Highly stable, flexible delivery of microjoule-level ultrafast pulses in vacuumized anti-resonant hollow-core fibers for active synchronization.

We demonstrate the stable and flexible light delivery of multi-microjoule, sub-200-fs pulses over a ∼10-m-long vacuumized anti-resonant hollow-core fiber (AR-HCF), which was successfully used for high-performance pulse synchronization. Compared with the pulse train launched into the AR-HCF, the transmitted pulse train out of the fiber exhibits excellent stabilities in pulse power and spectrum, with pointing stability largely improved. The walk-off between the fiber-delivery and the other free-space-propagation pulse trains, in an open loop, was measured to be <6 fs root mean square (rms) over 90 minutes, corresponding to a relative optical-path variation of <2 × 10-7. This walk-off can be further suppressed to ∼2 fs rms simply by using an active control loop, highlighting the great application potentials of this AR-HCF setup in large-scale laser and accelerator facilities.

Postoperative nursing care of a child with pulmonary artery displacement combined with slide tracheobronchial plasty.

Generally, pulmonary artery sling operation involves the pulmonary artery transplantation to be cut off. Nursing care is focused on the postoperative pulmonary vascular anastomosis, respiratory tract, and blood pressure after surgery. We report the case of an infant who underwent pulmonary artery tracheal transposition combined with Slide keratoplasty, where the pulmonary artery transplantation was not cut off. We highlight that postoperative pulmonary artery blood flow to the unobstructed airway and airway reconstruction surgery should be focused on to help children recover and ensure successful surgery. This case study reports the postoperative nursing experience of one patient with pulmonary artery sling undergoing pulmonary tracheal transposition combined with Slide arthroplasty. This demonstrates that throughout the postoperative care, airway management should be focused on to maintain circulation stability in the early postoperative period, and corresponding measures such as posture management, atomization inhalation, and improved chest physical therapy should be applied according to the special surgical method of the case in order to reduce airway complications and to improve the surgical success rate of children with pulmonary artery sling undergoing pulmonary tracheal transposition combined with Slide arthroplasty. In similar cases, after pulmonary tracheal transposition and Slide angioplasty, the doctors and nurses should pay attention to early circulation stability and focus on airway management through careful treatment and nursing, so as to promote the child's recovery.

A nurse-driven enhanced recovery after surgery (ERAS) nursing program for geriatric patients following lung surgery.

Enhanced recovery after surgery (ERAS) is a multiprofessional, multidisciplinary and evidence-based program that aims to reduce complications, improve overall prognosis, shorten hospital stays, and promote fast recovery following major surgery. Nurses play a crucial role in the successful implementation of the ERAS program. Therefore, this research focuses on the trajectory optimized and acquired by nurses in the enhanced recovery of elderly patients undergoing radical surgery for lung cancer. This study concludes that the implementation of the proposed ERAS preoperative point-of-care trajectory is highly beneficial for improved outcomes and enhanced recovery of geriatric patients following lung surgery.
