2.3 Research Methods
The control group received routine care, including health education, psychological counseling and traditional anesthesia resuscitation care. On the basis of the control group, patients in the study group were added the Da Vinci specialist group for perianaesthesia nursing, mainly including:
(1) Robot nursing team: Robot surgery is complex and delicate, and has high requirements for details of anesthesia care. The department needs to establish a professional robot anesthesia nursing cooperation team, which is composed of nurses who have passed the systematic training and examination of the department special committee, and are required to master the perianesthesia nursing of Da Vinci Specialist group.
(2) Environmental management: the indoor temperature should be controlled at 22–24 ℃ and humidity should be controlled at 50%-60%. The resuscitate unit should prepare equipment such as kindly electric monitoring, ventilator and negative pressure suction, and prepare first-aid items. Try to arrange patients to beds near the nurse station.
(3) Monitoring and maintenance of respiratory tract: ①If the tracheal tube is not removed, adjust ventilator parameters to assist breathing as instructed by the doctor, and closely monitor the waveform and frequency of breathing. ②Patients with tracheal tube removed were given continuous oxygen inhalation by mask to maintain oxygen saturation above 94%, and patients' vital signs were monitored. ③To guide the breath and cough after waking, smoking history, most patients with tracheal intubation in the process of the respiratory tract, there will be a certain degree of damage of postoperative patients stay in bed for a long time, and the reason of wound pain can't do take a deep breath and cough movement, after pulling the endotracheal tube should do explain the necessity of respiratory function training, guide the patients to learn effective respiratory function exercise, prevent the occurrence of pulmonary complications.
(4) Posture care: the head of the bed is raised 15–20°, which is conducive to drainage and breathing. After the patient is awake, the patient should be assisted to take a comfortable posture.
(5) Complications related to artificial CO2 pneumoperitoneum: Due to high intraoperative pneumoperitoneum pressure, long operation time and other reasons, excessive CO2 is easily absorbed intraoperatively, which may cause subcutaneous emphysema and hypercapnia. ETCO2 and respiratory status can be monitored continuously after surgery, and blood gas indicators can be monitored repeatedly if necessary. When patients have CO2 storage,ventilation can be increased by adjusting respiratory rate or tidal volume to correct insufficient ventilation and avoid acid-base metabolism imbalance.
(6) Agitation nursing: Patients with long-term robotic surgery have a high incidence of postoperative agitation and delirium, and rapid hyperventilation should be avoided. In order to avoid overcorrection, at the same time do a good job of patient restraint. Postoperative pain and patients' discomfort to the pipeline may be important factors of agitation, which can be prevented and corrected by using sedative and analgesic drugs as prescribed by the doctor.
(7) Pain care: the postoperative pain of robotic surgery is lighter than that of traditional open surgery. Patients' expectations for minimally invasive surgery and requirements for rapid postoperative recovery make the postoperative analgesia more demanding. When the VAS ≥ 4, and the patient appears irritable, rapid pulse, hypertension, etc., the doctor should be informed as soon as possible, and symptomatic treatment such as analgesia, antihypertensive should be given. When VA ≤ 3 points, if the patient can tolerate pain, the patient can be assisted to press the analgesic pump to relieve pain.
(8) Pipeline care: To ensure the smooth flow of infusion tubes and drainage tubes, straighten out the messy pipes, fix all kinds of drainage tubes and make good marks. At the same time, closely monitor the inflow and outflow, squeeze the drainage tube every hour, pay attention to the drainage flow and drainage color, and timely remind the doctor of any abnormality
(9) Wound care: although the wound is small, there are many wounds. It is necessary to carefully observe whether the wound oozes blood and fluid, and whether the dressing is dry.
(10) Temperature care: the postoperative time is long, so that patients are prone to postoperative hypothermia, easy to cause chills, so postoperative temperature detection should be routine. And use heating equipment to keep warm, prevent and treat adverse complications caused by hypothermia.
(11) Skin care: The robot operation time is longer than laparotomy and laparoscopic surgery. In addition, due to the gravity of the robotic arm, the patient is older, which is easy to lead to different degrees of congestion and edema of soft tissue. Therefore, the observation of the skin of the ribs on both sides is strengthened.
(12) Psychological nursing: Try to meet the needs of patients, help to build a positive mindset, improve the quality of service and patient satisfaction.
(13) Health education: When leaving the PACU, make a good case transfer to the surgeon, and teach the use of analgesia pump to the patients and their families.
2.4 Observation Indicators
(1) The differences of heart rate (HR) and mean arterial pressure (MAP) between the two groups before and after nursing were recorded.
(2) Postoperative indicators of the two groups were recorded, including wake time, spontaneous breathing time, extubation time, daily sleep time and total recovery time.
(3) The differences of pain and sleep quality between the two groups before and after nursing were evaluated, and visual analogue scale (VAS) was used for pain (Myles & Myles & Galagher W et al., 2017). A score of 0 is no pain and 10 is severe pain. The sleep quality was evaluated by Pittsburgh Sleep Index scale (PSQI) (Almojali & Almalki & Alothman et al., 2017), with 18 self-rated items in total. Each component is scored on a scale of 0 to 3, and the final cumulative score is 0 to 21 points. The higher the score, the worse sleep quality.
(4) The difference in postoperative satisfaction and postoperative nursing risk rate between the two groups were evaluated, and the satisfaction was evaluated by a self-made questionnaire of our hospital (Dunstan & Scott, 2020; Xie & Liang & Lu et al., 2021). The full score is 100, the higher the score is, the better the patient satisfaction is, and the incidence of adverse symptoms includes the incidence of complications such as agitation, pain.
