Nursing Ethical Principles II01:27

Nursing Ethical Principles II

Ethical principles are essential in guiding nurses to fulfill their responsibilities, focusing on the quality of nursing care and decision-making. These principles, including autonomy, beneficence, non-maleficence, justice, and fidelity, shape the ethical framework within healthcare settings.
Consider the following scenario, which illustrates how these principles are applied in the care of Mr. John, a fifty-year-old teacher diagnosed with metastatic liver cancer.
Initially, Mr. John's cancer...
Cancer Therapies02:49

Cancer Therapies

Cancer therapies are various modes of treatment, such as surgery, radiation therapy, and chemotherapy that are administered to cancer patients.
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...

Nuclear Overhauser Enhancement (NOE)01:06

Nuclear Overhauser Enhancement (NOE)

Irradiation of a spin-active nucleus causes an increase or decrease in the signal intensity of neighboring nuclei that are not necessarily chemically bonded or involved in J-coupling. This phenomenon, called the nuclear Overhauser enhancement (NOE), results from through-space interactions between the nuclear spins. The NOE effect decreases with increasing internuclear distance and is generally not observed beyond 4 angstroms. In NOE, dipole-dipole interactions between neighboring spin-active...
Ethical Issues01:27

Ethical Issues

Nurses are essential in patient care, upholding the ethical principles of their profession and effectively navigating ethical dilemmas. Neglecting ethical issues can lead to inadequate patient care, compromised therapeutic relationships, and moral distress among healthcare workers.

Techniques of therapeutic communication I: Active Listening, Sharing Observations, Validation, and Using Touch

The history of therapeutic communication can be traced back to Florence Nightingale, who emphasized the importance of developing trusting relationships with patients. She taught that the presence of nurses with patients results in therapeutic healing.
Therapeutic communication is not the same as social interaction. Social interaction has no goal or purpose and consists of casual information sharing, whereas therapeutic communication has a plan or purpose for the conversation. Therapeutic...

Area of Science:

  • Minimally invasive surgical techniques
  • Surgical oncology
  • Endoscopic surgery

Background:

  • The trend in abdominal surgery is towards reduced invasiveness and patient trauma.
  • Laparoscopic surgery has evolved for benign and malignant diseases, offering benefits like reduced infection and pain.
  • Laparoscopic approaches are now accepted as alternatives to open surgery for abdominal cancers.

Purpose of the Study:

  • To review the evolution and benefits of laparoscopic surgery in cancer treatment.
  • To explore the potential of Natural Orifice Translumenal Endoscopic Surgery (NOTES) in cancer management.
  • To discuss the challenges and future outlook for NOTES in surgical oncology.

Main Methods:

  • Review of current literature on laparoscopic and NOTES techniques in abdominal cancer surgery.
  • Analysis of reported benefits and challenges associated with minimally invasive approaches.
  • Discussion of the developmental stage and future prospects of NOTES.

Main Results:

  • Laparoscopic surgery demonstrates significant advantages for cancer patients, including fewer wound infections, less pain, and quicker recovery.
  • NOTES is an emerging technique with proposed applications in cancer surgery, but is still in early development.
  • Significant challenges remain in developing NOTES equipment, techniques, and proving its safety and efficacy for widespread clinical use.

Conclusions:

  • Laparoscopic surgery is a validated alternative to open surgery for many abdominal cancers.
  • NOTES holds potential for further reducing surgical invasiveness but requires substantial development and clinical validation.
  • A cautious approach ('watchful waiting') is recommended for surgeons regarding the adoption of NOTES until its efficacy and safety are conclusively demonstrated.
