INTRODUCTION
Diaphragmatic hernias presented to the hospital were due to trauma. A total of 5 procedures were done successfully using an anesthesia machine rebreathing bag for ventilation.
OBJECTIVES
To clear the thoracic region from herniated abdominal organs and return the normal respiration of the patient
METHODS
Complete blood count, serum chemistry, urinalysis and radiographs were performed prior to surgery of patients. Two teams of doctors were utilized; one to perform the surgery and other to do the anesthesia and life support. A ventral midline incision is made towards the cranial part of the abdomen from xyphoid to umbilicus.
Abdominal organs are then retracted into place. The Thoracic cavity is washed with saline solution and suctioned well while patient is on an inclined plane with the head higher than the rest of the body. Diaphragm closure is done dorsally to ventrally with a continuous suture pattern. Either an absorbable or non absorbable monofilament suture can be used to close the diaphragm.
The important part is 4breaths/minute or 1puff/15sec using the right bag for the patient size. Before total closure of the tear, a Fr.7 tube is inserted and negative pressure is applied. Timing is essential. Tighten the last knot while removing the tube to allow negative pressure to remain inside the thorax. Stop the assisted breathing and monitor the patient’s normal respiration. The abdomen is then closed routinely.
RESULTS
All five cases were operated on successfully, with only one experiencing respiratory complications.
CONCLUSIONS
Diaphragmatic hernias may be successfully repaired without the use of a ventilator

INTRODUCTION
Pulmonary hypertension (PH) is defined as persistent increase in pulmonary vasculature pressure and occurs as a primary or secondary disease.
OBJECTIVES
To evaluate retrospectively the prevalence and characteristics of PH in a random sample of 100 dogs from a database.
METHODS
The database included 2123 dogs scanned in Hong Kong over a period of 2.5 years. PH was diagnosed from velocity of tricuspid regurgitant jet > 2.8 m/s. Dogs were classified into different groups on the basis of their diagnoses. Age, breed, sex and clinical signs have been compared among different groups. In dogs where follow up echocardiograms were available, success of PH therapy was evaluated.
RESULTS
In the sample of 100 dogs there were 54 dogs diagnosed with PH; there were 40.7% of dogs with mild PH, 38.9% with moderate PH and 20.4% with severe PH. In the random sample 60% of all mitral valve disease cases had PH (89% of Class B2 or C). PH was more common in male dogs. Among the dogs with PH there were 92.6% of small breed dogs. Most common breeds of dogs with PH were Shih Tzu and Pekingese. Most common clinical signs of dogs with PH were exercise intolerance, syncope, cough and dyspnea/ tachypnea. Dogs were treated for primary disease and pimobendan and/or sildenafil. Improvement of clinical signs and a decrease in pulmonary arterial pressure was observed in 76.2% of dogs with average decrease in pressure of 27%.
CONCLUSIONS
PH is common in Hong Kongese dogs.
