beroksigen dari paru-paru ke sisi kiri jantung. Yang terjadi, justru sebaliknya.

Namun, mengoperasi jantung bayi seukuran lebih kecil dari bola golf  jelas tantangan besar untuk para dokter dari Great Ormond Street Hospital, London. Akhirnya sebuah terobosan revolusioner diputuskan: bayi ini dibekukan sampai mati.

Samaa dibuat mati suri. Caranya, dokter meletakkan kantung berisi es di sekeliling kepala bayi itu--darahnya didinginkan dari suhu normal, 37 derajat Celcius, menjadi 18 derajat menggunakan mesin bypass jantung dan paru-paru. 

Tak hanya itu, para dokter nekat itu juga menghentikan detak jantungnya dengan cara menyuntikkan obat dan mematikan mesin bypass. Di titik ini, secara klinis, bayi Samaa telah meninggal dunia. Tubuhnya hampir sepenuhnya kehabisan darah.

Sementara itu, ahli bedah kardiotoraks Tain-Yen Hsia dan timnya harus bekerja melawan waktu. Jendela keselamatan maksimum (maximum window of safety) adalah 50 menit--sebelum jantung orok ini harus di-restart untuk mencegah kerusakan pada otak dan organ dalam.

Untungnya, Samaa tak harus menunggu 50 menit untuk hidup kembali. Dokter berhasil membawanya kembali ke dunia dalam waktu 23 menit.

Setelah mesin dihidupkan, darah hangat langsung terpompa dan mengembalikan suhu tubuhnya ke titik normal, 37 derajat Celcius. Jantung mungil itu pun kembali berdetak.

Mengapa Samaa harus dibekukan? Menurut Dokter Hsia, tim medis harus melakukan operasi mikro. Sebab, mereka berurusan dengan pembuluh darah yang setipis kertas beras (rice paper). Satu-satunya cara yang bisa dilakukan adalah membekukan tubuh dan menghentikan sirkulasi darah agar pasien masuk ke fase hipothermia.

"Ini seperti mencemplungkan bayi ke dalam seember air es. Saat menghentikan jantung, kami harus melakukan operasi secepatnya dengan tingkat presisi tinggi," katanya. "Tidak ada ruang melakukan kesalahan sekecil apapun."

Selang lima bulan  setelah operasi yang dramatis, Samaa telah sembuh total. Satu-satunya bekas operasi yang dimiliki bayi asal Finchley, London Utara ini, adalah bekas luka di dadanya. Ibunya, Roosina Ahmed (30) dengan haru menceritakan saat-saat terberat dalam hidupnya.

"Saat pertama anakku membuka matanya, tak terkira bahagia yang saya rasakan. Bayangkan, selama 20 menit ia terbaring dengan tubuh dingin, tanpa kehidupan," kata Roosina seperti dimuat Daily Mail, Minggu, 17 Oktober 2010.

Perubahan drastis juga dialami Samaa pasca operasi. Jika sebelumnya ia bayi yang sangat lemah, bahkan untuk menangis sekalipun, kini dia gembul makan dan bermain tak kenal lelah.

Why Samaa must be frozen? According to Dr. Hsia, the medical team must perform micro surgery. Because, they are dealing with blood vessels as thin as rice paper (rice paper). The only way that can be done is to freeze the body and stop the blood circulation for patients entered into phase hipothermia.


"It's like a baby plunge into a bucket of ice water. When the heart stops, we have to do surgery as soon as possible with high precision," he said. "There is no room to do the slightest mistake."


Five months after a dramatic operation, Samaa has been recovered. The only operation that owned the former home baby Finchley, north London, is a scar on his chest. His mother, Roosina Ahmed (30) with emotion tells toughest moments in his life.
