If you're interested in taking admission in the IT department at SK DAV Government College, Rourkela, despite the admission deadlines, your situation involving a severe head injury and surgery may be considered on humanitarian grounds. Here’s what you can do:

1. **Contact the College Administration:** Reach out to the college administration through phone or email, explaining your medical condition and why you missed the admission deadline. Provide medical records, such as a doctor’s certificate or hospital discharge summary, to support your case.

2. **Visit the College in Person:** If you're able, visit the college personally or have a family member or representative do so. Speaking directly with the principal or admission officers may give you a better chance of securing admission, especially if they understand your situation.

3. **Submit an Application with a Medical Certificate:** Many colleges allow for exceptional cases, especially on medical grounds. Attach your medical documents along with a formal written request for consideration due to your injury.

4. **Explore Lateral Entry or Next Session Admission:** If the college cannot admit you this year, ask about possibilities for lateral entry in the next session or deferment options.

Persistence and clear communication about your situation will increase the likelihood of receiving a favorable response.
